Directional People Sensor


The DS-10 is designed to count people passing through entrances and doorways. It detects the passage of people and determines their direction. It incorporates our innovative electro-optical approach.

The DS-10 series can be enclosed in an array of multiple sensors to cover very wide doors. This device is  now installed in thousands of entrances . It gives an excellent precision on the counts.  Its accuracy, certified by our customers,  reaches  95%.

The DS-10 is generally used in conjunction with a DL-10 Data-Logger which carries out, for each sensor, hundreds of calculations and analyses per second, determining the number and direction of people and recording other data such as the date and time.


  • Its customizeable appearance blends in with the surroundings, making it virtually unnoticeable.
  • Its adjustable sensitivity ensures strollers and shopping carts are not counted.
  • User-certificed accuracy levels make your data trustworthy.
  • Directional counts give an extra dimension to your data.
  • Vertical counting ensures no one is hidden behind another person.
  • Compact, unobtrusive design.
  • Diecast aluminium case.
    • Adjustable detection zone.
    • Unaffected by speed of passage.
    • Unaffected by immobile passengers.
  • Very effectively separates people following each other closely.
  • Withstands environmental stresses common to buildings.
  • Easily installed and readily linked via conventional 4-cable conductors.
  • Powered by a DL-10 Data Logger.


The sensor is generally placed on top of the vehicle doors. For wide entrances, a multiple sensor configuration is available. It detects passage and direction of people, then sends its data to the Data Logger.Optics:Type: Passive opticsMaximum height: 2 m / 6,7 ft. to 2,6 m / 8,5 ft.*Maximum coverage**- 76,2 cm / 2,5 ft.- AC and BC: 1,22 m / 3,5 ft.* Special configuration for 11-foot heights available.** For one sensor.
