4.5 Parking Monitoring & G-Sensor
When connected to an optional hardwire kit (ASIN: B0CRHJQ3WQ), the dash cam can provide 24-hour parking monitoring using time-lapse recording.

4.6 Loop Recording
The dash cam utilizes loop recording, which means it continuously records and overwrites the oldest video files when the MicroSD card is full. This ensures that you always have the most recent footage available.

Equipped with Super Night Vision and HDR (High Dynamic Range) technology, the S1 Ultra delivers clear and detailed video recordings even in challenging low-light or high-contrast conditions.
