VOS (Volumetric Object Surveillance)
Sculptures and 3D Artworks
VOS sensors analyse changes in infrared light reflectivity within a 3D volume surrounding objects using 3D MLI Sensor™ Technology. They detect any physical approach within a three-dimensional space or any movement or alteration of an object therein. By setting multiple early alarm zones, it’s possible to raise audible local pre-alarm warnings if visitors cross one ‘curtain’, but only to raise a full alarm with security if they cross another ‘curtain’ nearer the asset(s). The device can be mounted discretely overhead, either flush with or suspended from the ceiling.
