Chapter 1 Configuration
Congratulations on your purchase of a StarDot NetCam network camera with
integrated web server. NetCam provides the highest quality live still images in a
remote camera that can be connected to a network or a modem. With proper usage,
NetCam will provide many years of quality remote imaging. We recommend that you
read this manual carefully to completely understand NetCam’s capabilities.
1.1 Before You Start
This manual guides you through the basic setup procedure for NetCam
and provides a detailed resource of the camera’s advanced options and
capabilities.
Setting up NetCam consists of three steps. The first step is to configure
NetCam’s network or dial-out settings. The second step is to configure
NetCam to upload images to a web server (this step is optional). The third
step is the physical installation of the camera.
1.2 What’s Included and What’s Required
The NetCam package includes a NetCam camera, a lens, a wall mount, a
power supply, a combo network/power cable, a null modem serial cable and
the StarDot Tools software on CD-ROM. The Dial-Out package includes an
external modem and modem cable (instead of the network cable). In order
to use NetCam, you will need the following:
•
Power source
•
A computer – for configuring NetCam and for viewing NetCam
images (viewing requires Java-enabled web browser)
Note: A computer is not necessary to operate NetCam, only to configure it.
•
Network connectivity (LAN, cable modem, DSL, T-1, Dial-Up
Internet Account, Satellite Modem, etc.)
•
Web server space (only required when configured as Dial-Out ISP
camera)

1.4 Connecting NetCam to a Network
The StarDot Tools software can be used find NetCam’s IP address or
to configure NetCam with a Setup Wizard.
Install the StarDot Tools software by inserting the CD-ROM and
running setup.exe(it should run automatically).
If your network has a router or server that auto assigns IP addresses
(DHCP), StarDot Tools will find NetCam’s IP address and display
it in the software. To access NetCam, simply double-click its IP
address. Turn to Chapter 3 for assistance on configuring NetCam.
If your network does not auto-assign IP addresses, you’ll need to
configure NetCam via the included serial cable. Connect one end of
the null model serial cable to the S1 port of NetCam and the other
end into an available serial port on your PC.
Connect NetCam into a network router, hub or switch with a standard
CAT 5 network cable or with the included Combo Ethernet/Power
Cable (see illustration).
‘
In StarDot Tools, click the Setup Wizard button.
Follow the steps in the Setup Wizard. If you’re unsure of some of
the answers or you’d like more information on connecting NetCam
to the Internet or your private network, read the next section,
“An Overview of NetCam Connectivity”.

1.5 An Overview of Network Connectivity
ALAN or network connection is the simplest configuration for NetCam.
NetCam simply needs an IP address (and other networking parameters) to
make the live images and configuration menus accessible from any web
browser on the network. There are two ways NetCam can be assigned an
IP address: automatically or manually.
Automatic IP Assignment (DHCP)
NetCam is shipped in an automatic IP assignment mode called DHCP
(Dynamic Host Configuration Protocol). If your network has a DHCPserver
(in most cases, a router), it will automatically assign the necessary network
parameters to NetCam. Before you can access the camera, you will need
to know which IP address was assigned to NetCam. Use the StarDot Tools
software to find NetCam’s IP address.
Manual IP Assignment
If you want to assign NetCam a permanent IP address, you will need
the following information:
•
•
•
•
IP Address (example: 192.168.1.5)
Subnet Mask (example: 255.255.255.0)
Gateway (example: 192.168.1.1)
DNS Servers (example: 24.1.179.1, 24.1.179.2)
NetCam

If you are installing NetCam on a company network, you will probably want
to get this information from your system administrator.
The easiest way to configure NetCam manually is to connect NetCam to
a serial port on your computer. Plug one end of the null modem serial cable
into the S1 port on the back of NetCam and the other end into an available
9-pin serial port on the back of your computer. Use the included StarDot
Tools software to configure NetCam.
If you don’t have a serial port or are using a non-Windows machine,
you have a few options.
If NetCam is connected to a network with a DHCP server and your
computer is not running Windows, you can log into your router (or whatever
is acting as your DHCP server) and view the DHCP clients table. NetCam
will have the MAC address starting with 00:30:F4. Take note of the IP
address and enter it in your web browser. Click on the configuration link,
visit the network tab and assign NetCam a manual IP address (outside of
the router’s DHCP range).
If NetCam is connected to a network without a DHCP server
(IP addresses are not automatically assigned) and your computer is not
running Windows, you’ll have to manually assign NetCam an IP address.
This requires terminal emulation software and the included null serial cable.
On a Macintosh or on a Windows computer without a serial port, you’ll
need a USB RS-232 adapter.
To talk directly to NetCam via the included serial cable, set your
terminal software to a bitrate of 38,400 (8/N/1). Log in with admin / admin
and use the following commands to assign NetCam a temporary IP address.
Once the IP has been assigned, browse to NetCam with a web browser and
configure NetCam to have a permanent static IP address.
In the following example, NetCam is being assigned a temporary IP
address of 192.168.0.2 via a terminal program connected to the S1 port on
the back of NetCam:
ifconfig eth0 192.168.0.2
route add -net 192.168.0.0 netmask 255.255.255.0 eth0
Remember, once you can reach NetCam via its temporary IP address,
you’ll want to immediately assign it a permanent static IP address in the
network configuration menu.

1.6 Connecting NetCam to a Modem
In order to use NetCam with an analog phone line, you will need the
Dial-Out NetCam package (CAM-NETx2, which comes with an external
modem and cable), a dial-up ISP account, and an analog phone line.
Install the StarDot Tools software by inserting the included
CD-ROM and running setup.exe.
Connect one end of the null model serial cable to the S1 port of
NetCam and the other end into an available serial port on your PC.
Connect the round end of the modem cable into the external modem
and plug the modem power supply into the modem (modem and
modem cable both included with remote package).
Plug the DB9 end of the modem cable into the S0 port of NetCam.
Run the StarDot Tools software and click on the Setup Wizard
button.
‘
Follow the steps in the Setup Wizard. When asked for modem type,
select 3JTech.
Test your configuration locally first. Once successful, you can
place NetCam and the modem remotely and it will automatically dial
out to the Internet and upload images according to the set schedule.

Chapter 2 Installation
Before installing NetCam in its final location, it is important to configure
and test it first (see Chapter 1).
2.1 Installing NetCam
Ethernet Connection
If NetCam will be connected directly to an Ethernet network, measure
the distance from NetCam to the nearest Ethernet hub or switch. This
distance should not exceed 300 feet. If you wish to extend the distance
further than 300 feet, you can add an Ethernet hub or switch.
Running Separate Ethernet and Power
Run standard CAT 5 or better Ethernet cable from the hub/switch to
the NET jack on the back of NetCam. Plug the included power supply into
the back of NetCam.
Running Combined Ethernet and Power
To save the hassle of running both power and network cables (or having
to have a 110V power supply at the camera location), NetCam ships with
a 50 ft. combo Ethernet/power cable. You can use this in place of standard
CAT 5 network cable. Plug the included power supply into the power tail
jack on one side of the cable and plug the network plug into a hub. The
other end of the cable plugs into the NetCam’s PWR and NET jacks (see
illustration in Chapter 1.4).
If you need a longer cable, StarDot offers lengths of 100, 200 and 300
feet. Keep in mind that the longer combo cable lengths require a power
supply with higher voltage output (voltage drops over the length of a cable).
The appropriate power supply is included with the longer combo cables.
Modem Connection
If NetCam’s connection to the Internet will be a dial-out ISPconnection,
an external modem and modem cable are required (these are provided with
the Dial-Out NetCam package).
Connect the external modem’s power supply into an AC wall outlet.
Connect the external modem into a phone jack using a standard telephone
cable. Using the included DB9 Female to round connector cable, connect
the external modem into the S0 port on the back of NetCam.
It is important that NetCam be pre-configured for a dial-out modem
connection before placing the camera in its final installation location (see
Chapter 1.6).

2.2 Installing NetCam Outdoors
NetCam is an outdoor-capable camera, but two important steps must
be taken before NetCam can be used in an outdoor environment. NetCam’s
lens must be adjusted for daylight imaging, and NetCam must be enclosed
in an outdoor enclosure.
Lens Adjustment
NetCam ships with a manual iris lens (if you ordered a different lens
with NetCam, it will most likely have a manual iris). The iris must be closed
down to a pinhole size before using the camera in daylight lighting. If
the lens has markings on the iris ring, you will want to close the iris down
to ƒ16 or larger (the larger the ƒ-stop, the smaller the iris). If the lens does
not have numerical markings on the iris ring (it may just show “open” and
“close” with arrows), look into the lens and turn the iris until the hole is
about the size of a pinhole.
The pinhole size is an approximation. To precisely set the iris, add $e to
the image overlay (the text printed on the image). This will print the current
exposure. During daylight, this value should fall between 100 and 500. You
generally do not want to want to see the exposure with a value below 100.
If your exposure is reading below 100, adjust the iris smaller until it reads
between 100 and 500. Note: Make sure Auto Exposure is enabled.
Failure to set the iris properly in daylight lighting may result in
streaky image quality and will prematurely cause permanent damage
to the CCD sensor. NetCam’s auto exposure logic will automatically
compensate for changes in brightness throughout the day by adjusting the
exposure. NetCam can take great quality images from dawn to dusk with a
manual iris lens, provided it’s set properly. For more information on daylight
imaging and how to achieve the best quality possible, see Chapter 4.1.
Mounting the Camera
To mount NetCam outdoors, it must first be encased in an outdoor
enclosure (different models are available from StarDot Technologies, see
http://www.stardot-tech.com/netcam).
Install NetCam in an outdoor enclosure and adjust the internal mount
so NetCam’s lens is up against the enclosure window. This helps to reduce
glare.
Determine where NetCam will be pointing and where you’d like to
mount it. The outdoor enclosures can be mounted on a horizontal or vertical
surface. When aiming the camera, factors such as sun travel and amount
of visible sky can vastly affect the quality of the image. For imaging tips,
see Chapter 4.1.

Chapter 3 Accessing NetCam
3.1 Viewing NetCam’s Images
Any Java-enabled browser can be used to view the live images.
Type NetCam’s IP address in your browser’s address bar (example:
3.2 Accessing NetCam’s Configuration Menus
Virtually any web browser can be used to access NetCam’s configu-
ration menus. To access these menus, type NetCam’s IP address in your
bring up the live image page. Click on the Configuration link. You will be
prompted for a User Name and Password. Use adminfor both.
Tip: We highly recommend that you change the default password. To do so, see
Chapter 3.8.
3.3 Image Properties
All image-related configuration options are located on the Image
Properties page. After making changes, click the Apply button to save new
settings in the camera.
EXPOSURE
Auto vs. Manual
Unless you have a controlled (fixed) lighting condition, you will almost
always want to leave Auto Exposure enabled.
Page 12
NetCam
Download from Www.Somanuals.com. All Manuals Search And Download.
Auto Exposure
Enabling Auto Exposure causes NetCam to automatically adjust
the image exposure based on the overall brightness of the image. The
following functions are only implemented when Auto Exposure is
enabled.
•
Brightness - The higher the number, the brighter the picture. The
default value is 60.
•
Sensitivity - This value rarely needs to be adjusted. It sets the
sensitivity of the Auto Exposure code. A higher number means a
bigger change in lighting is required for the auto exposure to adjust.
The default value is 20.
•
Min & Max - Min is the minimum exposure NetCam will expose
images at (default is 0). The default value is the recommended
value. Max is the maximum exposure NetCam will expose images
at (default is 12500, 1/5 second). If your image looks noisy during
low light conditions, you can decrease the max exposure value.
Fluorescent Sync
If NetCam is imaging in an area lit by fluorescent lighting, enabling the
appropriate frequency (60Hz for US) will prevent NetCam from producing a
change in brightness or color balance that often accompanies imaging under
fluorescent lights. For outdoor shots (any other non fluorescent lighting
condition), set to off. The default value is off.
Manual Exposure
Enabling Manual Exposure causes NetCam to expose images at
the value placed in the Exposure field. Keep in mind that using manual
exposure is not advised for outdoor imaging, since the light conditions are
constantly changing. You may opt to use manual exposure indoors if your
lighting conditions do not change. Here are some sample values and their
fractional equivalents:

Exposure Grid
When Auto Exposure is enabled, NetCam adjusts the exposure of the
image based on the average brightness of the pixels located in the selected
regions in the Exposure Grid. If you want NetCam to determine the exposure
based on only the sky, you would select the squares that apply to the sky
NetCam

Download from Www.Somanuals.com. All Manuals Search And Download.
(click the View Grid button to see the grid over the image). Conversely, if
you’d like the exposure to be determined by the foreground, select only those
squares. This is comparable to the spot exposure on a traditional camera.
The default is the center 9 squares.
PROCESSING
Resolution
Resolution is the dimensional size of the NetCam image, measured
in pixels, horizontal by vertical. The maximum resolution of NetCam is
640x480 (1280x960 on NetCam MP) and the minimum is 96x80 color
(80x60 grayscale). The higher the resolution, the larger the picture appears
in your browser, and the longer it takes to download (and the longer it takes
for NetCam to process and create).
Default: 320x240 (640x480 on NetCam MP)
Tip: As with most digital cameras, NetCam achieves the highest quality and clearest
images at quarter resolution. This is due to the way color is calculated with
digital image sensors. The highest quality image on NetCam is 320x240. On
NetCam MP, the highest quality image is 640x480.
Saturation
This represents the amount of color in the image. The higher the number,
the more saturated the color.
Default: 1200
Gamma
Gamma correction is a post-processing enhancement that increases the
detail in shadowy areas of the image. The higher the value, the lighter the
shadows, at the expense of increased haziness.
Default: 1700
Intensity
Intensity is a post-processing enhancement that increases the brightness
of the image. This should not be confused with the brightness under the
auto exposure settings, which is a preprocessing setting. Intensity artificially
brightens the image after it’s already been exposed and color processed. In
most applications, the default of 1024 (no intensity change) is recommended.
If you have a dark lighting situation, you can experiment by increasing this
value. For example, 2048 doubles the brightness. You will most likely need
to adjust the Auto Exposure Brightness to counter balance the effect (to
prevent images that appear overexposed).
Default: 1024
Page 14
NetCam
Download from Www.Somanuals.com. All Manuals Search And Download.
Haze
Haze is a factory setting and should normally not be changed.
Default: 10
JPEG Quality
The JPEG Quality is a balance between lossy image compression
and image quality. The higher the number, the less compression artifacts
in the image, but the bigger the file size. A value higher than 90 is not
recommended, as it greatly increases the file size with very little
noticeable difference in image quality.
Default: 70
Sharpen
When enabled, a software sharpening is performed on the live image.
For the best image quality, sharpen should be on.
Default: On
Auto Color Balance
Enabling Auto Color Balance causes NetCam to automatically adjust
the color balance of the image, based on the content of the image. In most
situations, you will want Auto Color Balance enabled. You can skew the
red, green and blue values if needed.
Default: On
Manual Color Balance
Enabling Manual Color Balance causes NetCam to use the manual Red,
Green and Blue values to set the color balance of the image. You may want
use manual color balance if you have a fixed lighting situation.
R - This represents the amount of red in the image.
G - This represents the amount of green in the image.
B - This represents the amount of blue in the image.
Note: As a starting point for setting manual color balance values,
enable Auto Color Balance and place the current R, G, B values in the
image overlay.
Sample string: Red: $r Green: $g Blue: $b
Once you see the current values of the image, you can place those in the R,
G, B settings and have a manually balanced image.

Path/File
This field combines two elements, the image filename, preceded by an
optional path or directory. Consult with your hosting company to determine
if you need to specify a path. If you don’t, you simply put the desired name
of the image file here.
Example Without Path: netcam.jpg
Example With Path: /html/images/netcam.jpg
Advanced Fields
Rotating Archive
If enabled, NetCam will use a renaming scheme to store the current
10 images on your server. A hyphen, followed by the archive number
(0-9) is automatically appended to the end of the filenames.
Default: Off
Passive Mode
If NetCam is behind a proxy server, enable passive mode. If you are
unsure if you need passive mode, it is usually safe to enable it anyway.
Default: On
Timeout
If the FTP transfer is unsuccessful, Netcam will abort and re-initiate
the process after the specified amount of seconds.
Default: 120
Delete Before Rename
NetCam employs a file renaming scheme, which greatly reduces the
possibility of file collisions between NetCam uploading an image and view-
ers downloading the image. The image is uploaded with a .tmpextension.
Once uploaded the tmp file is renamed without the .tmpextension. Certain
FTP/Web servers do not allow a file to be renamed to a filename that already
exists. To get around this problem, enable Delete Before Rename.
Default: Off
IIS 4.0
Some FTP servers lock a file when a file with the same filename is
constantly uploaded and renamed. If you have problems seeing your image
update on your web site, try enabling the IIS 4.0 option. This option is only
valid if Delete Before Rename (above) is also enabled.
Default: Off
NetCam

Secondary Path/File
NetCam can optionally upload the image with a separate path and/or
filename from the Path/File above. This provides a very convenient way
to archive images on your server while still maintaining a statically named
live image. One way to do this is to include date/time markup characters
as part of the filename. The current upload time of the image will become
the filename.
For example, the filename %Y-%m%d-%H%M%S.jpgautomatically
translates to 2006-04-15-153015.jpg if the date and time of the
upload is April 15, 2006 at 3:30:15 PM.
Tip: For a complete list of Date/Time markup characters, click the Help button on
the Overlay page.
Example Without Path:
netcam-%Y-%m%d-%H%M%S.jpg
Example With Path:
public_html/netcam-%Y-%m%d-%H%M%S.jpg
Only the characters beginning with the percentage symbol (%) are valid.
It not advisable to use date/time characters that insert / \ : or space
characters, as this can confuse the FTP/Web server.
Current IP Link Path/File
If NetCam is using an external modem to dial out to an ISP, NetCam will
most likely be assigned a different IP address every time it connects. This
makes it next to impossible to access the camera directly from a browser
since its IP address is not known. To eliminate this problem, NetCam can
upload a small web page every time an image is uploaded. The web page
contains the current IPaddress of the camera so you can configure the camera
remotely. Clear this field if you don’t want this file to be uploaded.
Default: ip.html
Schedule
Scheduling tells NetCam when and how often to FTP images to your
server.
Delay
This tells NetCam to delay a specified number of seconds between
FTP image uploads. The speed at which NetCam can upload varies on the
image resolution, amount of JPEG compression, Internet connection and
network congestion.

Keep in mind that the overhead of FTP doesn’t allow for the same
update rates that you see when accessing NetCam directly with a browser. It
is safe to say that FTP restricts 320x240 uploads to once every 3-6 seconds,
even on a DSL or cable connection. 640x480 images will probably not
upload faster than once every 10-15 seconds.
Default: 30
Upload Window
NetCam can upload images 24 hours a day, seven days a week, or you
can set whatever time window and days of the week you like. Use military
time for the beginning and ending window times.
Example: You can configure NetCam to only upload Between 07:30
and 18:30 only on Mon, Tue, Wed, Thu and Fri
How do I display the live image on my web site?
The simplest way to add the live image on one of your web pages is
with the image tag: <img src=”netcam.jpg”>
To see the current live image, the visitor would have to hit the refresh
button. This reloads the web page and will display the current live image,
assuming a new image has uploaded already.
You can add a meta tag to the <head> section of your web page
that tells the browser to refresh the web page at specified interval:
<meta http-equiv=”refresh” content=”30”>
If you prefer a slicker solution that doesn’t require refreshing the whole
page and visibly redrawing the live image, StarDot provides a free Java
applet. You can download the Capture Client Java applet and instructions
here:

3.6 Applet Properties
TheApplet/Web Properties page contains information for customizing
the NetCam image-viewing Java applet. After making changes, click the
Apply button to save the settings in the camera.
IMAGE VIEWER JAVA APPLET
The live images on the main NetCam web page are presented with the
aid of a Java applet called Capture Client. This allows for smooth transitions
between image frames. Options include the ability to add a countdown status
bar and the ability to change the click URL.
Size
If the NetCam image is 320x240 and the size is 100%, the applet will
display the image at its original size, in this case 320x240. If the size is
50%, the image will display at half size, in this case 160x120. If the size is
200%, the image display at double size, in this case 640x480. Keep in mind
that the JPEG image is still the size specified in the Image Properties page;
the applet resize option simply reduces or stretches the original image. In
most cases, you would leave it at 100% (no resize).
Default: 100%
Delay
The Java applet will delay for this amount of time before attempting
to fetch another live image. The time is measured in milliseconds (1000
ms = 1 second).
Image-Click URL
When a viewer clicks on the live image, their browser will go to the
URL (web address) contained here.

Status Bar
The applet contains an optional status bar displayed in the browser
status bar or at the bottom of the applet.
Status Text
This is the text that is displayed in the applet status bar (if enabled).
Default String: Reload in %s seconds
Status Text Color
This is the color of the text that is displayed in the applet status bar (if
applet status bar is enabled). The color is defined in the HTML standard of
3 numbers for RGB. Format: RRGGBB (RR=red, GG=green, BB=blue, all
values hexadecimal 00-FF).
Default: ffffff
Status Bar Color
This is the color of the background that is displayed in the applet status
bar (if applet status bar is enabled). The color is defined in the HTML

3.7 Date/Time Properties
The Date/Time Properties allow you to set the date and time in NetCam.
After making changes, click the Apply button to save the settings in the
camera.
Setting the Date and Time
Automatic vs. Manual - For the most accurate date & time, having
NetCam automatically synchronize with a network time server is
recommended.
Automatic Time Set
WhenAutomatic time synchronization is enabled, NetCam will query
a network time server and synchronize the camera’s date and time, usually
accurate to within seconds or less. This will happen every time the camera
is powered on or rebooted, provided NetCam is connected to the Internet
or a network with a time server.
•
Time Server - The name (or IP address) of a time server is entered
here. Some popular ones include:
time.nist.gov
tock.usno.navy.mil
ns.arc.nasa.gov
Note: While these time servers have proved reliable over the years,
there is no guarantee that they will always be available to the public.
Manual Time Set
If you don’t have access to a time server, you may opt to manually
set NetCam’s clock. You can do this in one of two ways. Using the Sync
button, you can synchronize NetCam’s clock to your PC’s clock. You may

also manually modify the time and date in the Date/Time box. In either case,
be sure to hit the Apply button after you’ve set the time.
Note: When using Internet Explorer, the Date/Time page may disappear after
clicking the Apply button. If this happens, click the refresh button twice.
TIME ZONE
NetCam integrates your current time zone into the time/date string and
can even automatically adjust for daylight savings time. Type in the time
zone code from the list on this page. If your time zone is not listed, enter
your abbreviated time zone followed by the number of hours you are behind
GMT (if you’re ahead of GMT, add the “-” character before the value).

3.8 Network Properties
The Network Properties page contains all the IP configuration
information for setting up NetCam on a network. After making changes,
click the Apply button to save the settings in the camera.
Ethernet
If your network is Ethernet-based (LAN, cable modem, DSL), use the
NET port on the back of NetCam to access the camera. The first step to
network access is assigning NetCam an IP address. There are two ways in
which this can be done: automatically (DHCP) or manually.
IP Assignment
DHCP
By default, NetCam comes up in DHCP mode, meaning that it probes
the network for a DHCP server. If there is a DHCP server on the network,
NetCam is automatically assigned an IPaddress, subnet mask, gateway, and
name servers. No manual configuration is needed. One negative of DHCP
mode is not knowing which IP address NetCam was given. Use the StarDot
Tools software to find DHCP-assigned NetCams on your local network.
Manual
If you’d like to manually assign NetCam an IP address, set NetCam to
Manual IP Assignment and provide the following information:
•
IP Address - The IP address you’d like to assign the camera.
Consult your network administrator to determine which IP address
Page 28
NetCam
Download from Www.Somanuals.com. All Manuals Search And Download.
to use. If you are setting up NetCam behind a residential gateway or
cable/DSL router, your IP address will probably be something similar
to 192.168.1.5.
•
Subnet Mask - Find out your netmask from your network admin-
istrator. If you’re on a private network, your netmask will almost always be
255.255.255.0.
•
MAC Address - This is the factory-set Ethernet address of
the camera. It also serves as the Camera ID (serial number). It cannot be
changed.
Network
Hostname
Alphanumeric name of NetCam that can get linked to NetCam’s IP
address. This is disabled if DHCP is enabled.
Default: netcam
Gateway
In most cases, this is a machine name or IP address that serves as a
gateway to the Internet. If NetCam is on a private network behind a router/
gateway, you would enter the IP address of the router/gateway. This is
disabled if DHCP is enabled.
Domain Name Servers (DNS)
Domain name server IPaddress. This is critical if your FTPserver and/or
time server is entered as a domain name and not an IP address. Check with
your ISP to determine your name servers (you can list up to three). This is
disabled if DHCP is enabled.
Web Server Port
In most situations you will want to leave the web server port at its default
value of 80. The only situation that calls for changing the port number is if
you’re hosting one or more NetCams behind a residential router/gateway
that supports port forwarding. This allows you to access multiple NetCams
behind a single public IP address.
Example: Assign NetCam a web server port of 8085. In your router, under the port
forwarding section, route port 8085 to NetCam’s IP address.
Use caution when changing the web server port number. If it’s any-
thing but 80, you will need to add <:port number>to the end of the
browsing to NetCam.
Default: 80

3.9 Dial-Out Properties
The Dial-Out Properties page contains all the ISPdial-up configuration
information for setting up NetCam on a dial-up modem. After making
changes, click the Apply button to save the settings in the camera.
Internet Dial-Out Connection (PPP)
If NetCam’s primary connection to the Internet will be a dial-up modem
connection to the Internet, enter your ISP(Internet Service Provider) account
information here.
Check this option on if you’d like NetCam to use an external modem
to dial the Internet.
Baud Rate
This represents the speed or baud rate at which NetCam will
communicate with the external modem. For most dial-up accounts, a baud
rate of 38400 or 19200 works best.
Default: 38400
Initialization String
This is a string that configures your modem before dialing the Internet.
The default string works fine in most cases.
Default: AT
Phone Number
The phone number of the ISP (Internet Service Provider). You can
embed special characters in the phone number.
Page 30
NetCam

,= pause one second
#= same as # button on phone
*= same as * button on phone
Timeout
NetCam will attempt to dial up the ISP for the specified number of
seconds. If NetCam is unable to connect during this time period, it will
stop and start over again.
Default: 180
Username
The username or login assigned to you by your ISP.
Password
The password assigned to you by your ISP.
Default Connection
Enabling this option makes the ISP dial-out connection NetCam’s
default connection to the Internet.
Default: On
Always Up
If enabled, NetCam will attempt to stay continuously connected to
the Internet. If disconnected, it will automatically attempt to reconnect. If
NetCam is configured to upload images to a server via FTP, it is not necessary
to enable this option; NetCam will automatically attempt to dial into the
Internet when an image is scheduled to upload if dial-out is enabled. If your
NetCam is set to FTP images, it is recommended that you do not enable this
option but rather let the FTP upload schedule keep the camera online.
Default: Off
Send CR After Login
This advanced ISPoption tells NetCam to send a CR (Carriage Return)
after logging in. Most ISP’s do not require this.
Default: Off
Shell Login
This advanced ISP option tells NetCam to perform a shell login. Most
ISP’s do not require this.
Default: Off

3.10 Security Properties
The Security properties page contains user/password information for
securing NetCam from unwanted visitors.
NetCam Users
NetCam has its own multi-user capable, password protected operating
system. By default, the live images can be viewed by anyone and only the
configuration pages are password protected. However, these options can
be changed.
admin - The admin user has configuration and viewing rights. It is
strongly recommended that you change the default password (initially
“admin”) to something else. This will prevent anonymous users
from logging into the camera and making changes. It is important to
choose your password carefully. Pick something that cannot be easily
guessed. The password can be a combination of alpha and numeric
characters, upper and lowercase (maximum 8 characters).
Tip: Use a password that cannot be easily guessed (maximum 8 characters).
viewer - The viewer user only has viewing rights (this user cannot
access the configuration menus). By default, the viewer user has no
password. This allows anyone to view the images on the camera
without being prompted for a password. If you want to block public
access to the live image, you will need to change the password for
the viewer user.
To modify the password of an existing user, click on the user name
and then type in a new password in the password field (retype it in the
verify password field). Then click the Add/Modify button.

Adding a New User
To add a user to the Users list, type in the desired username in the
Name field. Type and retype a password in the Password fields. Click the
Add/Modify button. New users will only have viewing rights; only the
admin user can make configuration changes in the camera.
Deleting a User
To remove a user from the Users list, click on the desired username and
click on the Remove button. Note: The default users, admin and viewer,
cannot be removed.
3.11 Advanced Menu
The advanced menu is a hidden menu that allows you to configure
some advanced features inside NetCam such as the Weather Station and
Dynamic DNS support.
In order to access the advanced menu you will need
to click the small linked character to the right of the
version number, under the Help, Apply and Cancel
buttons.
Note: The advanced menu provides access to all of the configuration
files in NetCam. We recommend that you do not edit these files unless
you are well versed in Linux and NetCam camera settings.
On the upper left of the advanced menu are option are links to options such
as the optional weather station and dynamic DNS support.
NetCam

TZO Dynamic DNS
If NetCam is behind a DSL or cable modem connection and the public
IP address changes, you can use tzo.com as a dynamic DNS service. This
maps your dynamic (i.e. always changing) IP address to a static hostname
of your choice (i.e. yourcompany.stardotcams.com or yourname.remotecam.
com).
Why is knowing your public IP address valuable? If your router is
configured to “port forward” port 80 to NetCam’s local IP address, you can
browse to NetCam directly from anywhere on the Internet. This is useful for
viewing the camera live and making configuration changes from a remote
location. For information on configuring port forwarding on a router, visit
signed up, enter the appropriate information in either NetCam or your router
(if it supports DDNS).
Weather Station
StarDot offers an optional mini weather station (AUX-WX2) that plugs
into the back of NetCam. It’s a great way to capture and display the current
temperature, humidity and barometric pressure. To view the weather data,
add one or more of the markup tags in your overlay text:
${C}
${F}
${HUM}
${MB}
${HGIN}
${HGMM}
Degrees in Celsius
Degrees in Fahrenheit
Humidity Percentage
Millibars
Inches of Mercury
Millimeters of Mercury
Example: ${F}°F ${HUM}%% ${HGIN} in.

Chapter 4 Imaging Tips
As is the case with any camera, whether digital or film-based, steps can
be taken that will great improve image quality. NetCam is no exception to
this rule. The following tips will help you achieve the best possible images
with NetCam.
4.1 Lighting
Lighting is the single most important factor in quality photography.
Proper lighting makes the difference between an amateur-looking snapshot
and a professional-looking image. Lighting for a live still camera such as
NetCam can divided into two categories: outdoor and indoor.
Outdoor Lighting
In most outdoor imaging situations, you do not have much control
over the lighting since most of your lighting obviously comes from the sun.
However, you do have control over the lens settings and the positioning of
NetCam. If you have a motorized zoom lens, you can ignore the iris section,
since the iris is controlled automatically by NetCam.
The Iris
The first thing to consider with outdoor lighting is the lens iris. The
iris is an adjustable ring that controls the size of an aperture inside the lens
barrel. The smaller the iris, the less light that reaches the CCD sensor. The
bigger the iris, the more light that reaches the CCD sensor. It is critical that
NetCam’s lens iris is set properly when pointing NetCam outdoors. The
reason for this is twofold -- it provides much better image quality and it
prevents permanent damage to the CCD sensor. If your lens has iris markings
on it, adjust the iris to ƒ16 (the larger the ƒ-stop, the smaller the iris). If your
lens does not have numerical iris markings, look into the lens and visually
watch the aperture change size as you turn the iris ring. You want to adjust
the aperture until it is roughly the size of a pinhole.
Precisely Setting the Iris
•
With NetCam in its permanent outdoor position, set the iris to the
size of a pinhole.
•
•
In the Overlay Properties page, add $eto the Text string.
Monitor the live image. In bright daylight, the exposure should read
between 100 and 500.
•
•
If the exposure is less than 100, close the iris more. If the exposure is
more than 500, try opening the iris slightly.
Note: Make sure “Auto Exposure” is enabled. The iris setting is a
one-time procedure.
NetCam

The Sun
If possible, aim NetCam so that it never points directly into the sun. The
best direction is north or south. If you must point the camera in a western or
eastern direction, try to get as little sky as possible in the image. What you
want to avoid is direct sunlight -- as with any camera, or your eyes for that
matter, looking into the sun produces some of the worst images. It can also
damage the CCD sensor over time, even with the iris set properly.
There are certain imaging factors that are not controllable. Depending
on where the sun travels in relation to the camera, you may find that images
look better in the morning than the afternoon or vice versa. This is just the
reality of lighting and is normal.
The Sky, Backlighting and Dynamic Range
One thing you can do to control the quality of your images is to reduce
the likelihood of backlighting. Backlighting occurs when the background
of an image is significantly brighter than the foreground. One example is
a group of buildings in front of a bright sky. Depending on the difference
in brightness between the buildings and the sky, the buildings can become
a dark silhouette against the sky. Most cameras, as well as the human eye,
are unable to capture details in both the dark foreground and the bright
background at the same time. Dynamic range is the term used to describe
the amount of detail a camera is able to capture in both dark and light areas
at the same time. NetCam has great dynamic range, but as is the case with
most cameras, it has its limits.
Here are a few suggestions for reducing backlighting:
•
•
•
Point NetCam so little or no sky is visible in the image.
If you want sky in the image, point NetCam to the north (or south)
Use gamma correction option on the Image Properties page to
increase the details in shadowy areas of the image.
Indoor Lighting
The biggest advantage that indoor lighting offers is control. Unlike
outdoor lighting, there is no need to worry about a travelling light source
or a strongly backlit sky. However, that doesn’t mean indoor lighting does
not have its challenges. Here are some suggestions for improving indoor
imaging.
•
•
If light is limited, open the lens iris all the way.
Avoid pointing the camera at regions with white walls in the
background as this may produce an undesired backlighting effect.
•
•
Avoid pointing the camera toward a window.
If possible, avoid mixed light sources. For example, a room with
Page 36
NetCam
Download from Www.Somanuals.com. All Manuals Search And Download.
both fluorescent and halogen lights will illuminate the room with
different color temperatures, which will be visible in the NetCam
images.
4.2 Image Processing Options
The images produced by NetCam are processed and compressed inside
the camera. Many options that affect the quality of the image are available
on the Image Properties Page -- the important ones are listed here (for a
complete list, see Chapter 2.1).
Brightness - This controls how the bright the auto exposure will adjust
the image. When auto exposure is enabled (which it should be,
especially when doing outdoor imaging), this is the main control you
will need to adjust to increase or decrease the overall brightness of
the live images. If your images are coming out dark during daylight
(or indoor lighting), increase this value.
Saturation - This value represents the amount of color in the image. The
higher the number, the more the saturated the colors become. The
default value works well in most cases. If you do want more color
saturation, increasing the number from its default of 1200 to 1300
should do the trick. Anything higher may start to produce undesired
color effects.
Gamma - This adjusts the amount of detail visible in shadowy areas, at
the expense of increased haziness. Try increasing the default value of
1700 to 1800 to see more details in dark areas. Or if you want more
contrast, reduce it to between 1000 and 1500.
Sharpen - For the best quality images, this should always be left on.
JPEG Quality - The default value of 70 works well in most cases. The
compression artifacts are minimal and the file size small. While
increasing the quality will result in a slightly clearer image (less
JPEG compression artifacts), the significantly increased file size
hardly makes it worthwhile, especially when the quality is set to
90 or higher. Conversely, if you’d like images to download/upload
faster for viewers with dial-up Internet connections, you can reduce
the JPEG quality which decreases the file size. A value of 50 still
results in good looking images at a very small file size.

Chapter 5 NetCam Lenses
The Focus Ring
NetCam ships with a pre-focused lens. Most lenses available for
NetCam also have a focus ring which allows you to focus the lens for a
closer subject. The focus ring may be marked in meters:
0.2m -- 0.3 -- 0.4 -- 0.5 -- 1.0 -- oo
The oo stands for infinity. When NetCam leaves the factory, the infin-
ity setting is back-focused for infinity. Turning the focus ring to 0.5 meters
will yield a focus of half a meter. Turning it back to the infinity symbol will
yield an infinite focus again.
Some lenses will not have the numerical markings -- they may be
marked only with “near” and “far”. The “far” setting is infinity and the
“near” setting is the closest the lens will be able to focus, which varies
from lens to lens.
The Iris Ring
Most lenses available for NetCam come with a manually adjustable
iris ring. In indoor lighting situations, you will usually want the iris open
to its fullest position. In outdoor lighting, you will almost always want the
iris set to its smallest position (ƒ16 or smaller, pinhole-sized). The iris ring
is usually marked in ƒ-stops:
1.3 -- 4 -- 8 -- 16 -- C
The C stands for closed. In this example, the 16 setting is the smallest
marked iris opening and 1.3 is the largest. You can set the iris to settings in
between the marked numbers (setting it between 16 and C would result in
a setting closer to ƒ22, which is even smaller than ƒ16).
Some lenses do not contain numerical iris markings, but will be marked
with “open” and “close”. You will need to look in the lens to see the size
of the iris when placing NetCam outdoors. Adjust the iris ring until the iris
opening or aperture is the roughly size of a pinhole. We strongly recommend
you tune the iris by following the instructions in section 4.1.
Changing Lenses
Change lenses usually requires a back focus adjustment of the new lens.
Back focus is the adjustment of the chrome ring that the lens is screwed
into. Follow these steps when replacing a lens.
1.
2.
Unscrew the original lens from the chrome back ring and com-
pletely remove it.
Determine if your lens is C-Mount or CS-Mount. If you ordered
Page 38
NetCam

it from StarDot, it will be noted on the packaging.
The only difference between a C-Mount lens and CS-Mount lens is
the C-Mount lens requires a 5mm spacer between the lens and the
chrome back-focus ring (the spacer is included with the standard
8mm C-Mount lens that ships with NetCam).
If your lens is CS-Mount, you do not need to use the included 5mm
spacer. If your lens is C-Mount, unscrew the black 5mm spacer
from the back of the 8mm lens and screw it onto the back of the
C-Mount lens you will be installing on NetCam.
3.
Screw the new lens (with attached spacer if the lens is C-Mount)
into the chrome back focus ring on NetCam. Continue turning until
the lens is a securely attached.
4.
5.
Set the lens focus ring is set to the infinity setting (oo).
Set the lens iris all the way open if indoors or to a pinhole size
(ƒ16) if outdoors.
6.
Use a web browser to view the camera’s live image. For the rough
focus, you may want to select a low resolution like 160x120 so the
images update faster.
7.
8.
Use the included Allen or hex wrench to loosen the back focus set
screw on the bottom and/or top of the camera.
While watching the live image turn the entire lens assembly (lens,
optional spacer, and chrome back focus ring) counterclockwise
by 1/2 turn. Make sure the individual iris and focus rings do not
get turned out of position. Focus must be in the infinity position
and the iris all the way open for indoor lighting or set to a pinhole
size for outdoor lighting.
9.
Wait a few seconds for the live image to catch up to the focus change
and see if the image gets clearer or blurrier. If it looks sharper,
continue turning in the same direction until you get a rough focus.
If the image looks blurrier, try turning one full turn clockwise.
10.
11.
Once you get a rough focus with the low-res image, set the resolu-
tion to 320x240 or 640x480 for your fine focus.
Focus on something across the room (or in distance outdoors)
that has detail (i.e. lettering, a contrast-heavy pattern, etc.). Once
you get a sharp focus, use the Allen or hex wrench to tighten the
back-focus set screw. Do not overtighten.
Tip:
The key to focusing a lens on NetCam is to wait for at least three live
images to update before evaluating the change.

Troubleshooting Guide
The StarDot Tools software does not list NetCam on my local network and/or
is not accessible via its IP address.
1. Double check all cable connections and make sure NetCam’s network cable
is plugged into an active Ethernet hub, switch or router. Make sure NetCam’s
power LED is on (amber on boot-up, then green).
2. Connect NetCam to a PC’s serial port with the included null modem
cable to verify network settings with the StarDot Tools software.
NetCam is slow to respond on a web browser.
1. If you have dial-up Internet connection, this may be normal.
2. Increase the applet refresh time, especially if the image resolution is set to
the highest value. Try a value like 2000 or 3000 (2 or 3 seconds).
3. Set the JPEG quality to 70 or below. The higher the JPEG quality, the bigger
the image file size, with very little improvement in image quality.
Images are not uploading to FTP server.
1. Double check all settings including hostname, username, password and
path by using third party FTP client software (the command prompt FTP
in Windows is a good test).
2. Try using an IPaddress in the hostname, or double check your DNS settings.
For dial-up NetCam, do not use an IP address, use a hostname.
3. Try turning on the advanced FTPoptions “Delete Before Rename” and “IIS
4.0”
4. Telnet to NetCam and type cd /etc/configand press Enter. Type ftp-
script ftp.scrand press Enter. Watch the results for errors.
