I wanted a camera system that I could put in my horse trailer so that I could watch my horses on our 2,400 mile move cross country. This did it's job beautifully. The monitor is big enough that if you want to watch split screen, you can and still be able to tell what's going on. One of the cameras we had mounted inside the rear of the horse trailer, facing the front of the trailer, so that I could see all four horses. The second camera we had mounted outside the back of the trailer to act as a back-up camera. During the four day drive, I mostly kept the monitor on just the horses. I never lost signal nor was the picture ever blurry or compromised. We had the system installed by professional and he hardwired it into the light system on the truck so that all you had to do to turn the monitor on was to turn the running lights or headlights on. It was brilliant. I would recommend this system to anyone looking for a similar set-up.So easy to install and use. We mounted this camera on the back of our camper and it is absolutely perfect! Gives us comfort as we drive down the highway to see if we can change lanes or not. It also has a microphone on it so as one person stands behind the camper they can easily talk to the driver. I would highly recommend this camera!Screen is nice and big, we are using this as a back up camera on a CAT D6N LGP for fighting fires in Northern California. One camera points to our winch on the back of the CAT, the other points further back to see when backing. Nice set up! We wired this in to a switch to have the ability to turn off when not needed.I had a problem with one of the cameras getting water inside after a rain (blurred the image). I was able to remove the camera from the case and cleaned the lens, and case. I resealed the O ring with silicon and sealed the antenna connection with silicon. Expect rain this week so it should get a good test. The seller has offered to send me a new camera which I what I tried to get the Amazon rep to do. Amazon wanted me to uninstall and send everything back. This is a very reputable seller!!!Installed on a J and M grain cart works goodThe picture quality is wonderful. Easy installation. I like it so much that I’m buying another camera. I had a small bushing missing and it was sent immediately. Susan is a great person to work with, she is kind and does what she says immediately. Susan is extremely helpful. Would I use Zeroxclub again, absolutely.I installed on my tractor and the view from the front and back is what I was looking for. Very easy to install and hook up. For the price it is well worth it.Tuve un pequeño problema con el equipo, me puse en contacto con servicio al cliente y todo quedó resuelto bien rápido, me enviaron una nueva unidad de reemplazo. GraciasI wish I could give this 0 stars.Installed 2 cameras inside our horse trailer to keep an eye on the horses. Everything was easy to install. Paired up with the monitor no problem initially. Closed the trailer doors and instantly lost signal. Very disheartening, as the sole purpose of purchasing this model was the promise of long range and no interference. Hoping there is a remedy to this issue, as I'm sure I'm not the first to experience it.Update - spoke with the sales representative and was told I needed a range extender antenna, and that one would be shipped free of charge. Going on 2 weeks now, with no communication regarding shipping of any sort, and a unit that still does not function as advertised. Extremely frustrating and poor customer service.Update 2 - received the antenna extender 2 weeks later, and it did not work. Opened case on back of monitor to see if something was broken inside, to find that the antenna wire was broken from the mother board and the cheap solder job did not hold. The part where the antenna connection mounts to the back of the case is not secure to the case in any way, and just has a thread on nut to snug it to the plastic on the outside. When you tighten the antenna on it spins, because it is not secured... just absolute garbage construction. Also upon closer inspection, one of the antenna wires is broken from the connection point... These are not inexpensive units and for the cost the construction of this product is absolutely garbage. 2 months later I'm stuck with an expensive paper weight. Pissed off is an understatement.I have 3 cameras and non of them are waterproof
