1. No picture after providing power
. Maybe the power supply has voltage abnormity, please check the
power
supply voltage and pole whether exactitude.
. Please check all the connecting cable and monitors whether be con-
nected
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 be-
tween the
camera and the fluorescent lamps can improve it.
. Use power supply external sync. camera can solve it.
