Review on ZEROXCLUB Wireless Interference Waterproof SW01 by Jonathan Lamp

It's not the best camper cam but for my use on dual carriageways it works great. I asked for an extended antenna and placed it in the middle of the van closer to the truck and it gave decent reception. At speeds over 65, the signal doesn't stay constant, but it's enough to see if someone is approaching from behind. I hooked it up to the top rear center marker light and turned on the light to keep the image constant and it works fine. For the price I think it's done well. I would like a magnetic antenna to place on the roof of my truck and reception will most likely be perfect. Update 3/22/2020: So I just moved the antenna provided to me closer to my truck with little to no visible obstruction between the monitor in the truck and the extended antenna. I now have almost perfect reception both on the freeway and in the city. To be so welcome with this product, ask the seller to provide it and find a suitable place to mount it on your RV. I placed it on the front of my air conditioner, used duct tape and drove about 200 miles on the interstate and it worked great. I hooked it up to my running lights so I have to turn them on automatically but now I can see everything behind me. I have a Ram 2500 with a TT about 25 feet long.
