Proximity Sensors

  • When are your animals in each other’s vicinity? For how long? And how often?

    Conduct your interaction studies with our two-collar Proximity Sensor system, in which the Master collars sense the presence or absence of the SUB (‘Slave UHF Beacon’) collars. In this way, new animal interaction dynamics are revealed. This system is a cost-effective alternative for studying groups of any size.

    Proximity Sensor system
  • A two-part system

    Master Collar
    Detects the presence or absence of SUB collars and relays this information to you remotely.Master Collar

    • IridiumTrackM (800 g – 1.2 kg)
    • WildCell GSM (500 g – 950 g)
    • Schedules may be altered remotely
    • Video camera option

    SUB Collar
    When the SUBs are within short range of the GPS Master, the SUB IDs are recorded by the Master collar.SUB Collar
