Abstract

A security system for locating items of electrical equipment, which is comprised of security identification units and a controller unit, the security identification units being located within the items of electrical equipment. To provide power to the items of electrical equipment they must be connected to a power distribution network, which may be a national electrical grid or 'mains' supply. In use the security identification units are arranged to communicate identification data with the controller unit via the electrical power distribution network, thereby providing an indication of a presence or an absence of at least one of the items of electrical equipment.
