Hitachi BE IR31 User Manual

BE-IR30 / 31  
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.  
11-1 AGC on / off  
Factory setting is AGC off (fixed gain). If necessary in the application, AGC can be set to on.  
When the AGC is off, the gain can be changed by turning RV201.
