Review on Haloview MC7108: Wireless RV Backup Camera System with 7'' Monitor, Built-in DVR, Infrared Night Vision, Wide Viewing Angle - Ideal for Trucks, Trailers, RVs, Pickups, Camping Cars, Vans, and Farms by Meech Elliott

I have the rear and side cameras and am very happy with them. Image clarity is incredible and installation was pretty easy. Plan on using the old gasket if your trailer is pre-wired and purchase an adapter kit. Plan to use silicone gaskets to seal it. I cut the old gasket to fit the adapter bracket. If you have trouble connecting your camera, check the polarity (they are polarity sensitive). The cameras are of high quality, work perfectly in day and night mode and have a wide viewing angle. I now have 3 cameras and can get a 4th so the truck can see the hitch when hitching a trailer. I've already recommended them to a few friends. ***Update: I'm having trouble restarting the monitor every three minutes. I sent a message to support and was very happy with the result. A few days later I received a new replacement monitor, a few days later I installed it in my truck and synced it to the cameras. Not only is the product great, the support is fantastic.
