HELP ANYONE FITTED A REVERSE CAMERA?

[mattyboyc]

Hi all,
I recently got a reverse camera from a forum member and whilst chucking it down with rain today i thought i would hook it up to a monitor i have just to check it's working,so putting 12v to the brass connectors on the back of the camera unit powers up the led light so all good there however when i put power to the camera itself all i get is what can only be described as a very badlt tunned tv,no picture just a mass of squiggles realy,now out of each end of the video cable there is also a red cable, being red i take this as a power lead but giving either end or both ends power makes no difference, what i'm trying to find out is whether it's the monitor thats not compatible or if the camera itself is knackerd,i have also hooked up to a portible tv and got the same results,
Any help greatfuly recieved as always,
Matt

OK mate sorry, I didn't read the guide fully but thought it might offer some words of wisdom on the connection side of things you might have missed.

There are some reversing camera's which feed the RVSL (reverse light on) signal along a red wire the length of the video cable. See post #75 of Reverse Camera link. To test the camera this needs to go to +12v and there should be a ground cable (normally the screened section cable of the power cable) at the camera end - make sure this goes to a good ground point.
There should be a separate cable to feed into the video-in on a monitor -this is normally via a yellow phone connector.

PAL/NTSC check:

Feed the signal into a "modern" monitor which indicates what signal it's receiving - my Pioneer plasma will indicate PAL or NTSC in the top left corner on feeding a composite video source.

Alternatively, if you have a video ipod and video composite lead for it try feeding that signal into your monitor to check your monitor - first set to ipod to PAL output , see what you get, then set ipod to NTSC and see what you get.

Can send it to me and I can check it for you - PM me.

Hi, the picture in post # 75 is the one i have, i have taken the power from a battery charger and had the light working and obviously the camera is doing something as when you take either the power or ground cable off the monitor goes blank and when connected you just get a mess on the screen, anyway pm sent.

..... i have taken the power from a battery charger.......

This is not a good power source as will consist of AC and DC voltages and could be your problem?
Use a constant 12v source - car battery may be a solution.

Hooked up to a clean 12v dc supply and camera works as it should so battery charger was the problem, thanks again Colin.
