GKU 4K+4K Front and Rear Dash Cam with STARVIS 2 IMX675, 5.8GHz WiFi 6, GPS & 24/7 Parking Mode (3" IPS, 128GB included)
Product description
Key takeaways
If you want a front-and-rear dash cam, this GKU model is built around capturing more of what’s happening around your vehicle, not just what’s directly ahead. The headline is dual recording at up to 4K+4K, paired with an HDR/WDR approach for night and tricky lighting. Add the built-in GPS and 5.8GHz WiFi 6 for faster transfers, and it starts to make sense for drivers who actually want usable evidence after an incident.
That said, there are a couple of “read the fine print” points. The parking monitoring feature needs a dedicated hardwired kit (not included), so you’ll need to budget time and parts if you’re serious about 24/7 coverage. Also, while it claims you can cover lots of road context (the front angle is 170° and the rear is 150° on paper), results always depend on how well the cameras are aimed and how your car’s interior lights up at night.
It’s a strong fit if you’re looking for a mid-range-spec dual-channel setup with WiFi for reviewing footage and GPS for tagging speed/route. It may not suit you if you want a “fit-and-forget” parking solution without any extra wiring.
Where it shines
The most practical reason to consider this dash cam is the combination of dual recording and quicker video access. With both front and rear cameras recording in 4K, you’re less likely to end up with an incomplete view when something happens at an intersection, during a lane change, or when another vehicle appears from behind.
The WiFi 6 detail matters more than it sounds: the listing notes downloads of up to 20MB/s via the GKU GO app on iOS and Android. In everyday use, that translates to fewer “waiting around” moments when you want to check a clip, save it, or share it while the incident is still fresh.
For night driving, it leans on Sony STARVIS 2 (IMX675) and HDR/WDR-style processing, plus apertures mentioned as F1.5 front and F1.8 rear. It’s the kind of spec mix that’s meant to hold detail better when the street lights are bright but the rest of the scene isn’t.
And when you’re parked, the idea is to keep an eye on events. The dash cam is described as offering 24-hour parking monitoring with low-power time-lapse mode after the vehicle is switched off, plus pre-recording (it caches key footage) and collision-triggered locking of footage.
What you’ll notice day to day
This model is designed around “capture, then retrieve”. Loop recording continuously overwrites the oldest footage when the SD card reaches capacity, which is exactly what you want for a dash cam that’s meant to record all the time without manual housekeeping.
It also includes a G-sensor that locks a recording when it detects a collision or abnormal impact. That’s useful because it reduces the chance that important evidence gets overwritten.
The built-in GPS is another detail that can be genuinely helpful in real arguments or insurance discussions, because the listing says it records speed and route data.
There’s also an on-device element: a 3" IPS screen for viewing and basic review, which can be more convenient than relying entirely on the app.
Finally, it supports intelligent voice control with 9 voice commands (for example, turning audio on/off and taking photos). That’s the sort of feature that can reduce fiddling with the screen while driving—though, like any voice system, it’s still best used when you know what the car is doing and you speak naturally.

Who it’s for (and who should look elsewhere)
It’s a good fit if you mainly want two things: broader coverage around your car and easier footage retrieval. If you’ve ever had a “hindsight problem” (the front camera didn’t show the full story, or you needed clips quickly), dual front/rear recording plus WiFi transfer is where this model tries to solve that.
It also makes sense if you do a mix of city driving and darker routes, because the STARVIS 2 IMX675 + HDR/WDR positioning is clearly aimed at night visibility.
It may not suit you if you’re not willing to install extra hardware for parking monitoring. The listing explicitly notes that 24-hour parking mode requires a dedicated hardwired kit (not included). If your priority is strictly a simple, minimal installation with no wiring plan, you may want to skip this feature set.
Getting the most from it
Before you buy, it’s worth checking two practical areas. First, confirm you’re comfortable installing (or arranging installing) a dedicated hardwired kit if you want the 24/7 parking monitoring. Second, take a moment to plan where the cameras will sit and how they’ll be angled—wide lenses are great, but misalignment can blur the story you’re trying to capture.
On a normal day, you’ll likely use the screen for quick checks and rely on the app when you need to pull a clip fast. For example, if you return to the car after a minor scrape in a car park, you can open the app, browse the locked footage (triggered by the G-sensor) and save/share what you need while you’re still on site.
Final verdict
Should you buy it? Worth considering if you want a dual front and rear dash cam that focuses on broad coverage, quick WiFi transfers (5.8GHz WiFi 6 with up to 20MB/s stated), and added context thanks to built-in GPS. It’s also a sensible pick if night performance is part of your decision, given the STARVIS 2 IMX675 sensor and HDR/WDR positioning.
Skip it if you mainly care about parking monitoring without extra installation effort, because the 24-hour mode relies on a dedicated hardwired kit that’s not included. And if you’re expecting a fully premium experience in all conditions, it’s fair to say this sits as a spec-forward dual setup—good value on paper, but still dependent on fitment, aiming, and lighting in your own driving.
