Burglar alarms
Piezoceramic transmitters find a variety of applications in burglar alarm systems. For room protection, ultrasonic motion sensors in which a piezoceramic transmitter sends out ultrasonic pulses and then picks up the reflected waves again are used. Every entry into the room as well as every movement within the room is detected.
For the protection of property, small sensor plates mounted on the property concerned (e.g. on the shop windowpane) are used. These sensors pick up the structure-borne noise and transform it into electrical signals. Sounds and vibrations caused by the intruder's tools are enough to set off the alarm at the very beginning of the break-in attempt.
These kind of sensors are as well used in modern cash maschines of credit institutes.
