Audio Cctv

How do I power a cctv camera?
I want to get some cameras for my house but the set up has lost me. The a/v cables for them have power as well as the audio and video. How does this hook up to a vcr, or do I need something else?
I am assuming the cameras you are getting come with a power supply and cabling?
You mount the each of the cameras in the location you choose and run the cabling back to the recording point. For power, each camera can either be powered separately or you can buy a specialized power supply to power all of the cameras.
Audio and video gets a bit tricky if you are just using a consumer type vcr since that type only has one video and audio input. You could buy one vcr per camera but that gets expensive if you have a lot of cameras.
You can buy a multiplexer but I think that will only do video and not audio.

You can buy multi-channel dvr's. Some are video only while others are video and audio

If I were you I would also consider pre-packaged systems.
