Product Description:
The Steinel HPD2 IP Presence Detector is an advanced optical sensor designed for professional indoor environments where precise occupancy detection and counting are critical. With the ability to monitor up to 10 individually adjustable zones, this sensor is ideal for managing large spaces such as meeting rooms, lecture halls, and open-plan offices. Its 110° detection angle and a range of up to 10 metres ensure comprehensive coverage, whether individuals are seated or standing.
Equipped with IP connectivity, the HPD2 IP supports remote configuration and real-time monitoring through web interfaces, making it a flexible solution for smart building management systems. The detector’s imaging technology compares over 150,000 positive and 7 million negative images in real-time, providing unmatched accuracy in detecting and counting occupants. Designed for surface-mounting on walls or corners, it is a versatile solution for modern, tech-driven environments.

IP has superior network layer hardware, software and data throughput (whether wired or wireless) with decades of tech industry development. All the benefits of a multi-vendor ecosystem persist. Protocols like MQTT and end to end encryption enable the IoT promise, zero-trust security, analytics and data-lakes.
IP device availability is growing strongly, albeit off a low base. The ability to mix topologies and bridge between traditional bus architecture like KNX and IP-based POE devices enables a risk mitigated future-proof solution. Being able to take advantage of the traditional richness of the ecosystem of products (BACNet, DALI, KNX), with a future architecture in place, means the speed of the transition is neutralised.
IP should not be viewed as either/or, rather as both/and.
A final consideration is that there are many more IT engineers than building services engineers which means skills will be more readily available in future.
