ANKER eufy Security by Smart Battery Powered 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. Link it Up: Connects to eufy Security HomeBase (Not Included) and well as all other eufy Security products. Simply pair it via the eufy Security app and press the button on the sensor to add it to your system.
