requirement. Avoid using the camera at too high
or too low temperatures. The operating temperature is
-

℃
. (Recommendatory operating temperature is
-
10~+50
℃
.)
Never make the camera face the sun or bright object. Other-
wise, it will damage the CCD
Do not mount the camera near by the radiator or heater.
1. No Picture after providing power
. May be the power supply voltage abnormity, please check the power
supply voltage and pole whether exactitude
. Please check all the connecting cable and monitors whether be connected
correctly or not
2. The picture level direction have flowing interference ripples
. May be caused by the power supply AC ripples, it need filter the wave of the
power supply
. Check the monitor and peripheral equipments used.
!
3. The picture background color changes continuously
!!!!
. The fluorescent lamp’s electromagnetic field cause color roll. This is proper
phenomenon of the cameras.
. Reduce the fluorescent lamp numbers or increase the distance between the
camera and the fluorescent lamps can improve it.
. Use power supply external sync. camera can solve it.
4. The picture smear too mass
. The power supply’s voltage unstable
. Connecting cables not connect correctly or have high impedance.
