For what memory chips cost these days, they should record continuously anytime the camera (accelerometer in the camera) detects motion within the previous 10 minutes. If they’re on-body, or in a moving car, they should be recording.
The “save” button could work the same: mark 30 seconds before until “save” is deactivated to be “do not delete this for rotation” - but otherwise, save everything anyway, only rotate out after 2TB of memory card is full, and download at the end of every shift.
Better still, download continuously to the car and 5G it to a cloud server where the department can’t delete it.
