Infrared B/W Camera Module
Operation Guide
Please read this operation Guide carefully for proper operation, and keep it for future refernce.
1. Introduction
Thank you very much for your purchase of the Hitachi BE-IR30/31 Black and White Camera
Module.
Prior to using this camera , read this manual carefully.
2. General
The BE-IR30/31 is a monochrome camera module featuring sensitivity in the near infrared
spectrum using a 1/3-inch size CCD imaging device. Resolution is outstanding, while the very
small size provides optimum suitability for incorporation into equipment where space is limited.

NOTE
Auto electronic shutter
This is normally set to off at the factory.
If using a board lens (type B or C), the auto electronic shutter can be supplied from the factory at the on
setting. Since changing the setting is somewhat troublesome (requires tools and technical skill for
working with miniature parts) whenever possible, specify desired on or off setting at time of order.
Also note that certain types of lighting (e.g., fluorescent or mercury vapor) may cause flicker to appear on
the monitor screen due to effects of power line frequency.

5. Notes to users
‹ Power supply
z Connect a 9V DC voltage (8.5 to 9.5V) from an external regulated DC power supply.
z Use a stable power supply without ripple and noise.
z Prior to turning on the power switch , check that the polarities of the power cable are
correct , referring to the connection diagram (Page 11 , 12)
‹ To protect CCD (sensor)
z Do not touch the glass surface of the CCD sensor to avoid deterioration in picture
quality due to dirt and scratches.
z If the glass surface of the sensor should become dusty or dirty , remove dust or dirt
carefully with a cotton-tipped applicator. Do not wipe the surface with dry cloth or
paper tissue to avoid possible damage to the glass surface by static electricity.
‹ Protection of camera
z Do not use or store the camera under direct sunlight , at a place exposed to rain or
snow , or at a place where flammable or corrosive gas is present.
z When housing the camera in a camera case , use the utmost care regarding rise of
internal temperature.
When casing the camera , the temperature normally rises by 10 to 20℃ , compared
with the outside air temperature. The camera operates in the temperature range from
-5 to 45℃. If the camera is used or left in high temperature environment for hours ,
the life of the camera may be shortened.
z Do not drop the camera. Do not apply strong shock or vibration to the camera.
z Before connecting or disconnecting a connector , turn off the camera and be sure to
hold connector body to connect or disconnect the connector.
‹ Camera arrangement
z Mutual interference noise can occur if multiple cameras are arranged in close proximity.
Separate the cameras to the extent possible.
When camera units are installed directly into other equipment , external noise can
prevent a normal picture. In such cases , shield the camera units.
The camera can be damaged by static electricity. Use ample care when installing
and arranging.
‹ Auto electric shutter
z In regions using 50 Hz power line frequency , flicker can appear on the monitor screen
from light sources such as fluorescent or mercury. In such cases , release the auto
electronic shutter.

5. Notes to users
‹ Phenomena inherent to CCD imaging device
Following are phenomena inherent to a CCD imaging device , and not defects.
z Smear and blooming
When strong light (lamp , fluorescent lamp , reflected light , etc.) is shot , pale bands
are displayed vertically above and below the light.
In this case , change the angle of the camera so that such strong light does not enter
the camera through the lens.
z Fixed pattern noise
When the camera is operated in a high temperature , fixed pattern noise may appear
on the entire screen.
The higher the sensitivity of camera , the more this fixed pattern noise appears.
z Moire
When fine patterns are shot , moire may be displayed.
z The CE mark is required when exporting to Europe. Obtain the necessary
authorization for the customer’s system. Enclose the camera in a shielded case and
use shielded cable.

8. Installation
When installing the camera in a housing or unit of equipment, secure with two M2 screws
inserted into the 2.5 mm diameters holes of the SENS board base plate.
Two 2.5 mm Dia.
SENS board
1. Use the SENS board holds to install the camera. Avoid using only the Main board,
due to risk of damage to the board connector.
Notes :
2. Avoid unnecessary stress on the printed board when engaging and disengaging the
connectors.
3. The screws securing the base plate and SENS board protrude a maximum of 2 mm
from the base plate. Observe these screws do not contact the housing or installed
equipment.

11. Function setting and changes
When changing the function settings , perform the work with thorough care. Be sure to use
anti-static measures such as a grounding band. Also observe safety precautions when
soldering to avoid burn and fire hazards.
Hitachi Denshi assumes on liability for damage or injury resulting from such work.
Since the function setting can be provided at the time of shipment , consult a Hitachi Denshi
representative.
