Door & Window Sensors: How They Work

When it comes to home security, it is undeniable that door and window sensors are the backbone of the system. When you purchase a home security system for your house, you will receive a set number of sensors at your disposal. The number of sensors could also be increased for an additional fee. Most people opt to place the sensors at the lower part of their homes because it is cheaper to do so. However, if you want to experience maximum security for your house, you should place the sensors at every door and window. When the door or the window is breached while the alarm system is operational, the untimely opening of the door or window would ultimately send a signal to the main system and trigger an alarm.

If you are wondering how door and window sensors work, then here is a simple explanation. The sensors would come in two pieces. The first one would fit the window or the door itself while the second would be attached to the frame. You can either screw the sensors in place or use a strong adhesive. These two pieces interact with each that is why it is important that you position them right next to each other. Once the two pieces are separated, they will send a signal to the main control panel to trigger the alarm.

These sensors could be directly wired into the system. But there are also those that make use of batteries to power them. The differences between the two is that the wired ones would take more time and effort to install while the battery powered ones would need regular checking.

To make the connection between the two pieces, some sensors would use magnets. The magnetic fields make the connection and when the field is broken, the alarm goes off. Some sensors use a light beam to connect the two pieces and when it is breached, the alarm is activated.

Regardless of type, sensors play an active role in the security of your home. When there is a break-in at your home, these 1st response alarms can help notify you immediately.
