Rear View Camera Kit.
This is an Ebay bought camera kit £49 for the screen and one camera, another camera at £16, Two extra lengths of AV wire and two connectors another £15, total around £80 'ish.
I tried wireless but it suffered from interferance and loss of picture.
I have both camera's on whilst driving, using the rear view camera on the caravan mostly.
The car camera is attached by using neodymium magnets taped to the camera body and then placed on the rear tailgate. This is brilliant for hitching, it has only let me down in brilliant direct sunshine, and that was once, even in near total darkness the night vision works well. I leave the car camera attached whilst driving and now and again have a look at whats happening at the hitch.
The caravan camera is atttached using no-nails direct to camera body. You do have to angle it down slightly.
If all else its a great gadget.

Try and look past my reflection, the images ar every sharp, but my caravan camera has a habit of changing greens to purple, it was a super cheap camera, and it doesn't detract from the usability.
For £80 I'm dead chuffed!
