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
BE-IR30 / 31 5
Power supply
zConnect a 9V DC voltage (8.5 to 9.5V) from an external regulated DC power supply.
zUse a stable power supply without ripple and noise.
zPrior 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)
zDo not touch the glass surface of the CCD sensor to avoid deterioration in picture
quality due to dirt and scratches.
zIf 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
zDo 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.
zWhen 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.
zDo not drop the camera. Do not apply strong shock or vibration to the camera.
zBefore connecting or disconnecting a connector , turn off the camera and be sure to
hold connector body to connect or disconnect the connector.
Camera arrangement
zMutual 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
zIn 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
BE-IR30 / 31 6
Phenomena inherent to CCD imaging device
Following are phenomena inherent to a CCD imaging device , and not defects.
zSmear 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.
zFixed 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.
zMoire
When fine patterns are shot , moire may be displayed.
zThe 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.
