See the invisible. Know what others miss.
The HLK-LD2450 is a 24GHz millimetre-wave radar module at the heart of Prism's most intelligent room-awareness automations. Unlike basic motion sensors, this module tracks the precise position, distance, angle, and velocity of every person in the room — in real time, even when completely still.
In every custom Prism deployment, presence intelligence is the foundation. This sensor is how your home knows the difference between a room that's occupied and one that's empty — and acts accordingly, without you lifting a finger.
