Hanwha TNU-X6320A2WT2-C Explosion Proof PTZ Camera

Hanwha TNU-X6320A2WT2-C Explosion Proof PTZ Camera

The TNU-X6320A2WT2-C is a heavy-duty explosion-protected PTZ camera designed for the most demanding hazardous area applications. Built for onshore, offshore, marine, and heavy industrial environments, this 2MP PTZ system combines robust explosion-proof construction with advanced optical zoom and intelligent video analytics capabilities. Its electro-polished 316L stainless steel housing and cLCus/cLC CSA certifications ensure compliance with stringent safety standards while delivering reliable surveillance in Class I, Division 1 and Class II, Division 1 hazardous locations.

Key Features

• 2MP 1920×1080 resolution at up to 60fps in H.265, H.264, and MJPEG formats
• 32× optical zoom (4.44–142.6mm) with 16× digital zoom for detailed subject capture
• 360° endless pan and 180° tilt with 45°/sec and 24°/sec speeds respectively
• Integrated mechanical wiper with UV and ozone-resistant silicone blades
• Explosion-proof design: cLCus C1/D1, cLC CSA, and INMETRO Ex d IIC T4 certified
• IP66 rated weatherproof stainless steel enclosure with toughened glass window
• Auto-iris, auto-focus, and gyro-stabilized image with defog capability
• Dual M25 cable entries for flexible installation and existing conduit compatibility

Technical Highlights

Image Quality & Performance: Superior low-light performance with 0.05 Lux color and 0.005 Lux B/W minimum illumination enables 24/7 monitoring. Advanced WDR (150dB) and HLC processing handle extreme backlit and high-contrast scenarios. WiseStream II bandwidth optimization and triple codec support reduce storage and network demands without compromising coverage.

Explosion-Proof Certification: This camera meets stringent international safety standards including cLCus certification for North American Class I/II hazardous locations, cLC CSA for Canadian compliance, and INMETRO (Brazil) Ex d IIC T4 rating. Optional T5 rating available upon request for elevated temperature environments.

Rugged Construction: Electro-polished 316L stainless steel on all welded assemblies with A4 stainless steel fixings ensures corrosion resistance in marine and chemically aggressive environments. Integral mechanical wiper resists UV, ozone, ice, snow, and extreme temperature fluctuations (-40°C to +60°C standard; T2 variant extends to -60°C).

Intelligent Analytics: Built-in motion detection and intelligent video analytics enable proactive event monitoring. SSDR and SSNR III technology enhance image clarity in challenging lighting conditions.

Applications

• Offshore oil and gas platforms and subsea facilities
• Petrochemical refineries and processing plants
• Marine port and shipping terminal security
• Underground mining and confined space monitoring
• Chemical storage and hazardous material handling areas
• Manufacturing facilities with explosive atmospheres

Network & Protocol Support

Full ONVIF Profile S compliance with comprehensive protocol support including RTSP, HTTPS, DHCP, DDNS, SNMPv3, and QoS enables seamless integration into enterprise security infrastructure. Optional fiber module (single-mode duplex 9/125μm) available for F2 models to support extended-distance fiber connections in high-EMI industrial environments.

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

The TNU-X6320A2WT2-C represents Hanwha's commitment to hazardous area surveillance with a design that prioritizes both safety certification and operational flexibility. The dual M25 cable entries eliminate costly adapters and simplify integration with existing conduit systems—a critical advantage in retrofit installations where downtime must be minimized. The 32× optical zoom paired with gyro-stabilized image delivery and auto-iris provides exceptional detail recovery across the full environmental range, crucial for identifying personnel or equipment status in sprawling industrial complexes.

The triple codec architecture (H.265/H.264/MJPEG) with WiseStream II is particularly valuable in bandwidth-constrained offshore environments where data transmission costs are significant. The 150dB WDR handling combined with defog processing and auto-focus mechanics ensures usable video from dawn through night shifts, eliminating the operational blind spots that compromise safety compliance. For organizations managing multiple hazardous locations, the SNMP v3 and DDNS support enable centralized remote monitoring without dedicated on-site IT infrastructure, reducing operational complexity and cost.
