Q: Does the parking feature utilize motion sensor activation? If so, will it send an alert to my app?
A: Yes, it uses motion sensor, but will not send you a notification when triggered.
A: Yes, it has 4 cameras on this unit including front and back. It does not record 24/7. When the car is off, it will only record when vibrations or motion is detected.
Q: Will this kill my battery or does it detect when it's running low?
A: No, if voltage goes to low, it disconnected automatically
Q: I don’t have a cigarette lighter. I use usb c. Can I use this in my car?
A: Hello, Unfortunately, you would be unable to power the dashcam effectively through the USB/USB C port in your vehicle. The problem with USB ports is that most USB ports in vehicles do not emit sufficient voltage to power our dashcams. USB ports in vehicles or computers typically emit around 5 to 6 volts of power which would not be sufficient to be used with our dashcams. Thus leading to random restarting, not recording properly or simply not turning on at all. Hope this answers your question!

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.
