4Ucam TWO Digital Wireless Camera + 7" Monitor Quad-view Split screen for Bus, RV, Trailer, Motor Home, 5th Wheels and Trucks Backup or Rear View

Great product, very good distance with wireless.Had an issue when I first powered up as it appears that the cameras are very sensitive to voltage. I had my trailer attached to a separate 12VDC supply, no signal detected from the cameras, could not even get the cameras into pair mode. Contacted 4Ucam, Joe quickly got back to me and suggested that I make sure that cameras were directly connected to the battery where the monitor was attached. His guidance was 100% correct! After connecting the trailer to the truck both cameras synced up perfectly.Monitor mounting option: Shown on a 2013 GMC Sierra DenaliProclip ([...]) No holes in dash!Ram Mounts RAP-B-354U-TRA1 (T-Bolt attachment fits the back of the monitor perfectly) and RAM-B-202U short extension ...Works great ... monitor stays under the dash but does not block anything!

Camera's seem to be a very good quality; heavy duty.Receiver screen good picture, but noticeable lag.First time I plug in an SD card, it works fine. Next time the unit get turned on, it doesn't see the card anymore. And it will not format any card. just sits there saying it's formatting; Hours later it still isn't done. only way to stop it is remove the power. recording was my primary reason for this purchase. Extremely disappointed. Update. Windshield mount failed after only 10 months. Weight of camera is too much for the suction cup to hold.

I don't normally write reviews, but after trying a couple other camera systems to find one that works on my RV, I figured I would write one for this one. I was looking for a wireless setup because it would be too much of a pain to run a cable from the back of the RV to the front. I have a 30' RV and this setup does pretty well.I have both cameras mounted on the back wall up high on the RV. they are powered by the marker lights. One camera looks down at the bumper to give me a close up shot and the other looks almost straight back so that I can see what is behind me. I used this setup on a road trip from Colorado to Florida and back and did not have any issues with it at all. With other cameras I had cut outs or static picture. This one was slightly choppy but only noticeable if you are starting at the monitor. It would probably go away if I was to purchase the extended range antenna.Pros:Great picture even at nightNo disconnects or static in the pictureMultiple camera viewCons: (minor things IMO)It is ~25' from the monitor to the cameras with only 1 cabinet and rear wall in the way and the picture is slightly choppy.The monitor doesn't remember what view you were in when it is turned off and there is no setting to change the default viewAlthough it said it has audio, I never was able to hear anything and was unable to find any volume adjustment on the monitorAutomatic brightness adjustment for day/night would be niceIf the camera is wet from rain or snow, it is hard to see out of it at night (since the IR LEDs are behind the glass too)

Read all the other reviews before you buy. I am ok with the purchase. I have used it one week. I put it on the back of my pick-up to observe the fifth wheel trailer when connecting and disconnecting. For this I plugged it into my 4-wire trailer connector. I put the second camera on the back of my fifth wheel to see when I am backing into my driveway which can be tricky and into camp sites. It works for that. On the road it it does not maintain the picture to see a view of what is behind me. I thought the package it all came in was nice and all parts in order. I might have liked a small Allen-wrench for the screws but I had my own. I don't think the bracket provided to the camera is very good. They could provide something different since you can't swing the bracket to the back of the camera and mount in that way since there is not clearance with the antenna. I am looking for an accessory antenna that will give me a more consistent picture and not cut in and out. I thought it had audio but I have not found that to be the case so far.

The system was easy to install and the product seems to made of good quality. I am happy to monitor the cargo inside my toy hauler as weel as who is behind me before I switch lanes. The parking guides are a plus but just have to get use to how big my trailer is with reference to the lines. Seems to be conserative.I had a question about the product, 4ucam answered my questions immediately and followed up with a phone call, kinda unheard of in today's world.Recommended the system to my friends already.Joe R

These things are supposed to transmit 300 ft. My 5th wheel is only 40 and these cameras are losing their signals constantly also when you mount the camera on the back of the camper the brackets are to short to use with the antenna. So you are only able to secure the camera with 2 of the 6 screws to the brackets. In my oppinion the companys claims of this product are inaccurate. Apparently i can purchase an additonal antenna to make these work 40 ft. There clam of 300 ft no way!

We installed these on our motorhome and they kept turning it n and off and at night one of the cameras was very blurry.We were fortunate when we contacted the company and we were soon told that they were too close together and there might be some interference! That would cause it to turn on and off.But for the blurry camera they sent a replacement right away...unfortunately that one too is blurry but not as much so I was satisfied. Most of the issues seem to be happening when it is cold so we expect to see better results when we head south.....when we first used them for on trip whenIt was nice and warm.Well it is now several months later and we did have more difficulties with the unit but the service we received from the company was nothing short of awesome!They replaced all the cameras that gave us issues without any problems and when the US postal service seems to have lost one shipment they sent us they did not hesitate to send me ano Her one at no charge.Now that I have them properly installed as per their instructions. The cameras work really well and I hit recommend them if you are considering a back up camera... by the way I hooked mine up so they are on all the time my motorhome is running so It’s Like having a rear view mirror for the back of my motorhome.....Thanks 4ucam!!!
