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.

Door and Window Sensors


Protect America‘s door and window sensors are surprisingly simple. They create a magnetic field that, when broken, sends a signal to your central Simon XT control panel and sounds the alarm. Protect America only uses wireless sensors that can be used on either doors or windows, allowing for greater system customization. For most homes we recommend one sensor for every accessible door and window. Door and window sensors are the most common piece of security equipment when it comes to securing your home. Protect America uses wireless micro sensors to help keep them inconspicuous and out of the way. We recommend a door or window sensor to be placed on any easily accessible door or window to attain a secure home perimeter.

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. Protect America’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 of unusual activity inside your home. In the event of a burglary, your professionally monitored home security system will contact the emergency response center closest to you in order to dispatch help.

    Your Home Starts at the Front Door

    Did you know your door and window sensors can also be used to secure areas of your home that you want to keep private or off-limits? For example, if you have a liquor cabinet that you want to secure from curious children, or an office you want isolated, simply place the sensors in the entry way of these areas in order to keep tabs on when they are opened. Programmable deadbolt locks are also recommended for doors around the home, especially the front door.
