WOLFBOX G840S 12" 4K mirror dash cam with GPS

This 12-inch mirror dash cam from WOLFBOX combines a large HD display with front and rear recording to help drivers with clearer footage and easier reversing. It records up to 2160p at the front and includes night-vision improvements and GPS, making it useful for long drives, urban parking and fleet vehicles that need continuous monitoring.

Key Points

The oversized 12-inch low-reflectivity LCD gives a wider field of view that reduces blind spots for both driving and reverse manoeuvres. The front camera records in 4K Ultra HD 2160p according to the manufacturer, while a paired rear camera captures supporting footage for incidents or parking. The unit supports 5.8GHz WiFi for faster, less congested wireless connection to a smartphone app, which allows real-time viewing and video download. A 32GB microSD card is included and the system accepts cards up to 128GB, so recording can begin straight away. Consider that the app experience and WiFi range will depend on local signal conditions and smartphone compatibility.
