Use of sensor technology

The University is currently trialling three devices (OccupEye, Brickstream and HPD2) that monitor the occupancy levels of key spaces on campus.  This technology will help the University make efficient use of space on campus and provide students with real-time occupancy information. This occupancy data will enable students to quickly and easily identify available study space. The occupancy data is available on the Study Spaces  website.

Frequently asked questions 

What are OccupEye, Brickstream and HPD2 devices?

OccupEye is a PIR (passive infra-red) sensor that is placed under desks to detect if the desk is in use by monitoring movement.

Brickstream is a stereoscopic infra-red sensor that detects movement using thermal imaging. 

HPD2 uses a passive optical sensor to create and analyse a static image of a given space.

What do the sensors do?

The OccupEye sensors are placed under desks in some spaces on campus and can detect movement. This provides real-time data on desk availability.

The Brickstream devices are placed above doorways and use thermal imaging to count the number of people entering and exiting a room. This provides real-time room occupancy data.

The HPD2 devices are placed at high level in a space and use capture temporary still images. These are then analysed to determine the real-time occupancy of the space. The images never leave the device and cannot be used to identify individuals.

Can this technology identify individuals?

Neither the Brickstream or Occupeye sensors can record images or sound, and cannot be used to detect identity. The Steinel devices do capture a temporary image, but this image is immediately deleted once analysis is complete (after around 30 seconds) and therefore cannot be used to identify individuals.

Who is the supplier of this technology?

The devices are supplied by CadCapture (Brickstream and Occupeye) and Steinel (HPD2).

Why is the University investing in this technology?

Students have told us that they want information on the availability of study spaces to be easily accessible. This system will provide students with accurate up-to-date space occupancy data to help them determine where they would like to study. The University will also be able to use this data for future developments and enhancements to campus; this could include improvements linked to room bookings, building management and energy use. 

Where are the sensors currently installed on campus?

The sensors are used in key study locations such as The Link, The Loft, Mason Lounge, and The Learning Centre. Please contact us via the email below if you would like more information.
