1.1 System Overview
Eagle Eye Direct is a system that allows you to use Versus Technology’s Active Radio Frequency
(RF) Identification tags and Versus Technology’s Infrared (IR) locator tags for real-time asset
identification, location, tracking and control. Removal of assets such as laptop computers can be
monitored as they leave a room or facility. The system transfers information using battery-powered
infrared (IR), radio frequency (RF) or a combination of IR and RF tags to transmit information to
infrared (IR) or radio frequency (RF) readers.
The Eagle Eye Direct Controller Board allows you to use Versus Technology’s tags directly with your
access control system through Wiegand reader ports on the access control panel. A tag ID is received
by the reader and sent to the controller board. The controller board converts this data to 2601
Wiegand data format and passes it to the access control panel.
Infrared (IR) Signals
The use of an IR signal has advantages for real-time tracking, since it allows accurate localization
using signals that will not penetrate walls or floors. An IR reader, strategically placed, receives IR
signals from active IR tags and provides location of assets or personnel.
Radio Frequency (RF) Signals
The use of an RF signal has advantages for asset tracking and control, since it allows assets to be
tracked even when placed inside a briefcase or other nonmetallic containers. RF signals can penetrate
walls and floors.
1.2 Terms and Definitions
The following terms will be used throughout this hardware installation guide, to refer to system
components and modes of operation.
Field-of-View
– This term refers to the infrared detection pattern or area as seen by the “eyes” of the
readers.
IR Reader
– An IR reader is a device that gathers infrared light energy and converts it to an electrical
signal, which is sent over a single pair of wires to an Eagle Eye Direct Controller Board.
Plenum
– This term refers to any area that serves as a duct or passage for breathable air. Many office
buildings use the space above the suspended ceiling as a return air "plenum" for the heating and air
conditioning systems. Most laws require that any cables, which run in an air plenum, be made of
materials which will not burn, or which will not release toxic gases when burned. (Refer to local and
NFPA Safety and Fire Codes.)
RF Reader
– An RF reader is a device that receives an RF signal and converts it to an electrical
signal, which is sent over a single pair of wires to an Eagle Eye Direct Controller Board.
Shielded Wire
– This type of wire is wrapped in a braided or foil shield that protects it from electrical
interference. Versus Technology recommends the use of shielded wire. It may be the only solution in
a very high noise environment.
