Hi
Just wanted some advise on basic instalation on cctv cameras which I'm connecting to the tv to use as monitor.
The camera I'm looking at is a SENTIENT WEATHERPROOF DAY/NIGHT CCTV SECURITY CAMERA Wireless with 15 Metre night range and audio.
I was told I can connected it to a tv channel, but if I use 2 do I have an alternative not to use 2 channels? Are these cameras of reasonable quality for night vision.
