A warehouse pedestrian detection system warns forklift operators, and often the pedestrians themselves, when a person comes too close to a moving truck. It uses one of two methods, or both. Camera-based systems recognize people visually, so they need no tags and detect visitors, but they see only what is in view. Tag-based systems, usually ultra-wideband, can detect workers wearing a tag when they are out of the driver's sight, such as behind racking or around blind corners, but miss anyone without one. Layered systems combine the two, and on compatible forklifts either method can trigger automatic slowdown inside a defined zone.
The full guide is pedestrian alert systems for warehouses. Choose by the gaps on your site. Sites with many untagged visitors, drivers or contractors favor camera detection; dense racking and blind intersections favor tags; busy mixed areas often justify both. Check how zones are set, how alerts reach the pedestrian, how the system logs close calls by location, and what happens when a tag battery runs flat. Detection reduces collision risk where separation is not practical; it does not replace walkways and barriers. The proximity detection page covers tag systems in more detail.
