safety alarm sensor system for doors and windows in your homeThe absolute front line of defense in a home security system is secured doors and windows. Of the more than two million home burglaries reported each year, nearly 66 percent are residential break-ins. What is the most common entry among thieves? Doors and windows, often unsecured. Protecting them is a definite priority when it comes to securing your home. In addition to a reliable lock system, door and window sensors are an essential part of any basic home security system package, preventing entry and potential danger to your home and family.

How Do Door and Window Alarm Sensors Work?

Doors, windows, cabinets and drawers— anything that opens and closes—can be protected using a door and window sensor. Wired or wireless, they are easily installed into a house that is being built or an existing home. Wired sensors tend to be less expensive, but wireless sensors are more easily moved.

Door and window safety sensors work with a sensor and a magnet. The sensor is installed on the window or door frame and the magnet is attached to the window or door itself. When the alarm is armed, a simple circuit is connected by a magnetic current that sends a message to the alarm when the current is disturbed. Opening or closing the door or window disturbs the current, the alarm is sounded, and the homeowner is contacted remotely through the system or by a monitoring service.

There are several types of window and door sensors available:

  • Surface contact sensors and magnets are installed onto the surface of the door/window frame and the door/window. The least expensive option, but also the most noticeable.
  • Recessed contact sensors and magnets install inside the frames and inside the door or window, making them less visible.
  • Vanishing sensors are very thin and virtually undetectable, blending into any décor, and hidden from the eyes of intruders.
  • Vented window sensors use two magnets so an armed window may remain open a few inches—any further and the alarm is triggered.
  • Garage door contact sensors are installed onto or into the garage floor and the magnet affixes to the door, even rolling doors.

Features/How to Choose a Door and Window Sensor for Your Home

Including door and window sensors in your home’s security system makes good sense. There’s a reason this feature is the most popular device in home security—it’s the first step toward preventing home intrusion. But, as with any security feature, every household is different and families need to determine their unique needs to ensure optimal protection from door and window sensors.

The following may be helpful in making the best choice:

  • Determine which doors and windows you want protected.  If they are not accessible, they may not need to be armed.
  • If you want the ability to arm an open window, be sure you opt for vented window sensors.
  • Does the company you’re considering offer maintenance and repair service?
  • Is the alarm simple enough for every household member to use?
  • Are there secondary pass codes for family members or relatives to arm and disarm the system?
  • Do you want a safety sensor that also can detect broken glass, drilling or sawing that may be missed by basic open-close sensors?
