Review on High-Definition Truck Backup Camera Kit with 7-Inch Monitor, Easy 30-Min DIY Installation for RVs, Trailers, 5th Wheels, Campers - Advanced Rear View Observation System Including Second License Plate Camera - Yakry Y14+ by David Boone

I mounted this camera on the back of our 24ft truck, just under the headlight at the very top of the ramp door. It's about 9 feet off the ground. Installation was easy and I had no trouble getting the cables where I wanted them. However, the wiring itself is cheap and unreliable. If you pull on the connectors, the image on the screen will be cut off, even if the locking rings are securely attached. You should just secure everything in place and then tape the cable or otherwise secure it so it can't move. I got a replacement strap from the seller that was slightly better, but the picture is still shaky due to the 23ft cable that runs from the camera to the strap. I'm not sure I'll try to replace him. When you receive a picture it is nowhere near as clear as what is shown in the listing. This is normal but by no means has the contrast, detail, or color depth shown in the listing, regardless of adjustments you can make to the monitor's display. I haven't tested it overnight yet, so I can't comment on any aspect. The screen must also be mounted so that you can see it straight ahead, otherwise a slight angle can quickly obscure the image on the screen. I've seen some cameras that let you turn them on and off whether you're reversing or driving, but not this system. You need to somehow connect the "Reverse Trigger" wire so that it is always live. However, this would also likely cause the night vision LEDs to stay on all the time and burn out prematurely. Why do you need backup lines when you're ahead? Because the weakest link in this system is the unusually wide camera angle, and reversing lines CAN give you a rough estimate of how close other traffic is behind you. Having used this system a few times I can clearly state that its only real value (at least as a wheeled backup camera) is in detecting whether or not someone is directly behind the camper van. When driving in the left or right lane, the camera image is so wide that when the car is close enough to you to be identified on the monitor, it is almost directly on the campervan's rear bumper. What looks like a coin-sized blob on the screen (is it a car or a truck?) is actually so close it's already fully visible, completely filling your side mirror. You really can't safely use it to determine if it's okay to change lanes or not unless you can't see absolutely nothing on the monitor (or in the mirrors). It might be fine on an open freeway, but once you pull into a town and everyone's driving behind or in someone's blind spot, this camera definitely won't give you peace of mind when changing lanes. 4:3 instead of 16:9 might help, but all of this proves that the 16:9 setting simply stretches the 4:3 image to fill the screen. There is absolutely no difference in the content of the image itself. I was hoping I could zoom in on the image to make it more like real life, but the "zoom" feature only toggles between 4:3 and stretched 4: 3 um. The looks and usefulness of this camera MAY be different if I put it much lower on the RV, but I doubt it. It should be high enough so that the car behind you doesn't take up the entire screen, and you should be able to see what's behind that nearby car. If you just want to know if someone is behind you in your lane, this system will suffice. If you want to rely on it being safe to change lanes, don't do it. The image is too wide-angled to be used for this. I unrolled the tape measure and asked my wife to stand 25 feet behind the RV, then put small strips of white tape on the monitor to line up with the car. will be at this distance. I haven't tested this yet, but it would be the minimum safe distance to change lanes unless traffic is approaching quickly. Had this system had a more natural viewing angle, this "calibration" would not have been necessary. I didn't have to rely so much on the camera image to figure out what I was really looking at, to figure out where the next traffic REALLY was, that using this setting makes driving less safe, not more. You must take this into account. The system must be an accessory and under no circumstances should it replace the rear-view mirrors.
