GeoVision ( No picture White Screen)

We recently had a customer that was having issues getting a picture on his cameras, he was getting a white screen for each of his cameras and when he unplugged the camera it read video loss on the on screen display.

Solution: First stop all monitoring, then go into Configuration/AV Setting/Video Source now make sure the video standard is set to NTSC For American video standard and PAL for European Video Standard.
