Dual-mode detection combines tag-based radio ranging and camera-based tagless detection on the same forklift, so a person can be detected by their wearable tag, by the camera, or by both.
Each technology covers the other’s gap. Ultra-wideband tags range through racking and around corners where a camera has no line of sight, but they miss anyone without a tag. Cameras see untagged visitors and contractors, but only in their field of view and only when lighting allows. Running both on one truck widens coverage, and some systems use agreement between the two to decide how strongly to warn or whether to slow a compatible forklift.
Dual mode adds cost, two sets of hardware to maintain and a tag routine for staff, so it fits sites with both regular workers and frequent untagged visitors, or with blind corners where camera coverage is weak. When evaluating it, ask how the system resolves a disagreement between the two inputs, whether each mode can be configured separately, and how false alerts are handled so drivers do not start ignoring warnings. The proximity warning and camera post explains how the layers fit together.
