Review on 📷 Haloview MC5111 5-inch 720P HD Digital Wireless Backup Camera System with 5-inch LCD Rear View Monitor, IP69K Waterproof, Reversing Built-in DVR Kit for Trucks, Trailers, Buses, RVs, Pickups, Campers, and Vans by Dylan Goins

I've tried pretty much everything to get this to work. The camera package should include a power cord for the setup process. Walking back and forth from the truck to the back of the RV is a pain and STILL doesn't work. I will try 1 more thing but after that. Did! Update: It's set up and running with a 12v portable battery. Did over 250 miles yesterday and the camera worked a bit. It has very poor lag, and if there are a lot of power cords, it cuts out for a minute or two. During the drive, I see a truck approaching my van, but it's actually already standing on its side. I do not recommend buying this camera, or if you do, take what you see with about a pound of salt by TRIPLE checking your side mirrors!
