What is the Geo Vehicle Detector?          


  1) It detects passing vehicles through comparing different of earth geomagnetic field by Geo 

     Vehicle Detector which is installed on a wall of pathway without loop coil.

  2) When it detects a vehicle, it outputs to run a warning signal, and can be set up to 50 seconds 

     by inside timer function.


  3) Also it provides compatible functions with loop detectors through having a presence output 

     without timer function and pulse output.

  4) Geo Vehicle Detector only detect vehicles or metals without loop coil except pedestrians 

     therefore it gives convenient maintenance and cost saving against existing loop detector.







[ Requires the length of the Sensor Cable ]





Non loop coil Vehicle Detector (Complete assembled / single channel)              


  1) Geo Vehicle Detector with Sensor Module including housing, adapter and terminal.


  2) Same specifications as Geo Vehicle Detector(GVD-3S)

  3) Height for bottom of housing : 50cm(1.64ft) from road

  4) dimension : 280 x 280 x 130mm

  5) Material of housing : Plastic with waterproof (IP66) 



Installation Tips                                   


  1) Do not install the Sensor Module at around (about 1 meters) any motors such as Barrier 

     Gate, fan of Air-conditioner, etc.


  2) It can be installed at 50cm(1.64ft) height between bottom of housing and road.

  3) It's required to install the sensor module which is faced the round side with passing vehicles..

  4) When it turns on power of the detector, the Green LED light is turns on for an initialization 

     about 10 or 20 seconds but it can be exceeded when the Geomagnetic field is not stable.



  5) When the Geomagnetic field is not stable, the initialization will be extended and need to press 

     the reset button to restart the initialization.

  6) While initialization please don't approach any metals or vehicles to the Sensor Module.
