Customer Ratings & Reviews

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.

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'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!

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.

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.

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!!!

Best Buy did a very good job installing my rexing dashcam

The BBY-R4-RD dash cam delivers excellent all-around coverage with clear front, rear, and interior video, day or night. Installation was easy, and the wide-angle lenses capture everything around the vehicle. The built-in radar is a standout — helpful for parking and detecting nearby movement without false alerts. Reliable recording, parking mode, and simple app access make this a solid, worry-free upgrade for safety and security. Highly recommended.

Very clear picture and easy set up. User friendly. I love that it has three cameras and the rear camera.

And other good Rexing product, is my 3st dashcam, good quality and easy installation. Cover every angle.

This dash cam has been excellent from day one. Installation was quick and straightforward, and it’s been reliable every time I’ve used it. The video quality is clear, the 360° coverage is a huge plus, and having an app to easily view and manage footage makes everything super convenient. Overall, a great all-around dash cam that does exactly what it’s supposed to do.

Best dashcam nice and work properly easy to install proper image easy to connect with phone

recently purchased the Rexing R4 for my truck, and I’m very pleased with it. I’ve been a Rexing customer for about six years now, starting with the Rexing V1, which was an excellent camera. A few years ago, I was involved in a wreck where the other driver tried to deny fault. Fortunately, I had clear footage, and once I sent it to his insurance company, there was no room for argument. That experience made one thing certain for me — I will never drive without a dash cam again. These cameras are useful for so many situations. The GPS feature is especially helpful, as it can track your speed in case you ever need to prove how fast you were going during an accident or a traffic stop. That feature can be turned on or off based on your preference. Overall, I’m very satisfied with my purchase and will continue to be a loyal Rexing customer.

Pretty sweet cam! Great quality and I love that it is so easy to use and install. I feel safer with this and recommended it, especially if you drive a lot!

This dashcam is very good to capture all four sides, means 360 surround view. Picture quality is good. Only one thing I hate is that it does not come with memory card, you have to purchase it separately.

This is very advance camera with all around vision and high end picture quality. I was looking for something like this to install in my brand new Lexus TX-350 and happy with the purchase as easy installation and friendly app to access all the videos.

I recently installed the Rexing R4-RD Dash Cam in my vehicle, and it’s been working really well. The build feels solid and well-designed, and the comprehensive coverage gives me real confidence on the road. Would definitely recommend!

Love the camera. I've been using Rexing products for years. They are simple to install and produce quality images. It's great that Rexing is including an OBD power source. Thanks.
