Home Security 101 – What is a Door/Window Sensor?

Every monitored home alarm system starts with the wireless door/window sensor. Your basic Smart/Safe Home package contains three of them. The technology goes back almost a hundred years, and over a hundred million of these devices are in use, with over a million more installed every year, just in US homes. There’s an excellent reason why this device is the core of any good alarm system: intruders invariably try to enter through a door first. Burglary entry stats look like this:

  • 34% of burglars enter through the front door
  • 26% enter through a back or basement door
  • 9% enter through the garage

That’s almost three quarters of all burglaries starting with a door – now you see why the layout of every good home alarm system starts with exterior doors  The intruder wants an easy entry- and a fast and easy exit, ideally with an armload of your stuff.

How the Door/Window Sensor Works

The standard door sensor is a battery powered magnetic switch and consists of two small parts: one part mounts on the top of the door frame (on the opposite side from the hinge), and the smaller part (the magnet) is placed in close proximity on the door itself. When the door is shut, the two pieces are within a half inch of each other, and your alarm system can be armed. When the door opens, and the pieces are separated, that triggers the alarm. It’s simple, and it works like a charm. . There are even recessed door/window sensor sif you don’t want to see the sensors at all. Here are some more telling stats:

  • 12% of burglaries occur through an unlocked door.
  • 41% of burglaries in homes with alarm systems occur when the security system is not turned on.

Each home is different and you may want to add more than three to your system. Your Burns & McBride Smart Safe Home System is easy to add additional sensors to.

In addition to sending emergency notifications for break ins, these units can also be programmed to send you messages if items such as liquor cabinets are opened while you are way.
