2.3.2.2 Radio Frequency (RF) Sensor (VER-4452)
RF Sensors operate at 433.92 MHz receive frequency. They convert
encoded RF signals emitted by badges into electrical signals, and send them
to Collectors via a single unshielded, twisted-pair wire.
Planning the location of RF Sensors depends upon the facility. In most
cases, for complete coverage, they can be placed approximately 100’ apart, because they have a
sensitivity range radius of approximately 50’. However, because concrete and steel structures
absorb the RF signal, and other materials affect the strength of RF signals, testing is necessary to
determine the best placement of RF Sensors.
2.3.2.3 Supervised Sensor (VER-4442)
The Supervised Sensor is an IR Sensor with the added ability to generate its
own badge signal, allowing the Versus system to monitor the data delivery
to its Collector. Using one Supervised Sensor per Collector, the Versus system can send an alert if
a portion of the sensory network or facility intranet stops sending badge data. Utilization of this
Sensor’s supervisory capabilities requires the use of the Collector Checker software (included with
the VER-8000 Data Server software) and Audio/Visual Services software (sold separately). The
Supervised Sensor contains a red diagnostic LED that flashes when receiving IR signals, or stays
lit when the Sensor is flooded by light.
2.3.2.4 PC Sensor (VER-4444)
The PC Sensor is an IR Sensor that can be attached to any PC computer to
create a location zone. Unlike a standard IR Sensor, no hardwiring is
necessary. Simply attach it to a computer’s serial port, install the software,
and you have a permanent or temporary location for use with the Versus
Information System. The PC Sensor’s range is 4-6 feet in front of the Sensor,
and the computer to which it is attached must be running in order for it to sense badges. To
accomplish a greater sensing range, a standard IR Sensor may be wired to the PC Sensor to be
used externally. An RF Sensor may also be wired to the PC Sensor.
2.3.3 Collectors
After Sensors receive signals from badges and convert them to electrical
signals, the data is passed to a Collector. The Collector accepts the inputs
from the Sensors and assembles the inputs into larger, network-ready
packets. The packets are then relayed to the Ethernet Concentrators.
Note: Although all Versus Collectors can support up to 24 Sensors, we recommend placing no
more than 20-22 on each Collector at initial installation to allow for future expansion without
having to add additional Collectors.
