Buffered Parking Mode

Parking Mode Solution

Not only capture the aftermath, but also record events leading up to an impact. When an event is detected, it saves 15 seconds video before the event and 30 seconds after the event.

(We recommend to buy VIOFO HK3 Hardwire Kit. With ACC detection, the dash cam will switch to parking mode automatically if the vehicle engine is shut off,and switch into normal recording when the vehicle engine is on.)

Automatically record when detecting moving objects or impact while car is parking.

A video is recorded at a rate of low fps, compressed into a long file.

Record video at low bitrate to save storage space.
