Hanwha TNU-4051T Thermal PTZ Camera 640x480

Hanwha TNU-4051T Thermal PTZ Camera 640x480

The Hanwha TNU-4051T is a long-range thermal PTZ camera engineered for mission-critical surveillance in demanding environments. Built on an uncooled micro bolometer imaging platform with 640x480 resolution and 17μm pixel size, this camera delivers exceptional thermal sensitivity (≤50mK NETD) to detect minute temperature variations across vast perimeters. Its 35mm fixed focal length with F1.0 aperture and 17.2° horizontal field of view enable detection at distances exceeding 118 feet, making it ideal for infrastructure protection, perimeter security, and large-area monitoring where traditional visible-light imaging falls short.

Key Features

• 640x480 uncooled thermal sensor with ≤50mK thermal sensitivity
• 360° endless pan with speeds up to 120°/sec; tilt range -90° to +40°
• Preset positioning with 300 presets and ±0.3° accuracy
• Built-in gyro sensor for digital image stabilization
• IP66/NEMA4X rated aluminum housing for outdoor durability
• PoE powered with low consumption (62W–84W depending on heater mode)
• Multiple color palettes including Whitehot, Blackhot, Rainbow, and custom options

Advanced Analytics & Detection

The TNU-4051T integrates comprehensive onboard analytics: directional detection, motion detection with 8-point polygonal zones, appear/disappear, enter/exit, loitering, tampering, virtual line crossing, temperature change detection, audio detection, shock detection, and sound classification. Alarm outputs trigger on analytics events, network disconnect, or direct input, with support for FTP upload, email notification, and SD/NAS recording at event activation. Direction indicator and up to 85-character camera title overlay aid in operational clarity.

Streaming & Codec Support

Video compression via H.265/H.264 (Main/Baseline/High) or MJPEG at up to 30fps/25fps (60Hz/50Hz). Smart codec WiseStreamII reduces bandwidth with CBR or VBR bitrate control. Supports unicast (20 users) and multicast streaming with up to 10 simultaneous profiles. Audio input (selectable mic/line, 2K Ω impedance) and line output (1Vrms max) with G.711/G.726 compression enable integrated audio monitoring.

Networking & Security

IPv4/IPv6 dual-stack with TCP/IP, UDP/IP, RTP, RTSP, HTTP/HTTPS, SMTP, SNMP v1/v2c/v3, DDNS, UPnP, and LLDP. ONVIF Profile S/G/T compliance ensures cross-platform integration. 802.1X (EAP-TLS/EAP-LEAP) and SSL/TLS login authentication with IP filtering and user access logging secure all communications.

Applications

• Perimeter intrusion detection for critical infrastructure
• Border and fence-line monitoring in adverse weather
• Industrial site surveillance in low-light and smoky environments
• Airport, port, and logistics hub coverage
• Night-time security operations without visible light pollution
• Temperature anomaly monitoring in power plants and refineries

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The TNU-4051T addresses a critical gap in outdoor surveillance: thermal imaging with motorized pan-tilt-zoom control. Its 360° endless pan and preset-driven positioning eliminate blind spots across sprawling sites, while thermal sensing penetrates darkness, fog, and smoke that defeat conventional cameras. The ≤50mK NETD sensitivity ensures detection of personnel and vehicle-scale thermal signatures at extended range.

IP66/NEMA4X construction and -40°C to +55°C operating range handle arctic and desert deployments without performance degradation. Onboard analytics—particularly temperature change detection and directional motion—enable intelligent alerting in unattended perimeter operations, reducing false alarms. The 30fps frame rate with H.265 codec balances real-time responsiveness and bandwidth efficiency critical for remote infrastructure sites with limited connectivity.

For organizations prioritizing thermal detection over visible spectrum imaging, the TNU-4051T delivers enterprise-grade reliability at the intersection of long-range surveillance and intelligent automation.
