And a dashcam can help you keep a clear record of what happens on the road, no matter where you’re going, in case of an accident or dispute. This Prime Day, you can pick up the 70mai A810S for $134.99, reduced from $199.99. That's $65 in savings on one of the best dashcams for drivers who want clear 4K recording and coverage at both ends of the car. 70mai includes a 128GB memory card for good measure. Dual cameras provide complete coverage on your travels To provide complete coverage, the A810S’s front camera records in 4K for capturing details, such as license plates and road signs, while the rear camera keeps a view of traffic behind you. Credit: 70mai Unlike most 4K dashcams on the market, the 70mai A810S records clear and detailed 4K video during the day and, more importantly, at night, thanks to MaiColor Vivid Solution and Lumi Vision. It also features enhanced license plate recognition, which helps preserve important details in any condition. Buffered emergency recording is a standout feature worth mentioning. If another driver swerves into your lane before a collision, the lead-up can help explain what happened. The A810S saves up to 3 minutes before an incident and 30 seconds afterward, preserving that context. Important clips are automatically saved in an emergency folder, making them easier to find when you need them. A device that is at home in any vehicle The A810S has a compact design, so it can tuck behind your rearview mirror without dominating the windshield. There’s a built-in screen, too, so you can review a clip directly on the camera.

With the optional hardwiring kit, you can receive app alerts and have incident footage uploaded to the cloud, alongside 24-hour parking monitoring. Uploaded recordings remain accessible even if the camera is damaged or removed. At $134.99, the 70mai A810S is an affordable way to start recording your drives, with a rear camera and a 128GB memory card already included. If you’ve been waiting for a deal on a 4K dashcam, this is a good chance to snag one for much less.
