Review on Nuoenx Wireless Backup Camera Monitor by Eric Jones

This is an excellent camera system with very clear video on an impressive monitor. However, when using the included power adapter, the video stays on all the time. Not bad, but distracts the driver, especially at night. There is no indication what the additional power supply is for. I'm assuming it's meant to be plugged into a backup power source to enable video when backed up. This requires additional information. I would buy this item again.
