Smart Alarm System with 100DB Siren — Smart Home Security Set Compatible with Motion Detectors & Door/Window Sensors

Keep track of door and window activity in real time via the companion app. Each sensor records open/close events, and when multiple door/window sensors are placed around your home their current states are shown simultaneously for a quick overview. Low-battery push notifications are sent to your smartphone to remind you to replace batteries. Setup is DIY-friendly: power the device, open the app and add the unit to complete installation. The security set features a 100DB siren for loud alerts and works with motion detectors as well as door and window sensors, allowing you to create tailored security scenarios.
