    Horizontal Line Through Middle Of Image

    Hi, thanks for replying. My thoughts were power supply. I have tried 3 different 12v 2a power supplies but same problem every time. The length of cable is 30m, Annke brand. I have ordered a 12v 4a PSU to try.
  3. Hi, can anyone help me with this problem i have? In the image i have attached there is a faint horizontal static line going through the image. I have changed the BNC cable but that did not fix this issue. The camera is a Dahua HAC-HDBW2221RP-Z. This camera has a motorised zoom and when i use the zoom, the camera seems to turn off and back on. Not sure if these both issues are linked. Any help to solve this issue would be greatly appreciated.
