1. WOLFBOX G840S Mirror Dash Cam Front and Rear: Editor's Choice
The WOLFBOX G840S is a mirror-style dash cam that fits over the existing rear-view mirror and turns it into a large touchscreen display. It records the road ahead through a front lens and the view behind through a separate rear camera, giving a streamlined two-camera setup without a unit hanging off the windshield.
Real-world performance
Verified owner feedback highlights the big, bright touchscreen as the headline feature, making live view and clip playback easy at a glance. The wide field of view is praised for rear awareness, and many drivers like that the mirror layout keeps the cabin uncluttered. A recurring note is screen glare in strong sunlight, which some owners manage by adjusting brightness and angle.
Specs and build
This is a dual-channel mirror system with a front lens built into the mirror body and a wired rear camera. It uses a full touchscreen interface, mounts with straps over the factory mirror, and offers a wide viewing angle. Loop recording and on-screen playback are included for quick incident review.
Who it suits
The G840S suits drivers who want a clean, integrated look and a large screen for live view and reversing help. It is a good fit for people who dislike a separate camera box on the glass and want the mirror to do double duty.
Who should consider other options
Drivers who are sensitive to screen glare or who prefer to keep their original optical mirror untouched may want a traditional windshield-mounted cam instead. Anyone who rarely uses the live mirror view may not need the larger display.
- Mirror design that mounts over the standard rear-view mirror
- Large touchscreen for a clear live view and easy playback
- Front and rear cameras for full coverage of the car
- Wide field of view that opens up the scene behind the vehicle
Pros: Big, responsive touchscreen that is easy to read; Mirror form factor keeps the cabin tidy; Front and rear coverage in one streamlined unit; Wide view helps with reversing and rear awareness
Cons: Some drivers see glare on the screen in bright sun; It covers the standard mirror, which takes adjustment; Mounting straps and angle need careful setup
