    I just installed it and that was fairly simple. Connecting to the wifi was a feat in itself, if you have any other wifi that you normally connect too in range it will drop the dash cam and go back to it. Now once you can get far enough that you can select stay connected it works fine. All channels do show up on the camera screen and you can cycle through them on your phone.

    This camera is awesome and a life saver. In 2023 I got into a car accident that wasn’t my fault which prompted me to buy a cam. Well, fast forward to Nov of 2024 I got into another car accident not my fault! This cam saved me from hassle I probably could’ve ran into.

    Great Dash camera. Has some nice features and picture quality is great. I installed it fairly quick and setup was easy. I did have an issue with 1 camera going black screen after just minutes of use but Best Buy swapped me out with a replacement unit and no issues with this one so far. Would definitely recommend this camera

    Great product and i use it everyday. My only issue was that i couldnt wire it into my fuse box, but its more of a me issue rather than a device failure. I know i would love to have it in the fuse box especially to free up my car plug AND tp use the parking monitor feature. Regardless still a great product that my wife and I use and has come in handy

    -With the recommendation of Best Buy installer, I bought the Rexing-R4. It was installed about a week ago. It has 4 cameras, which gives me from, rear, and both sides of coverage. Now, I will have coverage while driving and/or stopped for the night while we are traveling. Pictures are always better than discerptions when it comes to accidents.

    Nice dash cam

    Very useful dash cam. Four cameras can cover almost every angle including cabin view and especially the side and blind spots, as in my three accidents in last 20 years all were from the passenger side, and would have been missed by the front and rear cameras. Unfortunately I didn’t have the dash cam then. Easily can read number plate if close enough. Four stars because buttons for control are not clearly labeled and can be confusing if not used frequently. Touch screen would have been a great feature.

    The camera is mounted just below the rear view mirror on the inside windshield. There are three cameras on the unit, and one camera in the back window. On the main unit it has your front facing camera and two side cameras. The side cameras look out the front door windows, and also captures the inside cabin. It is a very tiny screen, with tiny writing. Once installed the unit is not easily removed. An odd design feature is how it attaches to the mount… there is a thumb screw on one end and a very tiny nut on the other… very easy to drop out and be lost It comes with a micro sd card… but I bought a 256 gb for the unit You’ll need your manual handy when trying to maneuver the buttons… The app seems like it should work easier… the unit uses built in wi-fi to communicate with your phone (it is a very short range wi-fi- phone needs to be next to the cam) Not a bad purchase and seems to be performing as intended

    I bought this camera and all the 4 channels work very nicely, I drive for Uber and I am satisfied with this camera and I would recommend who are driving Uber , it’s very good specially the rear wide angle and the night vision is really cool and easy to install, and we can see it using rexing app it’s really easy to connect to WiFi. It’s a 5 star from my side.

    The cameras take great pictures and videos. The only draw back to the camera is the fact that I have to reconnect the wifi in the camera to the Pp manually ever time.

    Best 4 channel dash cam

    One of the best 4 channel Dash Cams on the market. It can be installed (hardwired into your car) and it will have the same functions most other dashcams do. The 1080P quality is often better than some 2k cameras, I don't know how that makes sense but it does.

    I bought this knowing the app was trash - and it still is! I tried to give it a go, but gave up early on to save stress. The camera works great as it should, but for one little hitch. IF you forgo the app as I have, you need to rely on the micro card. Well who designed this with the card finger nail knubby facing the mount??? So based on another reviewer I put a loop of cello tape on the card to remove it. Real smart Rexing!!! I also bought a 256 gig card from amazon so I'm happy. It gives me a bit longer than the 64 gig card supplied. In all, all I want it for is insurance protection as alot of accidents, not on camera, are subject to he said/she said. I installed myself. Took a while but very easy and I was being very careful (brand new Telluride) and a few breaks here and there. I installed unit, rear camera and gps but not the parking monitor.

    I purchased this dash cam for all of its features and it was at a devent price. I had it installed by Best Buy and everything is working fine. It was a little diificult to find the serial number after installation. The warranty website says it is on the back of the camera but it is actually on top, under all of the wiring. The unit is working great and will hopefully help with all the crazy drivers.

    Just installed a few days ago but first impressions are good. Solid feel, fit, and finish. Best Buy install went smoothly with a minimal amount of wires showing. Looks like it could be OEM. Camera pictures are clear, if a little small. Still learning functions.

    Great Dash cam that covers all angles of your camera. Hard wiring was too technical / difficult for my car, so just opted for the easier plug and play version. Without hard wiring though, you will miss out on a few features, like parking mode, but you still get a lot
