The unit does work but there are problems.  The monitor does work but only powers on when the USB cable is pushed in hard.  We think the USB power port for the monitor is damaged and would need repairing.

The camera works but the LED's do not come it.  It looked dead initially but when we connected it to the monitor it worked.  

Please bear these issues when buying this item.  We are selling it as faulty but think the right person can repair it.  Price reduced to reflect the issues.
