Eufy Security Home Alarm System Motion Sensor

Protection That Lasts: The included battery provides up to 2 years of power for round-the-clock security. Extensive Coverage: Detects motion within a 100° field of view up to 30 feet away—more than enough to secure an entire room of your home. (NOTE: This motion sensor is not waterproof.) Adjustable Sensitivity: Tailor the sensitivity of the motion sensor so that it only alerts when humans are in range—rather than your playful pet dog or cat. App Alerts: Notifies you as soon as motion is detected, sending a message to your phone via the eufy Security app, no matter where you are. Optional 24/7 Protection Service: New optional 24/7 professional monitoring service is now available for 24/7 emergency police, fire and medical response when your alarm system is triggered.
