The GKU 4K Dash Cam Front and Rear, 1.5" IPS Screen: What You're Actually Getting
Most of the time a dash cam just sits on your windscreen doing nothing interesting. Its whole job is to be ready for the ten seconds when something goes wrong — a driver pulling out without looking, a shunt at the lights, a scrape in a car park while you were inside a shop. The GKU 4K Dash Cam Front and Rear, 1.5" IPS Screen is built around that job: front and rear cameras recording continuously in 4K front / 1080P rear, so you have footage rather than a guess about who did what.
What's actually different about this one
The front camera handles the road ahead in 4K, while a second lens on the rear windscreen records in 1080P at the same time. That matters because a meaningful share of insurance disputes involve what happened behind the car, not in front of it — a front-only camera simply can't help with those.
After dark, resolution alone doesn't guarantee usable footage — a weak sensor either blows out under headlights or loses everything to shadow. This camera includes night vision with WDR processing that balances bright and dark areas in the same frame, so plates and faces have a better chance of staying readable once the sun goes down.
Who it suits
24H parking mode lets the camera wake itself on motion or impact while your car is parked, running from its own battery or supercapacitor for a limited window. For extended, always-on parking coverage you'd want to add a hardwire kit separately.
The short version
A GPS module timestamps every clip with your location, route and speed, which adds useful context if you ever need to explain exactly where and when something happened. The 5GHz WiFi connection pairs with a companion phone app, so you can pull clips straight to your phone rather than removing the memory card every time you want to save something. At £132.98, the GKU 4K Dash Cam Front and Rear, 1.5" IPS Screen is a straightforward way to get real evidence on your windscreen without needing to research every spec sheet on the market yourself.
