What's the door & window sensor?

Door & window sensor is an intelligent hardware with a built-in wireless WiFi module and a high-sensitivity magnetic fuse that can reflect door close/open status. Upon door/window was opened, it will trigger to generate an event and push to cloud platform by connected WiFi network.


Home security systems are comprised of a few different devices that all work together to form a layers of protection in around your home. Door and window sensors make up the backbone of any home security system and monitor which doors and windows are opened and closed. Door security devices and window security devices are often very similar. Most systems come with a set number of sensors, and then you can add more depending on how many your home might need. Ideally, the sensors get placed on every door and window in the home. If a door or window gets opened or breached when the alarm is on, the sensor sends a signal to the main control panel and immediately triggers the main alarm. There are a few different types of sensors. However, it is important to understand how your sensors work in order to keep them well-maintained.

How do they work?

Door and window sensors generally come in two separate pieces. One piece fits onto the door or window itself, while its counterpart attaches to the frame or the pane of the window. iRMTEK's home security devices do not require any additional tools for installation. Depending on your preference, heavy adhesive will usually keep the sensors in their place. If you want, sensors can be screwed directly into the frame or around the window for extra support, although it is not necessary. Position the two pieces of the sensor right next to each other, because they interact when a door or window is moved. The sensors utilize magnetic fields in order to track movement between the door or window and the frame. When they separate, such as when the door or window is opened, the sensors send a signal to the alarm panel. The panel will then assess the situation and notify you via APP for unusual activity inside your home.
