Customer Ratings & Reviews

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.

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'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.

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 already have Rexing dash cams on both vehicles here, and as I was starting to look for a new one for a new lease this one came handy. I'm using it for a month now, and comparing its images with the old ones it's clear there was a good improvement, especially considering this camera records 4 videos at same time (my current ones only record 2 videos). The performance at night has the most noticeable improvement, making easy to identify signals and license plates in the videos. The GPS unit that comes with it is the cherry on top as it provides location and speed in all videos, making it smooth the video synchronization. Another feature that I really liked is the OBD connector for power the unit. The old way to permanent connect the camera (using the fuse box connector wiring) was easy but a bit laborious depending on the car. This one is plug-and-play, and it can be easily disconnected when needed. Worth the purchase as it will provide greater peace of mind knowing everything is being properly (and better) recorded when driving around.

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.

My first day to use this dash cam this afternoon Im still learning it. I love the fact that i have cameras on the front. Rear and sides. If a car hits me from the side. Records it Parking mode. Records if bumped

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.

I got this dash cam because I am going to college and I wanted to keep my car safe and have security while driving in a new area and it is perfect. Surprisingly easy to install.

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.

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!!!

After a full day of installing the unit, I had everything wired properly and set up. After downloading the app I could view all activity from my phone or PC. The following day I came out to the car and tried to view the actio it recorded. Once the app turned on I noticed the SSID was changes and the passcode wasn’t right. The perpetrators somehow logged into the device and slipped a % sign in the middle of the SSID. They changed the password so I was unable to log in to the camera. They also deleted all the files that caught them breaking in and erased them all from the app. This is NOT a device you want to use as a security device to be used specifically for catching break-ins or something that will protect the interior of the car. I’m puzzled as to how they bypassed my alarm to get into the car or how the SSID got changed along with the password. Simply put, after 2 days of having a working product, the bad guys figured out how to breach the app and change the settings while deleting everything that was recorded. Nonetheless it took another day to uninstall and returned it back to Best Buy. Nobody was savvy enough to know how to protect this from happening nor understood how they did it. Not worth the $368 nor the Time to install and uninstall within a 2 days period of having it NOT work and hackable within hours. DONT WASTE YOUR TIME OR MONEY ON THIS PRODUCT!

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.

I probably wouldn’t buy this product again as it goes off and has to reset itself while driving and sometimes it’s not recording all sided

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

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
