Physical security refers to the physical and electronic measures designed to monitor people and objects, and control access and intrusion to property and information. Physical security services are the services that aid and facilitate physical security measures. Physical security systems are powerful tools to prevent and investigate crimes when installed in public places such as multiplexes, shopping malls, automated teller machines (ATMs), airports, banks, casinos, and others. Rising incidences of terrorism and concerns about safety and security are some important reasons driving the demand for physical security systems, globally. With the increasing demand for physical security products due to increased criminal activities, security solutions have become more sophisticated and complicated. This has led to the emergence of services industry in physical security.
