Or a shock sensor might activate because of an earthquake. There have been cases where shock sensors activate because of someone knocking hard on a door or by tapping against a window. But breaking a door or window without activating a shock sensor is next to impossible.Īn important thing to remember about shock sensors is that they can be overly sensitive, and they may activate during non-emergencies as well. If an intruder is careful, they may be able to do this without activating a door and window contact. An intruder may break a window or break down a door when entering a property. The application of shock sensors for alarm systems is somewhat obvious. Shock sensors can be hardwired, or they can communicate with the alarm control panel wirelessly. The shock sensor will then know to alert the system. The force behind a powerful shock wave can be detected by a shock sensor and cause it to activate. It refers to a wave of energy that moves faster than the local speed of sound. The term "shock wave" actually comes from physics. This will tell the shock sensor to send an alert to the alarm system to let it know about the situation. When a large shock wave is detected, the shock sensor will activate. A shock sensor works by detecting the shockwaves that are associated with a window or a door being broken.
