Pros
- 4K front camera delivers exceptional detail for license plates and road signs.
- Extra-large 12-inch screen improves rear visibility and reduces blind spots.
- Built-in GPS and WiFi provide real-time tracking and easy app connectivity.
- Superior night vision with WDR/HDR ensures clear footage in challenging light.
- 24-hour parking monitor offers continuous surveillance when parked.
Cons
- Parking monitor requires a separate hardwire kit, which is not included.

The WOLFBOX G840S is a feature-packed 12-inch mirror dash cam designed for drivers who want to upgrade their vehicle's safety and recording capabilities. It replaces your standard rearview mirror with a large 2.5D curved screen that integrates seamlessly into your car's interior. This product is ideal for those who frequently drive in busy areas, want to capture high-quality footage, or need reliable parking surveillance.
Standout features include the front camera's 4K UHD resolution (2160p) paired with a 1080p rear camera, providing sharp, detailed video for both front and rear views. The 12-inch display is 1.5 times larger than a typical mirror, significantly reducing blind spots. Real-time GPS data is displayed on the screen, and WiFi connectivity lets you control the camera and share videos via the WOLFBOX app. Night vision is excellent thanks to WDR/HDR technology and a low-reflectivity LCD that minimizes daytime glare.
The build quality feels solid, with a sleek black design that matches most vehicle interiors. Installation is straightforward for the mirror mount, but the parking monitor feature requires a hardwire kit (sold separately). The 32GB memory card is included, so you can start using it right away. The interface is intuitive, and the split-screen function allows simultaneous viewing from both cameras.
One drawback is that the parking mode's hardwire kit is not included, adding extra cost and effort for those who want 24-hour monitoring. Additionally, the large screen might take some getting used to, as it can be slightly reflective in direct sunlight despite the anti-glare coating. As a relatively new product, there are few user reviews to gauge long-term reliability, but the brand offers a 12-month guarantee.
Overall, the WOLFBOX G840S delivers impressive 4K clarity, a massive display, and useful GPS/WiFi features at a competitive price point. It is a strong choice for drivers who prioritize safety, want to document their journeys, and need a versatile dash cam that doubles as a backup camera. With its thoughtful design and robust feature set, it earns a solid recommendation for most vehicle owners.
