Product Description:
The Steinel True Presence BT IPD Presence Detector is the world’s first true presence detector, designed to detect human presence based on micro-movements and vital functions like breathing. With its advanced high-frequency sensor technology, this detector reliably identifies whether a person is present or absent, eliminating unnecessary energy consumption and providing unparalleled accuracy in building automation. The True Presence sensor covers up to 64 m² for True Presence detection and up to 177 m² for general presence and movement detection, making it ideal for spaces such as classrooms, offices, conference rooms, and hotel rooms.
This detector integrates seamlessly with Bluetooth and IP systems, allowing for remote configuration and control. Its surface-mounted design makes installation straightforward and unobtrusive, perfect for both retrofitting and new construction projects. The device is suited for smart building systems, offering easy scalability and interconnection via Bluetooth for flexible building management solutions.

With the introduction of DALI-2, the undisputed lighting control protocol remains DALI. As the acronym suggests "Digital Addressable Lighting Interface" is limited to the lighting domain, however a number of suppliers are blurring the lines attempting to do more.
Building protocols like KNX and BACNet have gateways to DALI.
Backwards DALI compatible, controllers can manage both earlier DALI devices as well as the latest colour tuneable DT8 lights. With a full lighting ecosystem of products, it's sometimes simpler and easier to constrain a solution to DALI alone.
The DALI-2 standard mandates multi-vendor interoperability. Be careful and ask, as some vendors claim DALI-2, yet are still proprietary as they cannot interoperate with other vendors' DALI-2 components.
