Infrared sensors - Technical specifications
Presentation
The infrared sensor is a crowd counting system based on infrared technology.
The infrared sensor is made of two small units with two parallel infrared beams. When the infrared beams are crossed by someone an entry or an exit is measured. The access is measured as an entry or as an exit depending on the infrared beam firstly crossed.
The data measured is then sent by radio waves (2,4 GHz) to a data collector plugged at a distance between 0 and 20 meters, which ultimately transmit the information through 3G/4G network towards Affluences servers to be analysed and processed.
The infrared sensor is an ergonomic crowd counting system, which is also autonomous, easy to configure and flexible when implemented.

Installation
Step 1: Prerequisite
Crossing point: width inferior to 5 meters
Step 2: On site-installation
Positioning the Infrared sensor (height between 80cm and 135cm), based on the installation instructions
Fixing the infrared sensor
Checking the data collection
Step 3: Post-installation follow up
Checking measured data relevance and adjusting with a correcting ratio if required
Commissioning the infrared sensor (data get published on the information tools)
Examples
Example of black infrared sensors
Accessories: Pole
Optional metal support pole are available for passages where sensors cannot be installed on either side of the passage, or on existing supports.
The poles must be fixed to the ground (screwed or glued with strong glue) to prevent the sensors from shifting and rendering the counting inoperative.
Height : 1m
