When the alarm is turned on, a magnetic current connects a simple circuit, and whenever the current is disturbed, by opening or closing the door or window, the magnetic current alerts and sounds the alarm.

The homeowner is then notified remotely through the system, or by a monitoring device.

In order to make a wise decision about the right door and window sensor for your home, you need to consider the following things:

  • Decide which windows and doors you want to secure, because if they aren't accessible to someone on the ground, for instance, you might not need to protect them (or their priority to you may be considered lower risk)
  • Check if the company you are thinking of offers any kind of warranty, and has good customer service
  • Go with vented window sensors if you like the possibility to arm an open window
  • Choose a simple-to-use alarm sensor which will be convenient for every family member
  • There are basic open-close alarm sensors, and more complex ones which detect broken glass, sawing or drilling, so look for one according to your needs
  • Ask if there are secondary pass codes for relatives or other family members to turn on and off the system
