I connect the general analog camera to the device, there is no video output.

There are following possibilities:

  • Check camera power supplying, data cable connection and etc. There might not be sufficient power from the power source. You can use a voltage tester if you have one on hand.
  • Check the length of cable run. Refer to the specifications for the limitations on the cable length.
  • This series device does not support the analog camera of all brands. Please make sure the device supports general standard definition analog camera.
  • If there is no video, check the coax connection. Unsecured faulty connections will result in no video or intermittent video.
