I have been using this on my RV totorhome and trailer now for a bit. I love it! It provides incredible visibility for the sides and the rear. I decided not to use the 4th camera on the front but mounted on a magnet that I used in front of my gooseneck ball to help hitch up the trailer making it so easy. Then when I have the trailer connected I use an extension and mount this camera on the rear of the trailer so I can see behind me when traveling (the primary rear view camera is blocked by the trailer when I have the two connected). The size of the screen is very nice as it still provides nice views with all 4 cameras going at the same time. This entire setup works very well and provides awesome functionality and increased safety.

Why did you pick this product vs others?:Best fit for my needs.  The 18 pin cable was a bit short for my needs, I emailed and asked if I could purchase an extension.  They shipped me a 16 ft extension cable absolutely FREE.  Customer service is great fast responses and fast action received the cable 2 days later couldn't be happier.  Not installed yet but bench test went perfectly.  

I've just begun installing my new DVKNM 4K RV 360° camera system. The parts appear to be well engineered with "metal, not plastic" housing over all four cameras, impressive. There also appears to be plenty of cable to get from the camers to the electrical hook-up area. The instructions are well written and supported with an email address. My first question was answered in less than 12 hours.Listen, if a 76 y/o fart like me (with 1/2 a brain), can do this, well, you too can do this installation.Remember, "Technical support" is only a message away. Now, go make yourself safer and get those cameras installed.

Gave it a quick test and was pleasantly surprised to see how well it works. Good resolution even at night mode. The system is heavy duty, cameras are pretty sturdy, and monitor is good size. For my setup, I did need an extension cord for the car charger cable and the 18 pin monitor cable which they let me know promptly ( in same day ) how to get. Thanks Carey!

This device performs really well! Routing the cables can be a bit of a hassle, but once it’s set up, you’ll be glad you did it. The screen has a clear, crisp image, and setting it up is straightforward. The mounting bracket is solid, and the back of the screen is designed to be flexible for mounting on a flat surface like a dashboard — that’s where I plan to install mine when I get the chance.”

Very disappointed with this system (DVKNM TP104). After I spent many hours installing the monitor and cameras, 1 camera changed to infrared only as I was pulling my van into the garage. I tried to use the system today, but the camera still shows no color. I tried to contact DVKNM using Amazon and the DVKNM email address, but my email was rejected. The second, and most important issue is, polarized sunglasses will block the monitor 100 %. I can only see a black screen when I am wearing my polarized lenses, which I wear 360 days a year. For me, this system is totally worthless.

Todo el equipo fue instalado sin mucha dificultad y las imágenes son increíbles solo que considero que lo más importante es extraer un video para el móvil o algún dispositivo para guardarlo como prueba o evidencia, instale en mi movil la aplicación TCLink según el manual pero solo me permite compartir la pantalla de mi movil con el equipo no a través de un cable usb qué compre adicional ojo solo usb que permite compartir datos y la opción bluetooth solo permite recibir llamadas y reproducir música. Talves tenga esa opción de extraer videos que considero sea lo más importante, pero no la he encontrado.

This is a pretty nice device to have for a rv trailers, big truck, or van. It would be a bit of an overkill for a car if you happen to want to use it for that. The cables that it comes with is rather long so you get plenty of length to work with when running this through your rv trailer. The screen on this device is HUGE. It actually is 10 inches (rounded down) and it gives you plenty of space to work with. You can utilize all the four cameras so you can see record and see all sides of your RV. It works well in daylight or night time which is great. It is fairly easy to put into your dash without much issue. The main cable is integrated into the device so if you happen to break that it is extremely difficult to replace. Regardless, the cable itself is pretty thick and durable so I do not see that being an issue. You do have to screw these devices in so be aware of that. It requires a bit of drilling which can be what some people do not want to do. It is not something held in by suction or such. Again this product does come with all the wiring you will need to hook this device up. All the wires are decent length and very durable which makes the box super heavy. None of the cameras are wireless so it does require you to run the lines through the RV. The cameras themselves are fairly easy to install on all sides. Again you will need to drill in order to mount them. I had a chance to test it in rain weather and the camera can be blocked from the water hitting it and drips down. This happens to any camera not just this one so be aware of that. The front camera is actually really nice to have to ensure you have record in case something was to happen. The screen control is fairly straight forward to use and the device does have motion detection to ensure you are not wasting too much memory. I have tested the sensor and it actually works pretty well. When there is nothing in motion within proximity no recording happens in order to save memory space which is great. Now I have never ran into anything so I am unsure if it will actually continue to record on collision nor would I ever want to be in a collision. It does however keep a pretty good recording. The screen is touch screen and it is easy to navigate the controls on the screen. It also can be connected via bluetooth to your phone for playing music and such. Be aware that you will need to hook this up to your audio system in order to play music through the speakers. It comes pre installed with 128 gb card. It was actually inside the screen already when I opened it so be aware of that when you get this. I am unsure of what the max memory this device can take. It records in a loop so it'll override any old footage. Overall this is a great product for big trucks, home vans, and RV trailers. It does require you to drill into your RV and such in order to place the cameras inside so be aware of that when you get this and plan accordingly. The wires are very durable and gives you plenty of length. The picture quality is amazing and works in day or night. The only problem I have is that the screen cable is integrated so it becomes harder to replace if it burns out.
