This automatic door open and close detector attaches to doors or windows to sense when they are opened or closed, then reports the event to your alarm panel via a 433 MHz wireless link. It must work with an alarm panel to function—it cannot operate on its own. The sensor uses an encoder IC with 433 MHz communication to ensure reliable pairing with your compatible panel. When an entry point is triggered, the alarm panel can sound a loud alert and push notifications to your mobile device over WiFi or a cellular connection, helping you stay informed whether you’re at home or away. Install it on every door and window to safeguard every corner of your home.\u003c\/p\u003e\n\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eThe door sensor transmits the state change (open or closed) to the alarm panel using 433MHz wireless radio frequency.
