Haloview MC7101 is a very popular wireless backup camera system. This MC7101 is definitely the most cost-effective best seller camera i ever seen. 7" LCD digital wireless monitor with 16:9 aspect ratio,800x480 pixel, Built-in SMART IR-cut, Instant auto pairing, 120 ° wide viewing Angle, and IP69K. Only the factory direct sale can achieve this price.Unfortunately, Haloview's  marketing is not good, and i can't see any its ads.
