Loop Recording automatically overwrites the earliest file & records over it when storage fills up. With G-sensor enabled, the dash cam will automatically lock the current footage to prevent video from being overwritten when it detects a sudden shake/collision, which ensure important footage is protected . With the built in variable G-sensor, even when your car is parked, the dash cam will start recording video if your car is impacted (the impact level can be changed in settings) for up to 3 minutes. The Dash cam has a 16GB micro SD card included & supports additional cards with up to 128 GB of capacity. You can view the recorded videos (.MOV) by taking the memory card out of the dash cam & playing the content in compatible device or playback on the 3'' LCD screen.
