No single company fits every site; a pedestrian detection supplier should be chosen on how well its system matches the hazards, fleet and people where it will run. Check whether it detects untagged people with cameras, tagged people through racking with ultra-wideband (UWB), or both, how it warns the operator and the pedestrian, whether it can slow compatible forklifts, how it performs in your lighting and aisle widths, and how often it raises false alerts. Ask for references at comparable sites, retrofit support for every truck brand you run, and a pilot with agreed success measures before a fleet-wide order.
The full evaluation method is in Choosing a forklift safety system provider, and suppliers are compared in Forklift safety system vendors compared and the vendor directory.
The camera pedestrian detection page explains how tagless systems work and where they miss people, such as behind racking or a raised load. Detection reduces collision risk; it does not replace walkway separation, training or supervision, and OSHA 1910.178 does not require it.
