To deter an intruder from trying to prise open a window, you can fit a contact alarm that will emit an alert when force is used to break in via a window.
However, an alarm like this can’t detect the difference between a window being opened rather than being forced. Instead, glass break sensors can be used to raise the alarm at the sound of breaking glass.
For ultimate window protection, you can use contact alarms and sensors together.
Burglaries are often opportunistic. An open window or a window which is clearly in disrepair will be like candy to a baby, so we highly recommend you give your windows and frames a health check each year to ensure they are giving you and your family the security and protection you need.
