CCTV Tester  
2. Overview  
2.1 Introduction  
The CCTV Tester tests camera video output, signal strength, and PTZ functions. It  
also acts as a video pattern generator, cable mapper, and digital multimeter.  
2.2 Features  
A. Camera video testing (Visual). See page 16. Test a CCTV camera’s video  
output visually by displaying it on the tester’s color LCD screen or loop the signal  
through to a video monitor.  
B. Camera video testing (Signal strength). See page 17. Perform a signal  
attenuation test with the touch of a button. The video signal’s voltage (max and  
average Vpp) is displayed as sync voltage. Perfect for detecting weak signals. Also  
measures sync voltage.  
C. Camera motion testing (PTZ). See page 17. Test a PTZ camera’s pan, tilt, and  
zoom directly from the tester’s keypad. Complete with preset settings and speed  
adjustment. Supports RS-232, RS-422 simplex and RS-485 connections. Baud  
rates of 2400, 4800, 9600 and 19,200. RS-485 protocol includes: Pelco D,P,  
Samsung, Panasonic, Molynx, and more.  
D. Monitor testing (Video signal generator). See page 15. Inspect monitors and  
DVRs by driving them with a known good video signal from the tester. It can  
output color bars and separate colors. The Camera Wizard only supports NTSC  
format.  
E. Keyboard testing (RS-485 serial data test). See page 20. Test the RS-485 data  
sent from a control device by displaying its hexadecimal data.  
F. Digital multimeter. See page 22. Detect AC/DC voltages and measure  
resistance using a built-in DMM. Useful in measuring and isolating circuit  
problems.  
G. Power to camera. See page 23. The tester can supply 12 VDC (200 mA) power  
to a CCTV camera. Use when no camera power supply is available.  
H. UTP (CAT5 or CAT6) cable test. See page 18. Test CAT5 or 6 cables for opens  
and shorts. Remote terminator included.

Figure 3-2. Quick test setup.  
A. Viewing a camera image: Follow diagram A to connect a CCTV camera (includ-  
ing PTZ control) to the tester. The cameras video output connects to the testers  
VIDEO IN BNC connector. The cameras PTZ control wires connect to testers  
RS-485/422 control block (using the terminal block/alligator clip adapter provided  
with the tester). Turn ON the tester and select menu item “2.” The cameras video  
will display on the tester screen. More detailed instructions follow in this manual.  
B. Connecting a monitor: Follow diagram B to connect a CCTV monitor to the  
tester. The testers VIDEO OUT BNC connects to the monitors video input connector.  
You can drive the monitor with the video signal generated by the tester (menu item  
#4, then TELE) or in “looped mode” with a cameras video connected to the testers  
VIDEO IN BNC (menu item #4, then WIDE). More detailed instructions follow in this  
manual.  
3.4 Main Menu (in order of appearance)  
3.4.1 Selection 1: System Setup: Display battery status, set auto-off time, and set  
up PTZ parameters to match your CCTV camera.  
NOTE: If you are not using the PTZ (pan/tilt/zoom) test feature, there is no need to  
set the PTZ parameters.  
ENTERING AND EXITING: Press “1” to enter the setup screen. Press “MENU” to  
return to the Main Menu. A typical configuration is as shown in Figure 3-3.

MODIFYING THE SETTINGS:  
ENTER SETUP MODE: Press “SET.” In this mode you 1) modify the PTZ settings  
(Protocol, Com, Rate and Speed) to match the camera you are testing and 2) set the  
battery saver turnoff time (when no activity).  
SELECT THE ITEM: Press the “UP and DOWN arrows” to blink the line you wish to  
modify. Battery status (% remaining) cannot be modified.  
ADJUST THE PARAMETER: Press the “UP/DOWN/RIGHT arrow.”  
SAVE/EXIT. Press the “LEFT arrow” to save the setting. Press the “LEFT arrow”  
again to stop the blinking. Exit by holding the “MENU key” to return to the Main  
Menu.  
NOTE: The CCTVTEST has 20 PTZ protocols and 17 speed settings (1 is the slowest  
and 16 is the fastest).  
3.4.2 Selection 2: Video, Signal Strength, and PTZ Test  
A. Display a camera’s video signal on the LCD and monitor:  
CONNECTION: Connect the camera to the tester as shown in Figure 3-1. The  
camera connects to the testers VIDEO IN jack.  
Display camera video: Press “2” on the keypad to turn ON the testers video and PTZ  
feature. The cameras video appears on the color LCD display. The cameras video  
will also appear on a monitor (if connected to the testers VIDEO OUT jack). Study  
the image for proper focus and viewing angle. Study the voltage readout (below)  
for proper amplitude. And use the testers PTZ feature (below) to control pan, tilt,  
and zoom.

Chapter 3: Operation  
Adjust LCD brightness: Use keys number 7 (BR+) and 9 (BR-) to adjust the LCD  
screens brightness.  
B. Measure signal strength (Vpp) and attenuation:  
Video signal strength (attenuation): With the tester displaying the video signal  
(see A), press the “1” (IRE) key. The following is displayed:  
MAX Vpp: The peak-to-peak amplitude of the video signal. The larger the video  
signal, the brighter the picture. 1 Vpp is minimum.  
AVERAGE Vpp: The average peak-to-peak amplitude of the video signal.  
SYNC SIGNAL: A cameras sync pulses synchronize the camera with the monitor.  
NO VIDEO: No signal, “No Video” will be displayed.  
Example of attenuation: If the Vpp at the camera is 1.25 Vpp, and the Vpp at the  
end of the cable is 1.15 V, the attenuation is 8%.  
C. Testing and controlling the camera motion (PTZ):  
Connection. Connect the camera to the tester as shown in Figure 3-2, diagram A.  
The cameras PTZ wires plug into the T+ and T- ports on the testers RS-422/485 jack  
(use the terminal block/alligator adapter).

3.5 Provide Power to a 12V Camera  
The tester can be used to provide power to a 12V camera.  
CONNECTION: Connect the cable (included) to the testers DC 12V OUTPUT”  
jack (on the left side of the tester). Connect the other end to the cameras 12-VDC  
power input jack. Use only with 12 VDC cameras (200 ma max.).  
WORKING TIME: The amount of time that the tester powers the camera depends  
on the cameras power consumption. If the camera draws less than 100 mA, the  
tester will power the camera for about four hours.  
MAXIMUM CURRENT/POWER: The maximum output current from the tester  
is 200 mA/2400 milliwatts.  
NOTES:  
1. The output voltage of tester is DC12V. Please only connect it to 12V cameras.  
2. Do not connect the testers DC12V output to the testers own 5-VDC input jack.  
This will damage the tester.
