Note:

● Please note the camera’s operating temperature and its using

environment

requirement. Avoid using the camera at too high

or too low temperatures. The operating temperature is -30~

+60℃. (Recommendatory operating temperature is –10~

+50℃.)

● 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.

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 Colour changes continuously

. The fluorescent lamp’s electromagnetic field cause Colour 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 impr ove 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 cor rectly or have high impedance.

enclosure that may be of sufficient Magnitude to
a risk of electric shock to persons.

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.
