Smart Motion Door Sensor - Wireless Home Security System, PIR Motion Detector Alert, Add Hub to Make it Compatible with Alexa

[Motion Sensor Detects Your Movements] With a motion detection range of up to nearly 30 feet within 110° horizontally and 55° vertically, there is ample coverage to secure an entire room in your home. You can also adjust the sensitivity settings so that you are only notified about movements that are important to you. With the built-in light sensor, it will automatically activate the button pusher to turn on the light if someone moves when the surroundings become dark. [Part of Ecosystem & Compatible with Alexa] Link the Motion Sensor with other products and configure a Scene in the app.

When you arrive home, the button pusher will automatically be activated to turn on the light, and Alexa will say "welcome home". When you depart, the Indoor Camera will automatically activate to monitor indoor activity while you are away (Hub required). [Remote Alert Notification] You will get an alert if a suspicious person enters the house while you are away. (Hub required) [Energy & Money Saving] By detecting the room is empty, the Motion Sensor automatically switches off the lights, cutting down on unnecessary energy use
