What kind of video input is this?

I have a car backseat camera and lcd monitor set that was given to me as a gift awhile back when my son was born. The LCD is about 2sq" with a 12v power input from a cigarette lighter jack. The camera is day/night and is powered and relay's it's video signal through a single 4-pin cable that goes to the color LCD. The jacks on the cable look like a mini phone jack, anyone know what kind of video input type this thing should be using?
My multimeter fried the other day and I haven't gotten a new one yet so I can't probe around and my wife won't let me take it apart...yet.

The cable as I mentioned earlier has 4 wires, red, green, black, and one uninsulated multistrand copper wire.

*EDIT* I've used a led as a test probe on the LCDs camera jack under power from a 9v battery. The green appears to be the main hotwire, it will light up a 3mm LED goin to the red wire, and quickly burn out the same LED to the black wire. The black and red will ark, but cause a short in the power supply. That's all I've got so far.

I have been abe to run the whole set off of a single 9v battery so it's power drain isn't too great. Would like to know if I could use the monitor for other video sources and/or input the camera to a different monitor.

heres my input but don't shoot the messenger if i'm not correct, but here we go. coper is the main ground red positive power feed green video and black is the ground for video. so my taking it be a composite video in.

I had a suspicion last night that it might be composite. I'll try it out and see what happens, but I've got to make some adapters that I can probe it with first without harming the set.

Well I'm reviving this because the wife finally tried to throw it out so I figured it's open season for me to hack it apart! Was using it as it was intended before so I couldn't.

as I suspected it is composite. Yellow was signal, blk ground,red power, and copper was another ground that I diddn't use. I'm able to power the camera by itsself with a 12v AA battery pack, solder in a composite vid cable and hook it up to my TV and it's night vision still works. So it's a self contained camera that's about the same size as a webcam. The 2.3" screen works the same too. Now I'm trying to come up with projects for it! One idea is getting a wireless A/V transmitter and receiver and putting it in an RC.
