A New Benchmark for All-Around
Dash Cam Protection
See more of what happens around your car. Front and rear cameras capture the road ahead and traffic behind in true 4K, while two 1080P side cameras record vehicles alongside and bumps while parked. All four record together, giving you more angles to understand an incident.

Wider Coverage.
One-Tap Switching.
Quickly switch between front, rear, left, and right views in the 70mai App. See what a single angle may miss, and get a fuller picture of how an incident unfolded.
True 4K, Clearer Proof, Front & Rear.
Adding side cameras shouldn't mean losing detail where it matters. F800 maintains native 3840 × 2160 recording at both the front and rear, even when all four cameras are active. Preserve finer details in license plates, road signs, and the moments you may need to review.

Rear Camera
Clarity Beyond Resolution. Day and Night.
Beyond true 4K, both front and rear cameras combine an f/1.55 large aperture, HDR, and a wide 140° field of view to capture more of the road, preserve clearer details in low light, and balance exposure in high-contrast scenes.
Customizable Protection via
180° Rotatable Side Cameras
Choose what you want to keep in view. Each 1080P side camera rotates horizontally through 180°, allowing you to adjust for side-view recording or turn it toward the cabin. Adapt your setup for everyday driving, family trips, or interior monitoring.
