Pair the Radar Module with the U1000/X1000/Q1000 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/X1000/Q1000 does not save the footage and resumes Energy Saving Mode 2.0.
