Smarter Buildings: IoT-enhanced Traffic Analysis Embedded in Lift Sensors

From manual people counters to 3D camera imaging, traffic analysis technology has come a long way in the last few decades. There are various technologies and commercial solutions available in the market today for people counting. Smart devices designed for other purposes, such as light curtains and time-of-flight camera sensors for lift door safeguarding, can have the people counting function embedded in them as well. Thanks to IoT, this sensor data can be computed and visualized for numerous applications, including lift usage optimization and predictive maintenance based on wear and tear. However, the potential of traffic data collected by lift sensors goes beyond the lift itself. It provides valuable insights on people flow in the building as a basis for informed maintenance and business decisions, energy saving, and building usage optimization. As a result, the lift is becoming an important part of the smart building ecosystem.
