HaViMo-ST

HaViMo-ST™ is a visual traffic flow measurement sensor. Using HaViSys OTFIP™ technology, the result is computed on board. Several extensions are provided to integrate the data into the System. Device configuration is possible either locally or remotely, when integrated into HaViSys-Cloud™ service.

Extensions

  • Optical
    • WIDE_EXT
      • Wide angle adapter: Increase the view angle of the camera with a factor of 2x. Useful for wide Highways or when the sensor can not be installed high enough.
    • TELE_EXT
      • Tele adapter: Zoom in with a factor of 2x. Useful for measuring far targets.
  •  Electrical
    • HAVIMO-2-LAN
      • HaViMo adapter to Ethernet: Allows TCP/UDP connection to the device. MODBUS-TCP connection is supported on this adapter. Can also be used for connecting to HaViMo-Cloud™ service if internet connection is available. 
    • HAVIMO-2-WLAN
      • HaViMo adapter to wireless LAN: Allows TCP/UDP connection to the device. MODBUS-TCP connection is supported on this adapter. Can also be used for connecting to HaViMo-Cloud™ service if internet connection is available. 
    • HAVIMO-2-RS485
      • Adds RS485 Physical Layer to HaViMo hardware. This allows differential data communication over long distances. Used for local configuration of the device.  
    • HaViMo-2-GPRS
      • Connects HaViMo devices to HaViMo-Cloud™ service over GPRS. A SIM card with enabled data plan is required by the adapter to function properly.
    • HaViMo-2-3G
      • Connects HaViMo devices to HaViMo-Cloud™ service over GPRS. A SIM card with enabled data plan is required by the adapter to function properly.
    • HaViMo-OUT
      • Adds 4 digital trigger outputs to the device. It can be used to connect the unit to the junction timing controller.
