Door and window sensors are must-have security solutions for businesses. Burglaries are an unfortunate event that businesses need to protect against in order to prevent some sort of financial loss should one occur.

What Are Door And Window Sensor Alarms?

They are devices that are installed on doors and windows to detect the presence of intruders. If a thief is attempting to open a door or a window on your property, these sensors can trigger a siren, a flashlight, a phone call, or a combination of these.

Door and window sensor alarms consist of 2 components – one attaches to the door or window itself while the other attaches to the frame. The 2 components should be placed next to each other so that when the door or window is forcefully opened, they can send a signal to trigger the alarm.

There are various types of door and window alarms. Surface contact sensors and vented window sensors use magnets to detect the motion of doors and windows. Recessed contact sensors and vanishing sensors are barely visible.

Additionally, door sensor alarms can be classified into two categories, namely door-open alarms and door-forced-open alarms. Door-open alarms activate when the intruder opens and holds the door for a specific amount of time.

Door-forced-open alarms are triggered when the intruder opens the door forcefully. For example, if the door requires an access card and the thief tries to use physical strength to open it, the alarm will trigger.

What Are The Benefits Of Using Door And Window Sensor Alarms?

Collect insights

Aside from being connected to an alarm system, door and window sensors can provide real-time data on accesses and space utilization. You can for instance know if a door is left open by an employee, or if all doors are night are closed and locked.

Preventing thefts

Door and window sensor alarms help to improve the security at your office. When an intruder tries to open the doors or windows of your building, the alarm will be activated. The loud noise generated from the alarm can cause the thief to panic and not proceed further into your building.

Achieving peace of mind

These sensors help you to have peace of mind at night, on weekends, or if you are traveling abroad. When an alarm is activated, you or the security company will receive a notification. Then you can ensure that proper security measures will be taken in case of a burglary.
