My wife and I purchased our first RV this past Autumn and it was immediately apparent I was gonna need something to help me see behind me and better vision on the sides. I have no real interest in putting bigger mirrors on my truck, so a camera system seemed to be the best solution.First off, quality is surprisingly good for both day and night time. I was actually quite surprised at just how good the "night vision" is. We got stuck in a major snow storm at night on our drive back from our Christmas camping trip. These little cameras made it so I could see what was around me and help me make better decisions while driving in blinding snow.Day time quality is very good too, no complaints there. I could read license plates from passing cars and cars behind me without issue.I only have two real complaints. One of which I honestly knew was going to be a small issue, the video delay. The other I'm almost certain is operator error, but still annoyed me. The time between reality of a car coming into camera view and when I see the car come into view on the monitor was a good half second to full second delay. This is ultimately due to the nature of the product. A wireless solution will always have some kind of delay.The second was the recording feature. I could not for the life of me get it to record. Now, I was trying to use a 256gb microSD card in an SD adapter. The SD Card that came with it (64gb!) did record when I tested it on the initial setup. So I'm sure this comes down to a problem with the operator, not the equipment.Installation was a breeze. Hooked up all three cameras to the camper running lights so I could turn them on and off within the cab of my truck. Made some custom waterproof mounts and cable runs for the camper, and easily swiveled the cameras to point in the right direction. One of the cameras had a really weak signal, and after closer inspection saw that the little antenna attached to the camera itself had broken. Customer service was fantastic, though translation at times was a little rough (99% better than most though). They replaced the camera with a new one that was shipped next day delivery. I was impressed.There was no sync process with the initial cameras which was FANTASTIC. Cameras just appeared on screen ready to go when powered up. The replacement camera was incredibly easy to sync with the monitor, took all of 30 seconds.I do wish I had a bit more customization of the monitor. I'd like to be able to move the cameras around to different positions on the monitor, and only display 3 cameras. Instead a 4th square is left blank where a 4th camera goes. Not a big deal as I CAN switch between camera position. 2/3 (left and right camera) and a full screen backup camera view with guide lines. Which... btw... is INCREDIBLY useful when backing up a 32" RV.Excellent product, well worth the price, I've been recommending this thing to anyone and everyone. If I was a bit more confident in my cable skills, I'd probably go with a wired system... but I just don't want to fiddle with cables. The wireless system does quite well. Customer service is also A++++ Actually... probably the best customer service I've ever had with an Amazon retailer. I WILL be doing business with these folks again.To wrap this up, I love this product. Is it for everyone looking for backup support and side views? Nope. The delay will really screw with some people, but for us it's of no importance. I'd also like to add that this product comes with an offer for a free dash cam with a 5 star review. I wanted to make sure this was in here, but I also want to make sure anyone who might read this knows my honest opinion on the product. But... I also need a dashcam, not gonna pass up free.
