Optical presence detector thePixa KNX: Optimise building automation & building operation

The optical presence detector, thePixa KNX, detects how many people are in a room and where they are. This information is used to trigger predefined actions in the KNX building control system. It's not just the building automation features that stand to gain – there are completely new benefits, especially for building operators. For example, flexible options for configuring desk-sharing or for optimising room occupancy and building cleaning activities.

For decades, classic Presence detectors with passive infrared technology have controlled the lighting and indoor climate of many rooms in a sustainable and energy-efficient manner. They detect people accurately and reliably based on their body heat and movements. The pixel-based detection technology of thePixa KNX optical presence detector opens up further applications with enhanced value, extending far beyond the scope of PIR presence detectors.

German Innovation Award 2021

Award-winning innovation

thePixa optical presence detector sets a milestone in the advancement of presence detector technologies. thePixa was recently awarded the German Innovation Award 2021. The jury's rationale emphasised, among other things, the versatile utilisation concepts, the easy-to-use app control, the high degree of user-centricity as well as the outstanding design of the Stuttgart-based design studio ID AID featuring clear, minimalist aesthetics. They also highlighted the added safety benefits during pandemics offered by the information on occupancy density.

DEKRA approved

GDPR-compliant capture

thePixa KNX uses very low-resolution images and therefore fully complies with GDPR requirements (DEKRA-tested*). Using image analysis, the optical presence detector identifies changes in the situations that arise in the rooms being monitored and processes the associated information. thePixa can then detect how many moving objects are within the detection area and count them. The grid function displays a view of the current data provided by thePixa. With this process, the image of the room shown does not represent as a live recording, but a static background image.

Impressive added value

The detection result is visually processed in the form of a heat map and can be called up together with detailed occupancy statistics in thePixa Plug app. This information triggers a predefined action in the KNX building control system, such as starting up the ventilation system in a fully occupied meeting room.

The visualisation of detected areas by means of the heat map offers building operators a great deal of added value. Product presentations in department stores can be optimised by identifying which products customers stop to look at most often and show the greatest interest in. Valuable information can also be obtained in office facilities: by identifying which workstations are used more or less often, it is possible to access advantages such as efficient desk-sharing management. This allows for a flexible response to peak workloads. Operating and energy costs for buildings can be reduced. 

Easy app programming

Using thePixa Plug app, the detection area can be divided into up to 6 zones and freely programmed if desired. The precise subdivision of the detection area, with dimensions up to 11 x 15.5 m, enables accurate lighting control in larger rooms and prevents false switching operations.

The high installation costs that are often incurred after conversion or room restructuring are completely eliminated. It is easy to create new zones within the detection area in the app. It is also possible to set up exclusion zones in which detected movements do not trigger any actions using thePixa Plug, for example in production facilities. The settings programmed in the app are then simply transferred from a smartphone or tablet to thePixa via Bluetooth.

thePixa mounting and installation:

thePixa uses its flexible zone configuration (up to 6 zones are possible) not only to record how many people are in the room, but also where they are. This opens up completely new applications for planners, architects, shop owners and system integrators. In order for flexible desk-sharing models to come into play, the optimization of room occupancy succeeds perfectly and predefined actions in the building automation are triggered correctly , there are a few points to consider. Our video on the mounting and installation of the optical presence detector shows how this works.
