A:Answer By default, the dēzlCam immediately starts recording video when it turns on. It continues recording, overwriting the oldest, non-saved video until it turns off. The device records continuously until the device is turned off or video recording is disabled. In addition, the dēzlCam uses a sensor to detect possible accidental collisions and saves video footage before, during, and after the detected event. You can also manually save the video at any time.
