4.2.2 Loop Recording
The dash cam features loop recording, which automatically overwrites the oldest unlocked video files when the memory card reaches its full capacity. This ensures continuous recording without the need for manual deletion. Locked emergency files are protected from being overwritten.
| Memory Card Size | Recording Time |
|---|---|
| 32GB (Included) | 2 Hours |
| 64GB | 4 Hours |
| 128GB | 8 Hours |
| 256GB | 16 Hours |
| 512GB (Max Support) | 32 Hours |

4.2.3 G-Sensor (Emergency Lock)
The built-in G-Sensor automatically detects sudden impacts or collisions. When triggered, it locks the current video file, preventing it from being overwritten by loop recording. This ensures critical incident footage is preserved. The G-Sensor sensitivity can be adjusted (Off, Low, Medium, High) in the settings.

4.2.4 Time-Lapse Recording (24-Hour Parking Monitoring)
The M50 Dash Cam supports time-lapse recording, which efficiently compresses 30 minutes of video into a shorter file. This feature is ideal for 24-hour parking monitoring, conserving memory while providing continuous surveillance of your parked vehicle. An ACC hardwire kit (sold separately, ASIN: B0CZDMML9Y2) is required to enable 24-hour parking monitoring.
