People flow sensors

Detect people going in and out of a doorway automatically, and in real time

Our people flow sensors detect when a person walks towards or away (bi-directional) from the sensor. The small sensors are mounted above a single doorway and send a message each time a person enters or exits through the doorway. You can use the data to report people flow in/out of a room in real-time or count how many people have entered or exited a room.


Get instant people in/out updates

Our people flow sensor is designed to be mounted above a single doorway to detect the in- and out-flow of a room. USB to DC mains-powered for easy installation.


Accurate, privacy-compliant monitoring

The people flow sensor uses time of flight technology to detect when a person walks towards or away from it. No cameras. No interference from glass reflections. Fully anonymous.


Access real-time data locally or in the cloud

People flow data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.


  • Mounted above a single doorway. Detects real-time people flow in/out through a single doorway
  • Time-of-flight sensor detects people and the direction of movement (bi-directional)
  • Accuracy: 86-98%. Comes with a mounting bracket to minimise door interference
  • Detection range depends on height of sensor. Based on a 2.5m high single door, movement is detected 1.2 metres across the door and 0.6 metres into the door from the centre of the sensor
  • Privacy and GDPR compliant: sensors only detect people
    movement. No cameras. Fully anonymous
  • 5V USB to DC mains adapter
  • Transmit data wirelessly and securely – using AES-128 encryption – via EnOcean wireless protocol, which uses internationally approved, licence-free ISM bands
    • 868 MHz for Europe (RED)
  • EnOcean Equipment Profile (EEP): D5-00-01
  • No recurring fees. Access the data through your chosen platform, without any additional costs from Pressac
  • Manufactured in the UK to high-quality and high-safety specifications, they are subject to rigorous testing procedures
  • Dimensions: 67 x 124 x 35 mm (approx)
