Excellent picture quality for something so small, we use it connected to our front door camera. Has 3 connectors dangling from a single jack plug, 1 for 12v 1a input for power, 1 composite video input and 1 audio.
Although I have given this very cool monitor 5 stars, there are a couple of negatives which don't really relate to the monitor's performance or quality.
1) The input jack is on the left hand side of the case which seriously spoils the way it looks, especially if you want to mount it on the dashboard of a car. A right-angle plug into the back would have been MUCH neater, I can see why it is done the way it is, but it could still be better.
2) The supplied power supply is AWFUL! I've had two of these now and BOTH power supplies have failed so i'm fairly certain you will need a better quality replacement at some point. don't assume the monitor or input is faulty as I did...
