9" Wireless Backup Camera System for RV Truck Trailer Camper, 9 Inch DVR Quad Split Monitor IP69 Waterproof HD 1080P Wireless Rear Side View Cameras, Stable Signal Observation System - B904

This camera system is fantastic! I installed this system on our 38' (hitch to bumper) gooseneck aluminum horse trailer. I purchased a 4th camera separately so I could place a camera on each side of the trailer, one off the back, and one inside looking at the horses. Installation was easy and the signal strength from the cameras to the monitor was great! We recently used these on a 2300 mile round trip and they worked great. We had two or 3 times the entire trip where briefly the monitor screen went dark and back on again in a flash. The monitor was easy to view in the daylight but was a little too bright at night but, I think there is a dimmer setting I could have found. I didn't like the monitor mount for my application so I purchased separately a suction cup dash mount for a tablet and it worked great. The camera resolution met my expectations in daylight and at night. For this price point I highly recommend this camera system!

This is the third Zeroxclub camera system I have purchased. The first two are still in use on RVs thatI sold. All 3 are high quality in terms of picture resolution and longevity. Customer service was outstanding. They were easy to install.

Approx 3 years ago I ordered my first ZeroXClub wireless camera with 3 cameras for my travel trailer. Installing cameras was pretty basic, connect power to light circuit off travel trailer and then connect ground. Only issue I had was trying to add another camera. When I connected second one, it replaced the first camera. Customer service is amazing. At first I was annoyed because you had to email them for help. I wanted to talk to someone. However, I sent the email and I swear in less then 30 min I had a reply and guidance on how to add 2nd and 3rd cameras. Picture quality was awesome, everything worked perfectly. After couple years of use I had an issue with the power plug. I sent an email explaining the problem and within 2 days I had a replacement power cord. Now I've sold that travel trailer and moved up to a 5th wheel. I needed another wireless camera - I instantly ordered from ZeroXClub, my new camera system with 4 cameras this time. Just received it, installation was again very basic and everything is operating perfectly. I strongly recommend Zeroxclub merchandise, the quality is high, picture is amazing both day and night at and their customer service is incredible.

Although product works and installs easy. After driving during the day for one week, Monitor is not bright during daylight hours to view clearly. Moving monitor to a different location might help but not in a good location. Adjusting screen brightness to the max didn't help. A brighter screen would make it better.

There's plenty of positives and little negative. This product works as described.Pros:-Sharp video-Simple Installation-Screen can be permanently or temporarily mounted-Long lengths of wiring included, cut as needed.-4 cameras and all 4 can be viewed at the same time, or individually for bigger picture-Good wireless range(one of 4 cameras is on back of 30ft bumper pull trailer behind a 25ft long truck)-Price: less than half the cost of major name brand camera system.-sideview cameras provide great viewing angleCons:-Cameras are not wide angle. This means no fish eye distortion, but it also means if you want to see the back edge of trailer and any reasonable view behind you it will take both of the square cameras. One pointed down, and one pointed back.

*** UPDATE*** The seller saw my one-year review where I mentioned that one of the side cameras quit working after 11 months, they reached out to me to verify my address and sent me a replacement for free, and even followed up several times to make sure I was happy. I am happy!After one Year:CONS:- Monitor menus could be easier to navigate.****FIXED*** See the update above. Driver side camera, not working, it lasted about 11 months. died suddenly. Has power, tried to repair it. Maybe moisture got to it?PROS:- Customer Service- Rear camera working- Clear image day and night- Love the 10" monitor- Doesn't lose signalI really liked this camera and bought the 10" monitor. Just got back from a 6-month trip, these cameras were very helpful and improved our safety on the trip. I would suggest applying some sealer to any area on the cameras where moisture could get in.

Finally got the 3rd side camera to work, system is up and running. The pros: easy installation and very responsive customer service. Picture quality is good. Price is ok given the so-so quality of camera and plastic monitor. Not sure how long this system will last. The cons: took replacement of 3 different side cameras to finally connect with monitor. First one only showed half picture, the other half was black. The 2nd camera only worked when at a standstill then picture freeze. So they sent us an extended antenna which did nothing. 3rd camera finally worked as it should. Just took me 3-months to find time to bring home 27 foot trailer from storage and plan the next trip out glamping. By this time I am obviously committed to this system. The monitor is made of cheap plastic case and sits on the dash, I am concerned it will not weather the sun. Like others have mentioned, buttons feel cheap and limited to changing which camera you want to see first, if you didn’t pair it in the order that you install them. You could pair them again but after all this effort to get them to work, I am going to leave it as is for now. Split screen choices is also preprogrammed and cannot be customized. 10” monitor was my choice and made it much easier to see back there, but way too big for the dash, I would have done a 7” now that I know. I don’t have another brand to compare this one against to say it’s any better but definitely not I would rate as 5-star.
