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.
