We have a problem with two Gv 1240 setups:
The problem starts with rolling white lines that go through several of the camera screens.
Then rolling gets worse then shakes and scrambles over a period of a couple of weeks, at this point it it barely viewable.
We have tied unpluging each camera and a block of cameras no success. we have unpluged all cameras and power. still no success. When all video and camera power is off we still have wavy and scrambled screen. It is not the monitor because the desktop icons to the side are not affected.
The setup is cat 5 with baluns from camera to video board, power supply leads to fuse box. Using a sony vaio 3.00 gh with 2 250 hd
Regarding the problem with Gv1240, there are three things I can think of.
The customer uses the video source of Pal standard. Please change back to NTSC from configure ->video source
Power not stable for camera.
Card has problem. Either clean the dust on the card or the card itself is bad.
