WebA shock sensor works by detecting the shockwaves that are associated with a window or a door being broken. When a large shock wave is detected, the shock sensor will activate. This will tell the shock sensor to send an alert to the alarm system to let it know about the situation. The term "shock wave" actually comes from physics. http://www.cham.co.uk/_docs/casestudies/CHAM_Case_Study-Shock_Tube-16.01.18.pdf
