Our take on the Rexing S3 3-Channel Wi-Fi Dash Cam

The Rexing S3 is a three-channel dash cam that records the road ahead plus front and rear cabin views, so it covers rideshare trips and rear-end collisions from one unit. It adds built-in GPS, a G-sensor, Wi-Fi, loop recording and a parking monitor with motion detection, and uses a supercapacitor instead of a battery for better heat tolerance. The best new price is $159.99 at Best Buy as of November 5, 2026, and only one store lists it new, so there is little price competition to shop around.

Pros

  • Built-in GPS logs speed and location with the video
  • 170-degree front lens and seven-layer glass optics
  • Parking monitor with motion detection and 24/7 time-lapse recording
  • Wi-Fi lets you pull clips to a phone without a card reader
Cons

  • Three-channel recording fills a card faster than a single-cam setup
  • Cabin and rear cameras add wiring work to the install

Questions and answers

Does the Rexing S3 record the cabin as well as the road?
Yes. It is a three-channel cam: one camera faces the road, one faces the cabin and one covers the rear. That makes it suited to rideshare drivers who want a record of passengers.
Is the Rexing S3 worth $159.99?
At $159.99 at Best Buy as of November 5, 2026, you get three cameras, GPS and a supercapacitor in one unit, which is a fair package for that money. Only one store lists it new, so compare against two-channel cams before deciding.
Does it come with a memory card?
No. It records to a microSD card that you supply. Buy a high-endurance card rated for continuous video, since three channels write a lot of data.
Will it survive hot summers parked outside?
It uses a supercapacitor rather than a lithium battery, which is the more heat-tolerant design for dash cams. Rexing also rates it for enhanced temperature resistance in harsh climates.
Can I watch footage on my phone?
Yes. Built-in Wi-Fi connects the cam to the Rexing app so you can view and download clips. You can also pull the card and read it on a computer.
Does it record while the car is parked?
Yes, with the parking monitor and motion detection enabled. That usually needs a hardwire kit so the cam keeps power with the ignition off.
