I use a CCTV camera in a water proof housing to record inspections of water wells casings. I've been able to use a CCTV camera with a camcorder in the past to record what I'm seeing on the LCD screen. Presently I've test the CCTV camera with a car rear view backup monitor and even tried a TV AV output - I get a visual on the screen of the camcorder no problem with both. When I connect this new CCTV camera with my camcorder in the same A/V port as I've done in the past nothing comes up on the TRV 900 camcorder's LCD screen. I've checked and double checked the wiring but can't get it to work. It's NTSC compatible - I've tried everything with the camcorder settings but nothing. Am I missing something?
