Great question @coachsay! If you arm your Ring Alarm before the Motion Detector has cleared (is still detecting motion), the Motion Detector will be armed and will not be bypassed. Ring Alarm is smart enough to know that as you exit your home you may trigger the Motion Detector, and you should not be confused with an intruder. After you leave your home and movement stops, the Motion Detector will clear as expected and be ready to detect movement. Any motion that is detected at that point will trigger the Alarm. We recommend using both Contact Sensors and Motion Detectors to create a ring of security around your home. By using Contact Sensors at every entry point around your home, any intruder would be detected and set off the Alarm after your customizable Entry Delay. I hope this helps! :)

Could you please clarify: does this item record video as a Ring doorbell does when activated? Thanks!

@Momofsdg The Motion Detector for the Ring Alarm Home Security System does not have a camera, and therefore does not record the motion, but will make a record of the event in the event history, showing as motion detected at said time and date.
