Abstract

Security alert apparatus comprises a receiver unit 11, and one or more transmitter units. Each transmitter unit is programmed to emit signals in 20-30 msec bursts at 3-4 second intervals, the signals being 20-bit or greater randomly generated pseudo-unique identification codes. The receiver unit is initialised to learn the codes, and then compares codes contained in signal bursts with learned and stored codes.
If any learned code is not detected within a prescribed period (greater than the burst repeat interval) an alarm is generated. The transmitter units may be fixed to articles of property or to children to guard against mislaying, theft, straying, or abduction.
