SYNC ALARM ACCESSORY: The Pet PIR Motion Detector is easy to pair with your Yale Sync Smart Home Alarm through the Yale Alarm App. PET FRIENDLY DETECTION: These Pet PIRs don't detect motion below 25kg, so you can be rest assured if your furry friends are left home with your alarm armed, they won't set it off. TAMPER PROOF MOTION DETECTION: Triggers your alarm and notifies you immediately when motion is detected within the large, 12 metre, 110 degree range. INSTANT NOTIFICATIONS: Get notifications to your Yale Alarm app if movement is detected in your home while the alarm is armed. EASY TO SET UP & INSTALL: Link to your Yale Sync Smart Home Alarm straight out of the box. Completely wire-free, with no need for cables running through your home. You can attach to any surface, either via a screw or sticky-back for greater convenience.
