Review on Complete Backup Camera Kit For Large Vehicles: 4 Waterproof Cameras, Night Vision And Parking Lines - BY704A by Lorenzo Wood

Have received excellent support from the manufacturer. Camera and display are as advertised. Have install this on a 26 foot airstream trailer and have used it now for several months. At higher highway speeds, reception gets a bit spotty (image not smooth, jumpy), but seems based upon the exact location and orientation of the receiving display unit. Antenna placement is critical. Overall an excellent unit for the money. Would have received five stars except for the spotty reception. Distance between the two antennas is less than 50 feet.
