Look for detection that covers people with and without tags, alerts that reach both the driver and the pedestrian, zones and alert distances you can configure by area, automatic speed reduction on compatible forklifts, and event logging with reports a safety team will actually use. Also check how the system tells people from objects, since nuisance alarms are a main reason crews stop trusting warnings, and whether it can be managed the same way across several sites. Ask for a pilot in your highest-traffic zone and judge it on missed detections and false alerts, not on a demonstration.
The full guide is Forklift pedestrian warning system: what to look for, which expands each feature. A few checks are easy to skip. Find out whether speed control needs a CAN-bus connection or a separate interface on your truck models, and how that affects the truck warranty. Confirm tag battery life, the charging routine and how tags are issued to visitors and temporary staff. Ask who owns the event data, how long video is kept and who can view it, which the AI camera privacy guide covers. Finally, read the maintenance terms: detection that drifts after installation gives a false sense of cover.
