How does dual motion detection of the Video Doorbell Dual (battery) work?
PIR (Passive Infrared) sensor can sense objects with heat and infrared rays, and radar can detect the movement of objects through sound waves.
In user scenarios, if a car passes by a distance of 15 meters from the front door, due to the high heat, PIR will also be triggered to issue false alarms；
Through dual motion detection technology, users can be flexible when setting the detection range in front of the door, including angle and distance. When the PIR sensor is triggered, the radar will scan the detection range. If no moving object is found, the doorbell will not notify the user.
