3.4 Micro SD Card Insertion

4. Operating Instructions
Once installed and powered on, the STINGER STR4K offers various display and recording modes.
4.1 Display Modes
The 9.66" full-screen 4K UHD display allows you to customize your view:
- Front View: Displays only the feed from the front camera.
- Rear View: Displays only the feed from the rear camera.
- Split View: Shows both front and rear camera feeds simultaneously.
- Display Off: Turns off the screen while recording continues in the background.
These modes are useful for specific situations such as parking, changing lanes, or navigating tight spaces, helping to minimize blind spots.
4.2 Recording Functionality (DVR)
The built-in DVR continuously records footage from both cameras onto the Micro SD card. Key features include:
- Loop Recording: Older files are overwritten by new recordings when the memory card is full.
- G-Sensor: Automatically detects sudden impacts or collisions and locks the current footage to prevent it from being overwritten, providing crucial evidence.
- Parking Monitoring: When the vehicle is parked, the system can continuously monitor surroundings and save storage space with time-lapse footage. This feature helps protect your vehicle by recording events even when you are away.
Around-the-clock parking monitoring with G-Sensor for heavy impact recording.
DVR functionality stores your recordings on the included 64GB Micro SD card.
4.3 GPS Data
The included GPS antenna tracks crucial driving data such as direction, speed, and position. This information is embedded in the video footage and can be vital evidence in the event of an accident.

To ensure the longevity and optimal performance of your STINGER STR4K, follow these maintenance guidelines:
- Cleaning: Gently wipe the mirror screen and camera lenses with a soft, lint-free cloth. Avoid abrasive cleaners or solvents that could damage the surfaces.
