Traffic Count, Vehicle Speed and Length

The TDC1-PIR  traffic detector is a highly accurate traffic counter with radar-like speed accuracy, length based vehicle classification and ultra-low power consumption.  It has been specifically designed for applications where both power consumption and accurate data are the deciding factors.

Order No.: 10000, 10002


  • PIR


  • Ultra-low power consumption
    ≤60 mW, ideal for solar powered installations
  • Multi channel PIR detection
    Total of five detection zones
  • Vehicle classification by length
    3 standard classes, up to 5 vehicle classes possible (depending on customer length threshold setting)
  • Auto calibration
    Auto calibration within recommended mounting distance from the centre of the observed lane using ADEC DET-Soft commissioning software
  • Wide mounting height range
    Mounting height between 5.5 m and 18 m (max. offset 45º from detector’s mounting location to the centre of the observed lane), Application-dependent limitations apply
  • Detection of standing vehicles
    Queue detection
  • Detection of wrong-way drivers
  • Wide operating temperature range
    –40 to +70ºC (–40 to +158ºF) Optimal performance in all weather and climate conditions
  • Remote configuration and setup
    Using DET-Soft commissioning and installation software


ADEC TDC1-PIR detector is specifically designed for a variety of traffic data collection and traffic control applications, whether low power consumption is essential or not:

  • Vehicle counting / traffic volume
  • Individual vehicle speed
  • Vehicle classification (by vehicle length)
  • Presence detection
  • Queue detection for queue warning systems
  • Wrong-way driver detection for wrong-way driver alert system
