5.3 Key Features
- Loop Recording: The dash cam continuously records video. When the SD card is full, the oldest video files are automatically overwritten by new recordings. Recording segments can typically be set to 1, 2, or 3 minutes.
- G-Sensor (Emergency Video Lock): In the event of a sudden impact or collision, the built-in G-Sensor automatically detects the event and locks the current video segment, preventing it from being overwritten by loop recording.
- Parking Modes: The dash cam offers two parking modes to monitor your vehicle when parked (requires Type-C port hardwire kit, ASIN: B0BNTLSMJ3, sold separately, for 24/7 monitoring):
- Time-Lapse Parking Mode: Records video at a low frame rate to conserve storage space and power, capturing extended periods of activity.
- Impact Detection Parking Mode: Records a short video clip when an impact is detected while the vehicle is parked.
- Night Vision: Equipped with an F1.8/6 glass aperture lens and image sensor, combined with WDR technology, the dash cam enhances video clarity in low-light conditions and balances light/dark changes.
