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 Sony’s latest Starvis 2 sensors, and right now it’s marked down to $225.62 from $399.99. That’s serious hardware at a price that used to only buy you a basic single-channel camera.
What you’re 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 you’re 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.
Those Starvis 2 sensors are built for low light, so night footage doesn’t completely fall apart once you’re off a brightly lit street. Paired with HDR and the brand’s “Night Vision 2.0” tuning, the F77 is designed to keep moving objects and plates readable under headlights and streetlights instead of turning them into glowing blobs.
On the usability side, you’re 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. There’s also a hardwire kit for 24/7 parking mode, so the camera can keep watch when your car’s parked.
Why it’s 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, you’re 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 isn’t just a tiny camera on your windshield — it’s a full protection system for your car.
The bottom line
If you’ve 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. For $225.62 instead of $399.99, you’re getting dual 4K recording, strong low-light performance, built-in 128GB storage, GPS, parking mode, and fast 5.8 GHz Wi-Fi in one package. As a long-term upgrade for both daily driving and road trips, it’s hard to argue with that value.
