Dimentions:

100mm x 90mm x 30mm

Functions:

People counting

Typical use:

Determine utilization of meeting rooms vs capacity
Recording of people movement in and out or indoor spaces

Operations:

  • Time of flight directional sensor utilizing a 940 nm invisible laser
  • Two zones (region of interests) measured to detect direction
  • Configurable to ignore door movement
  • Ideally suited for standard door width of 800mm
  • Wider entrances covered by pairing two (or more) Census units
  • Counting accuracy of 95 – 97%
  • Event data is recorded continuously
  • Time and date information of events stored on device for transmission
  • Transmission takes place at predetermined intervals (standard 15 minutes)
  • The transmission interval configurable based on requirement
  • Data Buffering prevents data loss when connectivity is disrupted
