Eufy Motion Sensor White

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° radius and up to 30 feet away—more than enough to secure an entire room of your home. 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. Requires HomeBase
