Seismic Sentinel

Supplied components; Control unit, probe, 200 ft wire with winder, connectors, dielectric sealant, 9 volt battery,  user manual

The Seismic Sentinel is a ground vibration sensor system designed for detecting personnel or vehicles.

  • It is flexible in usage, limited only by imagination.
    • Monitor a trail to your campsite and sleep with the control unit next to you. Easier to set up than trip wires.
    • With an obscured driveway, path, or field install the unit in the home and you will detect both people and vehicles approaching.
    • Be alerted if your bug out location’s perimeter is breached by dismounted intruders.
    • Probes have been deployed at distances greater than 1/2 mile from the controller to monitor pasture entrances.
    • Remote buildings can be monitored easily with a probe centered in the sensitive area, no need to wire every door with a switch.
    • Place a probe near a vehicle or machinery and be alerted before someone can come close let alone move it.
    • Into paranormal? Place a probe inside a building using our flat plate mount and watch the LED graph for seismic activity.
  • The LED bar graph indicates seismic strength when personnel or vehicles are near the probe.
    • Depending on soil type, the sensing diameter from probe is approximately 50 feet for a man walking.
    • Hundreds of feet for a vehicle on a road or driveway.
    • Probes can be paralleled for a large coverage area.
  • A user settable threshold level rotary 10 position switch determines  when an alert tone is sounded.
    • This unique feature easily reduces false trips.
    • The user selects at which seismic activity level, shown on the LED bar graph, that will sound the alert tone.
    • Each of the 9 switch positions matches an LED bar of the display to make setting the trip threshold simple.
    • The 10th position turns off the alert tone for silent operation but the LED graph continues updating.
    • The first LED usually flickers showing the background seismic activity thus an indication of working.
  • It can be portable or permanent  because of its small rugged design and low battery power requirements.
    • Operates over 2 weeks on one standard 9 volt battery which is included.
    • It can be powered from 2 to 30 volts DC which can be provided by vehicles or a solar panel.
    • The 2 conductor com wire is furnished on a handy winder which makes deployment and take up hassle free.
    • Almost any type of wire can be used for the connection from the probe to the control unit.
  • It is instantaneous and continuous  updating the LED bar graph indicator in real time.
    • Foot steps are easy to recognize as varying amplitude of LEDs on the bar graph.
    • The Seismic Sentinel can repeat the alert on every occurrence of a footstep if need be.
  • It is stealthy and easy to conceal and hide the probe and wire.
    • Because the probe and wire is buried thus hidden, intruders never know they have been detected. 
    • Probe is water tight and is designed to be buried just below ground level.
    • Forget using trip wires, infrared, or light beams which can be avoided.
  • Industrial grade components are used throughout the construction.
    • Housed in a machined cast box not a bent aluminum or plastic enclosure.
    • Optional Pelican case is available that makes keeping the control unit, probe(s) and any small items together easy.

 

  • State of the art electronic design.
    • 6 month warranty on control unit, 3 months for probe.
