The sensors are connected to the device of alarm, and then in the case of violation of the integrity of designated sites (breaking and opening doors, breaking windows), alarm switches on to alert security about the danger posed to the object.

Infrared alarm sensors;
Radio wave motion alarm sensors;
Vibration alarm sensors;
Capacitive sensors alarm;
Magnetic (reed) sensors to open doors and windows;
Ray alarm detectors;
Acoustic sensors of glass break;
Shock sensor etc.
Most alarm sensors are responsible for detecting and locating places of unauthorized entry, and the base unit (control panel, which collects all the information from sensors) provides a response in the form of the inclusion of sound and alert the owner and security agencies.
