The Onn dual 3" LCD dash cam with a 120 degree wide angle lens ensures wider coverage of surroundings and automatically records 1080p Full HD video while driving and at the same time records what is happening inside the car at 480P resolution. With its IR night vision the cabin camera captures crisp details day and night. The cabin facing camera will provide additional security solution for recording videos for taxi or shared ride drivers. Loop Recording automatically overwrites the earliest file and 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 and 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 and playing the content in compatible device or playback on the 3" LCD screen.
