70mai 4K A810 (Front + Rear)

Should you buy the 70mai 4K A810?

The 70mai 4K A810 (Front + Rear) is the dash cam for someone who wants a real 4K front camera, a rear camera in the box, and a price that stays under $200 without feeling like a compromise. It sits at the top of our dash cam category because it does the mainstream job well: a Sony STARVIS 2 sensor, HDR, GPS, and a screen you can actually check. If you drive for rideshare and need cabin footage, the Vantrue N4S is the better tool. For everyone else, this is the default.

Where it earns its score

• Value is its best factor. A 90 Value score reflects a 4K HDR front camera plus a 1080p rear unit at $159.99, commonly discounted to $125 to $150.
• Sony STARVIS 2 IMX678 sensor. The same front sensor found in dash cams costing $100 more, recording 4K at up to 60 fps.
• Built-in GPS and a 3-inch screen. Speed and location are stamped on footage, and the IPS display lets you confirm framing without the app.
• Parking coverage that thinks. Smart Parking Guardian uses AI motion detection; the optional UP04 hardwire kit unlocks 24-hour monitoring.

What to know first

• Warranty is the weakest ViperScore factor. At 55, coverage is short; register the unit and keep your receipt.
• The rear cable is captive. The RC12 rear camera uses a proprietary cord that does not detach.
• No horizontal adjustment up front. The front camera pivots vertically only, so mount placement matters on the first try.
• Extras cost extra. The 4G LTE module and the hardwire kit are both add-on purchases.
