Glass break sensors are the single fastest way to be notified about an intruder.
The difference is a glass break sensor tells you the moment a break in happens where as a motion sensor triggers once the intruder is inside the home. Those valuable seconds can be the difference needed to protect your family.
Where to put your glass break sensor
On the ground level or basement
Within a 20 foot radius of the window you want to protect
Away from the walls that actually have the windows
Within a clear line of sight of the window itself
Once installed try playing a glass break sound on your phone next to your window to be sure your sensor will work properly
