Customer Ratings & Reviews

I decided to invest in the Rexing R4-RD Dash Cam after a really frustrating experience. A few months ago, I parked my car at a shopping center, and when I came back, there were scratches and a small dent on the side. No note. No witnesses. Nothing I could take to the police or my insurance company. It was basically my word against no one — and that’s the worst feeling. That’s exactly why I chose this model. The built-in 360° motion parking monitor was the biggest selling point for me. Now when I park, I actually feel at ease. The camera automatically records if there’s motion or impact while the car is off. I don’t need extra add-ons or complicated wiring — it’s already built in. Knowing that it’s watching all sides of my vehicle 24/7 gives me real peace of mind. The 4-channel setup is another reason I’m happy with this purchase. It records front, rear, and both sides — not just the usual two angles. Most accidents and parking lot damage happen on the sides, so having that coverage makes a huge difference. I also like that the side cameras can rotate inward if I ever want cabin monitoring. The infrared lights work surprisingly well at night, keeping the footage clear even in low-light conditions. Video quality is solid across the board with 1080p HD recording on every camera. The Wi-Fi and app support make it really convenient. I can connect through the app on my iPhone and review footage without removing the SD card. The built-in GPS is another feature I appreciate — it tracks speed, route, and location, which could be very helpful if there’s ever a dispute. Overall, this dash cam changed how I feel about leaving my car parked anywhere. Before, I would worry and constantly check for damage when I came back. Now I know if something happens, I’ll have proof. For me, that alone makes the R4-RD completely worth it.

I've been using the Rexing R4-RD for a month now, and honestly, the peace of mind is worth it. Having 4 channel 1080p recording is a game changer for me because it literally covers every side of the car. The best part is that the cameras are easily adjustable, so you can actually pivot them to get the exact angle you want, whether you're to catch side door dings or just want a better view of the cabin. The installation was easier than expected because of the OBD hardwire kit. You just plug it right into the OBD port and you're good to go. It's a smart move because it has built in protection to make sure it doesn't drain your car battery, so you don't have to worry about coming back to a dead car in the morning. For the parking monitor, it's super responsive. Once it gets triggered by motion or an impact, it captures about 5 minutes of footage, which is plenty of time to see exactly what went down while you were away. As far as the actual video goes, it's solid. Whether it's bright daylight or late at night, the quality is clear and consistent. It's definitely enough to see exactly what is happening all around the vehicle at all times. if you want full coverage without a massive headache, this is a great pick.

The Rexing R4-RD is filled with new features and options to make it a great Dashcam. It starts with a 4 camera system and radar activated parking lot monitoring that attaches with an easily movable suction cup system that holds the device in place in any weather and road conditions. It also incorporates a separate plug in GPS unit. The GPS unit allows you to play videos with their downloadable software and see where the vehicle was on Google maps in addition to the vehicle speed and camera video. I also liked the simpler ODB port power cable that you can plug in and allows you to set the voltage that it will cut off so you don’t drain your battery too low. With a cable that is easy to disconnect at the camera and the main unit end it simplifies installation of the rear camera. A quick note, unlike most Rexing Dashcams this one did not include an SD card which must be installed to record your files. While the main unit looks big it tucked nicely behind my rear view mirror without blocking any of my view. This is my new recommended GPS system.

I'm replacing an older dash cam and so far, the product is working great. My old dash cam was wired directly to the fuse box using both mini-USB connectors to the front and rear cameras. So, it was a little challenge to remove all the old cables that was nicely tucked inside the front driver pillar and roof panel. I ran the new smart hardwire kit and the rear camera cables in place of the old cables. WOW, I couldn't be happier with everything hidden and out of sight. Finally, I was able to mount the suction cup and started to connect everything into the dash cam including the GPS module. I've been using it for a week now and I have to hand it to Rexing for a quality-built dash cam. My biggest thing with this unit is that now I actually have a security camera for my car when I'm away from it. That feature alone is worth my upgrading to this unit. The overall of the video quality was good and was ok when reviewing it on a bigger computer screen.

I recently installed the Rexing - R4-RD Dash Cam All-Around 1080p, Built-in 360° Motion Parking Monitor, GPS, App Control for Windows, MAC OS and iPhone – Black, and I am blown away by the quality. The 4K front camera provides incredibly sharp footage—I can easily read license plates, even at night or in the rain, thanks to the high 1080p resolution sensor. Installation was surprisingly straightforward, and the app interface is intuitive for downloading clips directly to my phone. The parking mode (paired with a hardwire kit) gives me total peace of mind when parked. I highly recommend this for anyone looking for the best protection on the road.

Dashcam is all updated and fresh! Improved from the last one I owned which was the V2 Pro. Unfortunately with updating, the old hardwire cable does not work, and the rear camera cable does not work with this unit. So yes, I have to rewire EVERYTHING. Works nicely so far. Great addition was the camera pointing straight infront then 2 cameras for seeing the sides! But, Rexing, why not just finally put a 360° camera on the bottom and get a full view?!?!?!? Forgot to mention the best part!! It comes with the hardwire cable finally!!! And it goes straight to the OBD II plug so no guessing what fuse to select and hope its good for parking. Maybe rexing can upgrade the usb c cable tho, why do yall have it on a 90° angle? If it goes on the window and the obd is on the driver side, why does the cable angle to the passenger side? The cable gets ran straight up to the headliner, so cable will kink and could become damaged eventually. Overall, I like this dashcam so far.

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.

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!

Been running this dashcam for a bit now, and I’ll tell ya what, this thing just works the way you want it to. Setup was straightforward, video quality is clean all around, and having that full coverage gives some real peace of mind when you’re out on the road. What I especially like is that the motion sensor is built in this time. With my previous model, I had to go out of my way and buy that separately, which was a hassle. Here, it’s already taken care of, no extra steps, no extra cost. Also a big fan of the OBDII power connection. It’s a much cleaner setup, no messing with fuse boxes or running wires all over the place. Plug it in and you’re good to go. Nice bonus that the kit comes with a rear camera and GPS. I’ll definitely be using the GPS, but as for the rear camera even though the quality looks solid, I’m probably not going to bother installing it. Overall, solid piece of gear. Reliable, simple, and does exactly what it’s supposed to without any fuss. At this point, every car in my family is running a Rexing dash cam, can’t complain, just not sure what I’m supposed to do with the older ones now.

Another great product from Rexing! Easy to install with valuable features like being able to connect power thru the OBD port for extended functions, GPS module included, and 360 coverage. Because it's continually monitoring the battery and will shutdown if voltage goes too low, it is able to record while parked without fear of not being able to start the car. This my 5th Rexing Dashcam because they keep getting better!!!

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.

Honestly, I’ve been really happy with this dashcam. The video quality is clear enough to actually make out details, which is all you really want from a dash cam. What I like most is the 360° parking monitor. it’s nice knowing the car is being watched even when I’m not around. The GPS feature is a solid bonus, and the app was easier to use than I expected. Setup didn’t take long either. Overall, it just works the way you’d hope, no hassle. Definitely worth it.

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.

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.

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

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

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!!!

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.
