File Locking Function Description - Rhoson DV Series User Manual

3.File Locking Function Description

The host can manually lock file and may trigger an automatic file lock due to external impact.
Automatic Lock:
When the built-in Triple-axis Acceleration In-sensor of the host detects excessive acceleration, it will automatically determine that an impact
accident has occurred and thus immediately lock the file.
Manual Lock:
Please press the button and hold for 3 seconds to keep the files that are currently being recorded from overwritten. At this time, the red
light will flash slowly, indicating that the recording function is locked.
File Locking Reference:
The lock file is based on the "file" instead of the recording time. For example: the exact trigger file is a trigger file plus 30 seconds from the
start point to the trigger point.
Take the 3 minutes file as an example:
Note: Locked files can occupy up to 30% of the SD card's capacity. When this capacity is exceeded, the oldest locked files will be overwritten.
