4S Security

3D LiDAR for building security and occupancy

Spatial sensing that understands presence, movement, and density without cameras, in any space, at any time.

3D LiDAR adds a spatial dimension to your security stack. Where cameras see pixels and access control sees credentials, LiDAR sees the actual movement of people through your building, delivering accurate occupancy, dwell time, and anomaly detection in spaces where other sensors fall short.

True occupancy, not headcounts

3D LiDAR senses presence and movement in three dimensions, so you get accurate occupancy and dwell-time data even in crowded, low-light, or privacy-sensitive spaces where cameras and people-counters fail.

Privacy-preserving sensing

LiDAR sees movement and form, not identity. Monitor bathrooms, locker rooms, galleries, and residential corridors without recording a single identifiable image.

Anomaly and tailgating detection

Spatial awareness lets LiDAR catch tailgating, loitering, and after-hours movement that badge systems and standard analytics miss, with fewer false alarms.

Feeds your unified data layer

LiDAR events stream into the same normalized data layer as your access control, video, and sensors, so occupancy and movement become part of one operational picture.
