Common motion sensor alarm systems work by using the following technologies: 1. Passive infrared motion alarm sensors detect body temperature of the moving objects. When the access control system is in armed mode, it can sense skin temperature and body radiation that differs from the inanimate objects in the background.

An animal confinement arrangement including a home base for transmitting a modulated signal and a receiver for receiving the modulated signal. The received modulated signal is demodulated using a demodulator. The demodulated signal is compared to a reference signal to produce a comparator signal indicating if the received modulated signal was transmitted by the home base.

A security alarm is a system designed to detect intrusion – unauthorized entry – into a building or other area. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary or property damage, as well as personal protection against intruders.Security alarms in residential areas show a correlation with decreased theft.
