TROUBLE AND SOLUTION
1. No Picture after providing power
. May be the power supply voltage abnormity, please check the power supply voltage and pole whether exac-
titude.
. 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.
Notes:
- The power supply must through safe attestation. Its output voltage current voltage polarity and operating
temperature must match the camera’s requirement.
- When using the camera in the thunderbolt condition,please note to mount Anti-thunder device or put off the
power supply plug and cable.
- In order to capture high quality pictures, the power supply’s cable and video output cable should not be too
long.
- Please note the camera’s operating temperature and its using environment requirement. Avoid using the ca-
mera at too high or too low temperatures. The operating temperature is -10° -50°. (Recommendatory ope-
rating temperature is -5° - -40*.)
- Never make the camera face the sun or bright object. Otherwise, it will damage the CCD.
- Do not mount the camera near by the radiator or heater.
