What Is A Window Sensor?

Window sensors detect and report the opening and closing of windows and doors.

The features of a window sensor make it perfect for home care, smart lighting, network management, and home security applications.

As part of a home security system, a window sensor can be used to alert the homeowner or security company if a window is opened when it shouldn’t be. This can help deter burglars and other intruders from entering the home.

How Do Window Sensors Work?

Window sensors typically use magnets to detect when a window is opened. The sensor is usually mounted on the window frame, and the magnet is placed on the window itself. 

When the window is closed, the magnet creates a magnetic field that triggers the sensor.

When the window is opened, the magnet is moved away from the sensor, causing the sensor to trigger an alarm.

Since window sensors are wireless, they connect to the home security system using radio frequency (RF) waves.

This allows the sensors to be placed anywhere in the home without wiring.

What Are The Benefits Of A Window Sensor?

Now that you know how a window sensor works, let’s discuss some of the benefits of using one.

1. Keeps Out Criminals

When you set up and enable window and door sensors, your home security system will alert you whenever the sensors are triggered.

In addition, if your home security system has a monitoring feature, the service provider will be alerted anytime the sensors are activated. They will be able to contact authorities and call you to assure you are safe.

2. Additional Deterrent

If your home security system is triggered and someone tries to force their way in through the windows, a loud alarm sounds.

This will not only deter burglars who do not want to draw attention to themselves, but it will also notify you and your family that a break-in attempt is underway.

3. Peace of Mind

Window sensors can provide peace of mind, knowing that your home is more secure.

Not only will you be alerted if someone tries to break in, but you’ll also know that your doors & windows are closed and locked when they should be.

With the number of home invasions rising yearly, these sensors are an important addition to any home security system.
