Advanced Features
1. Loop Recording & Evidence Protection
The dash cam records video in continuous loops. When the SD card is full, the oldest unlocked video files are automatically overwritten by new recordings. Important footage can be manually locked or automatically locked by the G-Sensor to prevent overwriting.

2. G-Sensor & Accident Lock
The built-in 3-axis G-Sensor detects sudden movements or impacts. In the event of a collision, it automatically saves and locks the current video file, preventing it from being overwritten during loop recording. You can also manually lock a video by pressing the designated lock button.
3. 24H Parking Monitor
When your vehicle is parked, the parking monitor feature provides continuous protection. If the dash cam detects vibration or impact, it will automatically power on and begin recording. This feature requires a continuous power supply (e.g., hardwire kit, sold separately) to function for 24 hours.

These features work together to improve image clarity and color accuracy, ensuring clear recordings even in low-light conditions or at night, capturing details like license plates.
