Review on Advanced Wireless Backup Camera System for RV & Truck | IP69 Waterproof, Split Screen Monitor & Rearview Reversing Camera | 7'' Wireless Monitor by Steve Campbell

EDIT (05/04/2019): Xroose supports this product very well. I had two cameras in the back of the trailer that weren't transmitting video reliably. They sent me two antenna extensions which after some work on the trailer are now showing the cameras reliably. It took some work to make the brackets for the trailer's roof, but everything works fine now. I have to say that the customer service from this company was top notch. In fact, I don't know if I've ever had the best support for a consumer product like this. For that alone I will seek them out and buy them again if the opportunity ever arises. --- Original Review --- After spending a day (or actually two) installing the cameras and testing each one, I'm happy with all but one. The camera on the back of the trailer (horse trailer), which is the "backup" camera, is not displayed in the 4-person view. However, if I only switch to this camera, the picture appears - at least in my parking space. I have to take it with me on the way. (I've been trying to figure out why this camera isn't showing up) Also the camera blinks sometimes but I've checked the power supply and it's stable (and it's plugged into the same power connector as the internal camera to watch the horses - it seems always working ) I'm wondering if I need an antenna extension for the rear camera as the aluminum frame gets in the way. The rest of the product is good. Mounting options for the monitor are good (although I wish there was another axis of motion so I can tilt it towards the driver without rotating it so it's not level - I have it slightly to the right of center at the top of the windshield assembled.
