The GX300 offers a few parking recording modes to choose from: Motion Detection, Low Framerate recording, and Smart Time Lapse recording.
If you choose Motion Detection, impact recordings are buffered - meaning you will get 10 seconds of pre-trigger in addition to after-trigger footage. Motion detection and G-sensor impact sensitivity levels can be customized in the dash cam’s settings menu. For other parking recording modes, a 30FPS after-trigger recording will be saved.
When you re-enter the car from parking mode, a voice notification lets you know how many impacts were detected in parking mode (if any). A Parking Mode Summary will be available via the FineVu mobile app.
