Did you know that 34% <\/strong>of burglars enter through the front gate and 23% <\/strong>break in through a first-floor window? Yet, businesses with security systems with door and window alarms\u2014are less likely to be targeted.<\/p>\n\n\n\n

With numbers like these, it\u2019s clear that a simple sensor alarm can make a big difference. But what exactly are door and window sensor alarms, and how do they work?<\/p>\n\n\n\n

Door and window sensor alarms are small devices that alert you when a door or window is opened. They act as your first line of defense against intruders.<\/p>\n\n\n\n

But how do they detect movement? Are they worth the investment? What features should you look for? And are they enough to protect your businesses?<\/p>\n\n\n\n

In this blog, we\u2019ll cover everything you need to know plus a groundbreaking security solution making waves among businesses across North America.<\/p>\n\n\n\n

What are door and window sensor alarms?<\/h2>\n\n\n\n

Door and window sensor alarms<\/strong> are easy and affordable security devices that use a sensor and magnet.<\/p>\n\n\n\n

In all cases, installers place the magnet on the moving part of the door or window and mount the sensor on the stationary frame.<\/p>\n\n\n\n

How do they detect movement?<\/strong><\/h3>\n\n\n\n

The magnet keeps the circuit intact when the door or window closes. Opening the door or window breaks the circuit and triggers the alarm.<\/p>\n\n\n\n

There are different types of magnetic contacts<\/strong>, based on where they are placed on the door or window:<\/p>\n\n\n\n

Surface mount magnetic contacts:<\/strong><\/h4>\n\n\n\n
\"Magnetic

<\/p>\n\n\n\n

These are installed on the surface of a door <\/strong>or window frame and the moving part (door\/window). They are visible and easy to install but might be more exposed to tampering.<\/p>\n\n\n\n

Recessed magnetic contacts:<\/strong><\/h4>\n\n\n\n

Installers place these inside the door or window frame, making them more discreet and harder to detect or tamper with. Installers place the sensor and magnet inside the frame and align the magnet with the sensor when the door or window is closed.<\/p>\n\n\n\n

Manufacturers specifically design these for overhead doors, often found in garages or warehouses. Installers mount them on the top of the door and frame.<\/p>\n\n\n\n
