70mai A810 Lite-RC21-64GB 4K Front and Rear Dash Cam with HDR

Drivers looking for coverage from both ends of the car can record with the 70mai A810 Lite front-and-rear dash cam. Its front camera captures 4K video, while the rear camera records in 1080p.

What it works with

Designed for cars, the system pairs its front-facing camera with the included RC21 rear camera for dual-channel recording. A smartphone connects through the 70mai app, where you can preview and play back footage, adjust settings, review GPS data, and manage video files. The built-in 5GHz Wi-Fi 6 supports wireless video transfer, so you can access clips on your phone without removing the microSD card. 4G LTE support adds remote-access capability for connected use.

Compared with a front-only dash cam, this setup also records the view behind the vehicle. That can be useful on a daily commute, a road trip, or when you want front and rear footage available for later review. The 140° front and 130° rear views provide broad coverage from both cameras.

Usage tips

For everyday driving, voice control provides a hands-free way to use supported commands, while loop recording manages ongoing capture by overwriting older files. Emergency locking and G-sensor detection help preserve footage associated with an impact. GPS can add route, speed, and location details to playback, giving recorded clips more context.

For parked-car monitoring, choose between impact-triggered recording and time-lapse recording. Parking mode requires a compatible UP03, UP05, or UP06 hardwire kit. The camera’s charging cable should connect to the port marked DC/IN. The included 64GB card provides storage to get started, with support for microSD cards up to 512GB.

Buyers often praise the front camera’s clear, detailed footage and find the app straightforward to use. Feedback on connectivity, cable length, and mounting adhesion is mixed, so plan the camera placement and cable route around your vehicle’s layout.

Before you decide

What resolution do the two cameras record? The front camera records in 4K, and the included rear camera records in 1080p, providing footage from both directions.

Can I view recordings on my phone? Yes. Use the smartphone app to preview, play back, download, and share recordings over the camera’s 5GHz Wi-Fi 6 connection.

What do I need for 24-hour parking mode? Parking mode requires a compatible UP03, UP05, or UP06 hardwire kit. It supports G-sensor impact recording and time-lapse monitoring.

Should you buy it?

Choose the A810 Lite if you want one car camera system for 4K front footage, 1080p rear coverage, and app-based video access. HDR night vision, GPS tracking, and parking-mode options make it suited to drivers who want useful context in their recordings both on the road and while parked.
