An object locating, identifying, tracking, and surveillance system, denoted the Assets Locating, Tracking, and Surveillance System (ALTSS), is provided for managing physical objects and evidence in environments such as police departments, law offices, and the Courts. ALTSS employs radio frequency identification (RFID) technology, computer programming and database applications, networking technologies, and hardware elements. ALTSS may locate and track physical evidence, merchandise, information carriers like files, folders or individual pieces of paper, and people, under certain conditions, in near-real time. It may be configured as part of a local area network, a wide area network, or the Internet. ALTSS may employ exemplary components such as RFID transponders, scanners, strategically located antennas and computers to facilitate tracking of objects and people as needed. Any number of users having access privileges and connected to the network may access ALTSS directly or remotely via the Internet to locate and track evidence or objects. |
