Need Help for security camera details???

I have just sold my security cameras to a friend and whilst they all worked when taken down we cant find one of the leads that we need, does anyone on here have anything to do with cameras, we need to know how to wire this one up as it has 6 wired not the normal two ie paower and coax, the wire colours are red/white, red, black, black/white, yellow, white, we dont have a make on the camera but we do have GTNV40VF/S written on the manufacturers label and it is an infra red camera. we need to know which wire goes to where so that we can loop it in the system.
thanks in anticipation
