Customer Ratings & Reviews

I've been using this product for two weeks now and it's been working like a champ. My favorite things about this camera is the radar motion sensing. The sensing is reliable and seems to work every single time. My old dashcam which used the camera to sense motion didn't always catch motion around my car. The other thing I like about this product is the multiple cameras. The cameras cover the exterior and interior well. Once nice feature I found that this one had was the ability to flip the rear camera if needed. This was helpful to me because the way I had to install the rear camera, it had to be mounted in reverse so I took advantage of the flip function. I would definently recommend this dashcam to others. Great video quality and great features!

Let's first get started with the specs. All FOUR cameras are 1080p and result in very good videos with clear images. It charges with a USB-C type connection, and includes an OBD attachment (more on that later) for full integration of the parking monitor, motion detection and all of that. The outside cameras pan AND tilt to help you get the best angle for capturing a nearly 360-degree view around your car and inside (if desired). The suction cup is very strong, but you really need to follow the instructions and prep the glass prior and it must go on a uniform surface (don't place any part of it on the little black dots on the edges of the windshields. The UI is very easy to use with a M-button for Menu and toggles to make your selections. I placed the GPS logger near my camera as it was already within the sky's view, but the GPS logger does come with a longer cord if you need to place it some place further away from your camera. Now, let's get to the install. By far, the easiest install ever with the OBD connector, with one caveat. Please note that the OBD connector is adjustable. If you find that your camera is not turning off when you shut off your car, adjust the voltage on the module from the standard 12V to something higher (I chose 12.4 and it works for me). What this OBD connector does is provide a constant source of power (for parking and motion, when activated) but also doesn't keep the camera ON unless the car is running. When your car is running the Voltage in the system is often above 13V and that triggers the camera to come on. When you turn OFF your car, the Voltage drops, but varies by car. 12.4 worked for me and this means when the voltage is less than 12.4V, the camera shuts off because it knows the camera is off. This camera will take up to a 256GB Class10 microSD and you will get 4 clips per segment of recorded (one for each channel/camera. As the card fills up, it simply overwrites the oldest videos and keeps on going. This is a large camera (obviously, with the 4 channels) so try to find the safest place where it doesn't interfere with your view or your car's safety cameras (if applicable). The results are wonderful, the installation was a snap, the coverage is unbeatable, and the features (e.g. IR Motion Detection) are top notch. I love this camera and its features. Rexing has been my brand of choice for dashcams and their customer service has been wonderful for me as well. Love it.

My girlfriend needed a 360° dashcam for her car due to the driving habits and careless/distracted driving of people in Texas. Since I owned an older version of the R4 (before Rexing released the R4-RD), she said she wanted to try a 360° dashcam herself. After using her R4-RD for a week, she has said she is extremely happy with it. Not only does it capture all the views around her car in both day time and night time conditions since it has IR functionality, it has an added module for GPS speed logging and a radar functionality for passive monitoring while parked. As for interface and use, the buttons and interface are very self explanatory. It is easy to swap between each view for a larger view (the default view is all 4 views on one screen, one per quadrant). This specific version of the R4 does have additional functionality over my older R4 (the GPS and monitoring while parked) but as a result, the initial setup has a slight departure from the center console ports for power. This camera uses the OBD2 port located by the driver side, usually by the gas / engine hood levers (the same port used by mechanics when they hook up to your vehicle). This is what allows the camera to operate while the car is off and it appears to have a fail safe that shuts the camera off if the car battery depletes to a certain level, allowing the car battery to recharge on the next drive. It is important to keep in mind that if someone wishes to utilize the full functionality of the camera, such as the rear view or the GPS speed monitoring, it requires a total of 3 wires to be run from the main camera: the wire for the camera placed on the rear window of the car, the OBD2 wire for power, and the wire for the GPS speed logger. This can all be accomplished very easily but some proper care and taking the time to run the wires appropriately will make the finished product look much better, as this should be a "set it up once and leave it alone for the long run" type set up. In future iterations, it would be great if the GPS speed logger could be integrated into the main unit, as that is one less wire to run from the main dashcam and one less thing to place in the car.

Over the years I've had the Rexing V1LG (1080p, 720p), Rexing V1P Pro (1080p, 1080p), Viofo A229 Plus (1440p, 1440p), and now the Rexing R4-RD (1080p, 1080p, 1080p, 1080p). I really enjoyed the V1LG long ago as it performed well and was able to handle the intense heat in Arizona. Of the Rexings I've had they've all held up well to the heat. The R4-RD is a different form factor than the Rexings and the Viofo units and I am not sure I am going to like it. Here in Arizona we put sun shades up and with this hanging down instead of wedged on the windshield this is going to get in the way. And with the suction cup being plastic and sitting in the sun I truly worry about the longevity of the unit here in Arizona. What I do like is that the R4 comes with a OBD2 power instead of a cigarette lighter power - finally we arent forced to get a hardwire kit. Overall, the Viofo has better optics, but less cameras. It is kind of a novel idea to have other cameras aimed more at your flanks than just straight ahead. But at end of day I think this unit will go to my wife's car as she is more likely to have the kids and the cameras may be better suited for that vehicle than the Viofo in my car. I value the slightly better image over the novelty of so many cameras and like the wedge form factor more.

The Rexing R4-RD is an excellent buy. I needed to buy a Dash Cam for my new 2025 vehicle and am very happy I made the purchase. Excellent quality video and it looks good. It only took Best Buy 30 minutes to install it which also made me happy.

This is the first camera i have bought where there are multiple angles being recorded. This comes in handy especially with children and safety. The amount of relief this cam brings knowing that i have all my bases covered is unmeasurable. I have always been a safe driver however the people on the road are the ones you truly have no control of. Easy to instal, the resolution is unmatched, the instal videos and warrenty are helpful and reassuring. I could jot ask for a better multi cam.

This is my 3rd Rexing dashcam and it is absolute wonderful, clarity of video and built-in parking which I missed earlier ones are great addition.

I love this Dash Cam. It looks great in my car and it gives me peace of mind having it. I like that it has multiple cameras to capture video from different angles. It's easy to access the captured video using the Rexing Connect App which works on my Android phone and my wife's Iphone. The video is high quality and very clear. I am very happy with my purchase and I would buy it again.

This has better button position than existing 4ch rexing dash cam I had before, mounting suction cup is holding well. it will be better to include how to adjust smart hardware kit to understand how it operates for the voltage cutoff

Installed on my Tundra truck Love how I can record front, both sides of car (blind spots) and the back with the rear camera that I installed on the rear windshield Has a GPS and motion detection too!!!

Feeling good with added security of the dash cam now I'm all set

Got it up and running. Super excited about the coverage capability of this one!! Already catching some wild and crazy moments, as I spend a lot of time on the road.

Good camera but not easy to use in the beginning. Overall a good camera

Best Buy did a very good job installing my rexing dashcam

I made sure that I bought the kit to go with it got it installed through Best Buy and I've had to come up here multiple times because my battery was dying I have a 2024 Toyota and my battery was doing great but I had them unhook it for a little bit and my battery just never went back to life so after two days I've been unhooked I just went ahead and bought another battery and now I just had them connected back so we'll see

I can honestly say the Rexing R4-RD 4-Channel Dash Cam has completely changed how safe I feel on the road. It offers true 4-channel coverage, recording everything in front, behind, and to the sides of my car in crisp 1080p HD. The adjustable side cameras are a brilliant touch, letting me capture the cabin or blind spots perfectly. ​What really gives me peace of mind is the built-in 360° motion parking monitor. It provides reliable 24/7 surveillance without making me buy extra accessories, instantly saving footage if it detects an impact. Plus, the infrared night vision is stellar, keeping video incredibly clear even on pitch-black roads. ​Managing everything is a breeze, too. The built-in Wi-Fi connects instantly to my phone, while the GPS logs my speed and routes seamlessly. Backed by smart collision detection, continuous loop recording, and a reliable supercapacitor, it is an absolute lifesaver. If you want total peace of mind while driving, I cannot recommend this enough.

I have always liked how Tesla's can record 24/7, but with the Rexing R4-RD any car can have this feature. The R4-RD is not only a wonderful dash cam but it also has added protection whenever the car is parked. I drive a 2018 Honda CR-V Touring and for me personally I commute and park in an unsafe part of my city so having this gives me a peace of mind. If the unfortunate should happen I have evidence. The camera box includes everything you need for a fast and easy install. Its nice Rexing keeps this in mind with every product and even generously includes a micro SD card. The camera is also powered via the ODB port so installing it is easier compared to other dash cams. The inclusion of a suction cup mount not only made the install easier but adjustments were also easy since other dash cams usually require adhesive or double sided sticky tape to install and are difficult to move once they are stuck in place. Overall I highly recommend the Rexing R4-RD Dash Cam since its a very solid choice and you can consider it your "personal sentry" for your vehicle!

I’ve been using the Rexing R4-RD for a few weeks now and overall I’m pretty satisfied with it. The biggest reason I chose this one was the full 360-degree coverage with four cameras. It records front, rear, and both sides, which gives a lot more confidence compared to basic single-camera setups. Installation took some time because of the extra cameras and wiring, but once it was set up, it worked reliably. Video quality is clear enough to read plates during the day, and night recording has been decent so far. I also like having GPS built in so speed and location are saved with the footage. The parking monitor feature is another plus, especially when the vehicle is left outside. The Wi-Fi app works well for reviewing clips without removing the card, although it can take a minute to transfer larger files. Overall, if you want full coverage around your vehicle instead of just front and rear, this is a solid option. It’s not the simplest system to install, but once it’s in place, it gives good peace of mind.

This is my third Rexing product, and honestly, this one might be my favorite. The R4‑RD really does give you coverage from every angle, so I can see what’s happening in front, behind, and around the car without any blind spots. The 360° motion parking monitor has already caught a few people walking very close to my car, which makes me feel a lot better about leaving it in parking lots or on the street. The video quality is clear and detailed, day and night, and the built‑in GPS is a nice bonus because the speed and location are saved with the clips. The app is actually pretty convenient—I can quickly pull up videos on my phone or computer instead of messing with the memory card every time. Installing it does take some patience, since there are multiple cameras and cables to route, but once it’s in, you really don’t have to mess with it much. Overall, it feels solid, reliable, and exactly what I was hoping for in an all‑around dash cam.

I’ve been really impressed with the Rexing R4-RD—it provides true 360° coverage with four cameras, so I always feel like my car is fully protected. The 1080p video is clear day and night, and the infrared lights help a lot in low-light situations. I also love the built-in parking monitor, which automatically records any motion or impact while parked. The Wi-Fi and GPS features make it easy to review footage and track trips right from the app. With smart collision detection, loop recording, and a 64GB card included, it’s a complete and reliable setup right out of the box.
