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. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings wherein like reference numerals designate corresponding parts throughout the several views, FIGS.
1-18 illustrate an Assets Locating, Tracking and Surveillance System (ALTSS), hereinafter referred to as "ALTSS" or "the system", according to the present invention, generally designated 20.
Referring to FIG.
1, ALTSS 20 for identifying, locating, tracking, and providing surveillance over physical evidence (also referred to as objects) 22 and people (also referred to as users) 24, is illustrated as being installed in an exemplary facility 101.
Facility 101 maybe divided into sectors in accordance with the radio frequency coverage (footprint) of antennas 102, which are located in the ceiling (not shown) thereof.
Other antennas, similar to antenna 102, may be positioned in the ceiling as needed to cover remaining sectors of facility 101.
Those skilled in the art will appreciate in view of this disclosure that additional antennas (not shown) may be placed at various strategic locations, such as on top of furniture, at wall and/or ceiling corners etc.
, without departing from the scope of this invention.
Antennas 102 may be connected to scanners 103.
In an exemplary embodiment, the read range of antennas 102 and scanners 103 from the ceiling downward may be approximately 18 feet.
A transponder 104 (being attached to an object) or 105 (being attached to a person) entering the field of view of a ceiling antenna 102 may be detected by scanner 103.
One or more additional antennas 106 may cover the entrance and exit 112 of facility 101.
In the exemplary embodiment of FIG.
1, antennas 106 may be configured to provide a read range of less than four feet, or the width of entrance 112.
Accordingly, a transponder 104 or 105 entering the field of view of antennas 106 is detected by scanner 103.
Any movement by transponder 104 or 105 about facility 101 may be thereby detected and recorded by ALTSS 20.
