2.3.2.1 Infrared (IR) Sensor (VER-4426)
IR Sensors receive IR signals from badges and convert them into electrical signals. A single
unshielded twisted-pair wire transmits the signals to a Collector and provides the Sensor’s
operating power.
The VER-4426 Hi-Efficiency IR Sensor replaces the original VER-4422 IR Sensor.
The new version is less susceptible to interference from outside IR and RF noise and
fluorescent lighting. They also read low battery badges at greater distances. The Hi-
Efficiency IR Sensor can be identified by its dim yellow Activity Indicator Light that
blinks when an IR signal is received, and stays on when the Sensor is flooded by
outside interference—a feature which can be a helpful troubleshooting tool.
The maximum run length from an IR Sensor to a Collector is 1000 feet. IR Sensors have 360-
degree horizontal coverage, 180-degree vertical coverage, and 15-foot reception distance.
An additional focus ring can be installed inside the IR Sensor to narrow its pickup range to a
smaller area, which can be useful in rooms with multiple patient beds or for pinpoint desk-to-desk
coverage in a nurses’ station.
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 VIS to monitor the data delivery to its
Collector. Using one Supervised Sensor per Collector, the VIS 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 VIS. 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,
