TRC 3-A Wireless Underground Intrusion
Detection System
Our inexpensive TRC-3 Seismic Movement Detection
Systems are High-Quality devices that "feel" the
ground vibrate from footsteps or vehicle movement
and alert you by radio receiver (included). Included
with the receiver are four movement detecting
sensors or "probes", each with its own separate
transmitter. Each sensor is connected to its own
transmitter by an 8 foot cable, allowing the sensor
itself to be buried or submerged. Each of the
sensors can monitor footstep vibrations in an
area 260 feet in diameter and movement of heavy
vehicles to a much greater distance. The four
monitored areas allow placement of the sensor/transmitters
as desired. Activated in seconds, even in total
darkness. Each sensor/transmitter is corrosion
resistant and ruggedlized for reliable operation
under severe circumstances.
PULSE-TONE CODING allows monitoring all transmitters
simultaneously on the same radio frequency. Similiar
to Morse Code, each transmitter emits a different
number of tones when activated, and the number
of pulses embossed on the transmitter housing
for swift sure identification by touch even in
total darkness. Transmitters have uilt-in sensitivity
controls and an on/off switch. The system can
be used with any combination of one to four transmitters.
Easy to conceal, but even if exact location is
known, sensor/transmitter cannot be approached
without transmitting a movement alarm. Sensitive
enough even to detect turbulance of helicopter
blades overhead. If the cable is severed in an
attemp to disable it, the unit will transmit continuously,
warning you
