Design And Display: A 12″ Mirror Monitor Built for Drivers
Large, High-Resolution Mirror Display
The centerpiece of the system is the 12-inch mirror monitor. It performs double duty: functioning as a rear-view mirror while displaying real-time video, playback, and backup camera feed.
Key display attributes:
- Large and clear viewing area
- Easy-to-read interface
- Automatic brightness adjustment for day/night use
The G840S’s mirror monitor transforms your existing rear-view mirror into a high-definition smart display without obstructing your normal driving view.
4K Front Camera: Ultra-Clear Recording
Crystal-Clear Front Footage
The front camera of the WOLFBOX G840S captures 4K resolution footage — one of the highest quality levels offered in consumer dash cams. This elevated video clarity provides:
- Detailed incident recording
- Clear license plates and road signs
- Improved evidence quality for disputes or insurance claims
Whether you’re driving on bright highways or shaded city streets, the front camera’s high pixel count ensures your recordings retain sharpness and detail.
Night Vision And Low-Light Performance
Reliable Recording After Dark
Nighttime footage can make or break a dash cam system. The G840S incorporates enhanced low-light performance and night vision technologies, including:
- Improved light sensitivity
- Noise reduction
- Balanced exposure
This allows the dash cam to capture usable, detailed video even in low-visibility conditions such as poorly lit roads or late-night drives.
Backup Camera: Enhanced Safety And Parking Assistance
Seamless Rear-View Integration
A major advantage of the G840S system is its dedicated backup camera. This camera integrates directly into the mirror display, offering:
- A wide-angle rear view
- Real-time guidance lines
- Better spatial awareness when reversing
This feature is especially helpful in tight parking situations, crowded lots, and when towing trailers or navigating narrow streets.
Parking Mode And Motion Detection
Security Even When Parked
The WOLFBOX G840S includes an intelligent parking mode, which enables the system to:
- Record when motion is detected near the vehicle
- Capture vibrations or impacts while the car is parked
- Preserve evidence in hit-and-run or parking lot incidents
This passive monitoring increases vehicle security and provides peace of mind when leaving your car unattended.
User Interface And Controls
Intuitive Menu and Navigation
WOLFBOX designs the system’s interface with user experience in mind. The menu is:
- Easy to navigate
- Responsive to touch (if equipped)

Installation And Setup
Straightforward Installation Process
While advanced in features, the G840S system is designed for DIY installation. Key points include:

Most users find the setup process clear and manageable, even without professional installation — though professional help remains an option.
GPS Tracking And Speed Logging (Optional)
Enhanced Data for Driving Records
Some configurations of the WOLFBOX G840S include GPS logging. This feature:
- Records your route and speed
- Time-stamps footage for evidence
- Helps with trip tracking and analysis
This capability boosts the system’s value for drivers who want data-rich recordings.
Video Playback And Storage Options
Flexible Recording Files
The dash cam system supports common storage formats and memory cards (usually up to 256GB or higher), enabling:
- Loop recording
- Automatic file overwriting
- Easy playback via the display or external devices
This flexibility ensures important footage is stored reliably and retrievable when needed.
Real-World Performance And Reliability
Daily Driving Conditions
In everyday use, the G840S delivers consistent performance, capturing crisp footage with minimal issues. Its wide-angle lenses document a broad field of view, proving valuable for:

Long Trips And Extended Hours
For long drives, the large display and reliable recording make this system a standout choice. Many users report simplicity and confidence when navigating unfamiliar routes.
