Door & Window Sensor is an all-in-one security device designed to monitor doors, windows, and other openings. These sensors can trigger predefined scenarios when these entry points are opened or closed. For instance, if you're away from home and someone opens a door, this sensor can activate the siren system, prompt security cameras to record and transmit area footage, and notify you. It can also turn on lights inside and outside the premises, deterring potential intruders.
