Hanwha TNU-4041T Thermal PTZ Camera 640x480

Hanwha TNU-4041T Thermal PTZ Camera 640x480

The Hanwha TNU-4041T is a professional-grade thermal PTZ camera engineered for long-range surveillance in demanding security environments. Featuring a 640x480 uncooled microbolometer thermal sensor with <50mK thermal sensitivity, this camera delivers precise thermal imaging across day and night conditions, penetrating fog, smoke, and complete darkness where conventional cameras fail. The 19mm fixed focal lens with F1.0 aperture and 32° horizontal field of view enables effective monitoring from 11+ meters, while full PTZ functionality provides dynamic area coverage and investigative capability.

Ted Perry

The TNU-4041T represents a mature thermal PTZ platform optimized for outdoor long-range applications where thermal detection provides critical advantages over visible-light alternatives. The <50mK thermal sensitivity and fixed 19mm focal length prioritize detection range over zoom flexibility—a deliberate trade-off appropriate for perimeter and fixed-coverage scenarios. The 360° endless pan with sub-degree accuracy and 300 presets supports complex multi-zone patrol patterns and rapid response to triggered events.

Integration of advanced analytics—particularly temperature change detection and directional motion analysis—elevates this beyond simple thermal monitoring to intelligent threat assessment. IK10 impact rating combined with IP66 sealing ensures field durability, while the integrated heater addresses thermal imaging challenges in sub-freezing climates. WiseStream II codec optimization reduces bandwidth demands for continuous recording, critical in large-scale deployments.

ONVIF and Wisenet API support ensure flexible integration into mixed-vendor VMS environments. This camera suits organizations requiring unattended long-range thermal surveillance with robust automation and reliability.
