4-1 Power supply
Connect 12V
±
IV DC from an external power supply.
Use a stable power supply without ripple and noise.
4-2 To protect CCD(sensor)
1) Do not touch the glass surface of the sensor to avoid dirt and scratches.
2) If the glass surface of the sensor should become dusty or dirty, wipe off dust or dirt
carefully with a cotton-tipped applicator. Never use dry cloth or paper. The surface may
be scratched and further the sensor may be damaged by static electricity.
3) Be sure to mount a lens or the supplied mount cap on the camera to protect the sensor
from dust.
4-3 To protect camera
1) Do not use or store the camera under direct sunlight, in environments exposed to rain,
or snow, or at a place exposed to flammable or corrosive gas.
2) The camera operates in the temperature range between -10 and 50
°
C.
If the camera is used or left at a high temperature(40°C or more)for hours, the life of
the camera may be shortened.
When using the camera continuously for hours, avoid using the camera in areas of high
temperature or high humidity.
3) Do not drop the camera. Do not apply strong shock or vibration to the camera.
4) Before connecting or disconnecting a connector, turn off the camera. Be sure to hold
the connector body to connect or disconnect the connector.
4-4 Arrangement of camera
When several cameras are installed very close with each other, the cameras may interfere with
each other to cause noise. Install the cameras as far as possible from each other or operate the
cameras by an external sync signal.
4-5 Phenomena inherent to CCD imaging device
Following are phenomena inherent to a CCD imaging device, and are not defects.
1) 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.
2) 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
