Managing foot traffic in outdoor environments — like nature parks, hiking trails, and historical landmarks— requires data, even in places without power or internet. That’s where standalone, battery-operated people counting sensors come in. They allow local governments, municipalities, or private operators to:
- Understand visitor flows and seasonal trends
- Plan maintenance based on footfall volume
- Justify funding with real usage data
- Manage crowding and protect sensitive areas
SensMax offers two popular models for outdoor standalone use:
- SensMax SE — basic one-direction sensor with high battery life
- SensMax DE — bidirectional sensor for IN/OUT counting
