was given 2 cctv cams today by my regional manager to help beef up the security, they were removed from a site in leeds a few weeks back and were working

engineer removed them, and chopped the wires without labeling them



i have had the cams out the housing and the only thing they have on them is

CAM3CCTVIR on the back

which i assume means there IR @ night, the wiring plugs into the cams with what looks like a din plug, i spread the end of the wires and found this



2 of them look suspiciously like thin coaxial style stuff to me (one is shielded)
i would assume red and black are power? but they look a little thin for 240v, i tried hooking up the red and black to a 12v adapter and trying the ones which look to me like video to my dvr pc at work and got no image

yellow is a video wire on my home cctv cam, and is also video on S-VHS i think?

any ideas?

The problem, I suppose, is that the colour coding of the wiring could have been made up as the installer went along, you might find no two cameras wired the same way :-)

It might be better to open the camera and see how they are terminated. It will probably be fairly clear on the circuit board which are power and the rails may even be labelled with the voltages. It should also be clear which are signal wires and there is always the chance that some are unused.

I hope I've understood the question correctly but, in short, take a look at where the attach to the circuit board and you will probably get the answer.

the other camera looks to be wired up the same way, i suppose you are right and i am going to have to crack the thing open
