Horizontal Directional People Sensor


The DE-10, a counter and estimator device, is designed to count people passing through entrances and passageways. It detects the passage of people and determines their direction. It incorporates our innovative electro-optical approach.

The DE-10 is usually installed on one side of the passageway and requires no receiver on the other side. It will count with some precision when traffic is low, and provide estimates for high traffic periods.

The DE-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 records 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.
  • Directional counts give an extra dimension to your data.
  • When installed in a passageway, the DE-10 will provide a good profile of human traffic through the area.
  • Compact, unobtrusive design.
  • Diecast aluminium case.
    • Adjustable detection zone.
    • Unaffected by speed of passage.
  • 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 or DEL-10.


The sensor is generally placed on one side of the passageway. It detects passage and direction or people, then sends its data to the Data-Logger or the DEL-10.
