Your home’s entrance points, be it a door, French window or regular window is the weakest point in your security plan. An unsecured door is like rolling out a “red carpet” to a burglar. This is why door sensors are one of the most popular home security devices on the market today.

In fact, the very first electronic home security system invented way back in 1853, relied solely on these sensors. It had a pair of electromagnets attached to the door, which rang a bell when someone opened a door or window.

The modern “door sensor” has come a long way since then. Here’s all that you need to know about these gadgets – the working, how to use it, types and frequently asked questions – you’ve got all that you need right here.

How Does Door Sensors Work?

Nearly all door sensors in the market today make use of a “reed switch” to determine when a security breach occurs. Each sensor has one reed switch and a magnet to create a closed circuit. When someone opens the secured door or window, the magnet moves away from the switch, breaking the circuit.

This, in turn, triggers a predefined event. It can be anything from sounding an alarm, alerting the local police or sending a text message to your Smartphone. You can set up any trigger depending on your requirements.

While most door alarm sensors work using this underlying principle, there are plenty of ways you can configure them based on your specific requirements.

You can configure the system to ring a bell inside the house when someone attempts to open an exterior door or window. This is highly useful when you’re at home. For those instances when you’re away, you can configure it to send a detailed event report as a text message to your phone or alert a central monitoring station. Additionally, some latest devices on the market come with an inbuilt camera that captures an image of the intruder and sends it to your Smartphone.

The two major types of door sensors include Wired and Wireless. In a wired sensor, the device is connected to a power supply. A wireless door sensor, on the other hand, has a battery that powers it.

Here are some common FAQs about Door and Window Sensors:

  • Will the system trigger an alarm if I leave a window slightly open for ventilation while I’m away?

No. You can set the sensor at various safe positions like “fully closed” or “open 5 inches” and so on. This way the alarm sounds only when the window moves away from these positions.

  • My door/window isn’t of the regular shape or material. Will I be able to use a door sensor?
