2. System Description
The Versus Information System is a reliable, flexible platform for locating personnel and equipment.
The system badges, worn by staff or attached to assets, emit signals that contain information about the
badge. The information is sent through the sensory network to a host computer that retrieves the
information and translates the data into names of rooms, personnel, and equipment. Workstations
throughout the facility can access the location data with various client software programs, which
display current locations of personnel and equipment, display alarms on the monitor, send pager
messages, and store for later use in reports and archiving.
System Structure
2.1 Infrared (IR) Tracking
The use of IR signals for tracking has distinct advantages, since it allows accurate locating using
signals that will not penetrate walls or floors. A system of strategically placed sensors receives IR
signals as badges move between rooms of a building.
2.2 Radio Frequency (RF) Signals
In addition to the IR signal, a low-power RF signal is incorporated into some badges. RF signals
penetrate walls and ceilings, which allows the RF signal to act as a backup if the IR signal is blocked.
If the IR signal is blocked, and an RF sensor senses the RF signal, the last known location of the badge
is shown. In addition, RF badges and sensors can be used for security purposes in locations where
tracking assets is important.
