Pair the Radar Module with the U1000/X1000/Q1000 Dash Cams to extend its parking surveillance duration while reducing power consumption when set to Energy Saving Mode 2.0. The Radar will detect motion and allow the dash cam to prepare to save an event clip. If an impact is detected, a 20 second video (10 seconds before and 10 seconds after the impact) is saved in a dedicated folder on the MicroSD card. When no impacts are detected, the U1000 does not save the footage and resumes Energy Saving Mode 2.0. *Parking Surveillance mode requires Hardwiring Cable and installation (professional installation recommended).
