Most dash cams still top out at 1080p or give you a sharp front view and a muddy rear feed. The F77 Starvis 2 4K+4K Dual IMX678 dash cam goes much further: it records in 4K from both the front and rear, uses Sonys latest Starvis 2 sensors, and right now its marked down to $225.62 from $399.99. Thats serious hardware at a price that used to only buy you a basic single-channel camera.

　　What youre getting

The headline feature on the F77 is true dual 4K recording. Both the front and rear cameras use Sony IMX678 Starvis 2 sensors, so youre not stuck with a 4K/1080p split. You get detailed, 16MP footage on both ends of the car, which makes a real difference when you need to read plates or zoom in on a specific moment in traffic or a parking lot.

On the usability side, youre getting built-in 128GB eMMC storage instead of a cheap microSD card, 5.8 GHz Wi-Fi for faster clip transfers to your phone, a 4-inch touchscreen, voice control so you can lock clips without taking your hands off the wheel, and GPS to log speed and location. Theres also a hardwire kit for 24/7 parking mode, so the camera can keep watch when your cars parked.

　　Why its worth it

At full price, the F77 sits in enthusiast territory. At $225.62, it suddenly looks like a very solid midrange buy with high-end specs. A lot of dual-channel setups in this bracket still do 4K front and 1080p rear, or skip things like built-in storage and GPS. Here, youre getting dual 4K, better night performance, and more polished hardware and software than the usual budget dash cam.

If you drive a lot at night, run ride-share, or just want rock-solid evidence if something goes wrong, those Starvis 2 sensors and the upgraded night vision are worth paying for. Add in the always-on parking monitoring and faster Wi-Fi offloads, and this isnt just a tiny camera on your windshield its a full protection system for your car.

If youve been waiting for a serious dual 4K dash cam to drop into a more reasonable price range, this F77 Starvis 2 deal hits the sweet spot.

As a long-term upgrade for both daily driving and road trips, its hard to argue with that value.
