Power supply
Connect a 12V DC voltage (11 to 13V) from an external regulated DC power supply.
Use a stable power supply without ripple and noise.
Prior to turning on the power switch , check that the polarities of the power cable are correct ,
referring to the connection diagram
To protect CCD (sensor)
Do not touch the glass surface of the CCD sensor to avoid deterioration in picture quality due to dirt
and scratches.
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
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.
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.
Do not drop the camera. Do not apply strong shock or vibration to the camera.
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
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
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.
