The natural split-screen view is less cramped than smaller displays, giving you clearer awareness to spot stones, pets, obstacles and kids when backing up or driving 1-Min DIY Installation: The solar wireless backup camera system requires no drilling or wiring.

With two cameras, one can be placed on the hitch or bumper and the other on a trailer, camper, or horse trailer for flexible coverage
