T8910021 Eufy 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° radius and up to 30 feet away—more than enough to secure an entire room of your home. 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.
