WOLFBOX G840S 12" 4K Mirror Dash Cam
Product description
The WOLFBOX G840S mirror dash cam blends a large 12 inch display with a 4K front camera and a 1080p rear camera to improve visibility and record critical moments on the road. This setup aims to cut blind spots, provide clear daytime and night footage, and offer connected features like GPS tracking and 5.8GHz Wi‑Fi for easy playback and sharing.
Highlights

The oversized 12 inch screen gives about one and a half times the viewing area of a typical mirror, so you see more of the road and less blind zone. The front 4K UHD lens captures fine detail at 2160p while the rear 1080p camera covers reversing and rear traffic. Built in WDR and HDR help balance tricky lighting and a low reflectivity LCD reduces daytime glare. The pack includes a 32GB card and a GPS antenna for location overlay and speed readouts, and the WOLFBOX app lets you connect by Wi‑Fi for live view and quick clips.

Why it’s worth it



The G840S focuses on usable visibility and reliable recordings, especially if you often drive in mixed light or park in busy areas. Night vision, multi‑glass lenses, and HDR/WDR work together to keep footage usable when glare or low light would otherwise wash out details. Note that parking monitoring requires a hardwire kit to keep the unit powered while parked.
Best use cases

You’ll appreciate this mirror cam if you want a bigger display to monitor both front and rear at once and need higher resolution front footage for evidence or insurance purposes. It’s a solid fit for drivers who value connected features such as GPS tracking and quick phone access to recordings through an app.
Care & maintenance
Keep the mirror surface clean with a soft microfiber cloth and avoid abrasive cleaners. For consistent parking surveillance, install a dedicated hardwire kit through a professional to prevent battery drain and to maintain warranty coverage.
