This is critical for preventing unintended battery depletion during extended parking periods.
-
Buffered Recording
Some cameras offer buffered recording in parking mode, where they continuously record a short loop of video in the background. When motion is detected, the camera saves a longer clip that includes a few seconds before the motion event occurred. For example, the camera might constantly record a 15-second loop, saving a 30-second clip that includes 10 seconds before and 20 seconds after the triggering event. This feature ensures capturing the lead-up to an incident, providing valuable context.
-
Impact Detection (G-Sensor)
Parking mode can also be activated by the integrated G-sensor, which detects sudden impacts or vibrations. If the sensor registers a significant jolt, the camera will begin recording, even if no motion is detected in the field of view. An instance could be a vehicle being bumped in a parking lot. The G-sensor triggers recording, capturing footage of the incident and potentially identifying the responsible party. This independent trigger mechanism enhances the camera’s ability to capture critical events.
The effectiveness of Parking Mode Activation significantly enhances the value of a dash camera equipped with motion sensor capabilities.
