The FP400 can track up to ten people, offers a 0.5 × 0.5 m grid for zone placement, and supports up to eight zones for granular automation. It features AI‑assisted spatial learning to reduce false triggers and includes an ambient light sensor and adjustable sensitivity levels. The unit requires USB‑C power and has no battery option.
