Product SKU: HM-TD6368-50C4L/G0/T2Y
Product Overview
The Hikvision HM-TD6368-50C4L/G0/T2Y Thermal & Optical Bi-Spectrum Network Positioning System is a specialised long-range thermal PTZ solution designed for early fire detection, smoke detection, perimeter protection and surveillance across very large outdoor environments. It combines a high-sensitivity 640 × 512 thermal channel with a 50mm thermal lens and a separate 4MP optical camera featuring a 6–336mm motorised lens with 56× optical zoom. Long-range laser illumination up to 2,000m, continuous 360° PTZ positioning, temperature monitoring and intelligent thermal analytics make it suitable for industrial sites, bushfire monitoring, mining operations, ports, substations, waste facilities and critical infrastructure.
Key Capabilities
Long-Range Fire Detection
Dynamic thermal fire-point detection can identify up to 10 fire points, with project reference figures indicating detection of a 1m × 1m fire target from approximately 2,000m under suitable conditions.
Smoke Detection up to 6km
Hikvision specifies smoke detection capability up to approximately 6km for a reference smoke target measuring 5m × 5m.
640 × 512 Thermal Imaging
The 12 μm VOx thermal detector with NETD ≤20 mK provides sensitive heat-signature detection for darkness, difficult lighting and large-area monitoring.
56× Optical Zoom
The separate 4MP optical channel uses a 6–336mm motorised lens to provide detailed visual verification of distant targets and thermal events.
2,000m Laser Illumination
Long-range laser illumination supports optical surveillance of distant targets at night, with illumination intensity and angle automatically adjusted.
Temperature & Perimeter Analytics
Supports temperature exception alarms, line crossing, intrusion, region entrance and region exit analytics for combined fire-prevention and security applications.
Best For
- Bushfire & Wildfire Monitoring: Monitor large areas of bushland, forestry or vegetation for developing heat sources and visible smoke.
- Mining & Industrial Sites: Detect fire, abnormal temperatures, people and vehicles across large remote facilities.
- Waste & Recycling Facilities: Monitor combustible stockpiles and waste areas where heat build-up may indicate an emerging fire.
- Solar Farms & Substations: Combine temperature monitoring, perimeter security and long-distance visual verification.

Why Choose the HM-TD6368-50C4L/G0/T2Y
Choose the Hikvision HM-TD6368-50C4L/G0/T2Y when a project requires considerably more than conventional CCTV. Its thermal channel can identify heat signatures independently of visible lighting, while the optical PTZ channel allows an operator to zoom in and visually investigate detected events. The system is particularly valuable for sites where detecting a developing fire, smoke plume, perimeter intrusion or distant vehicle as early as possible can significantly improve response time. Continuous 360° rotation, long-range laser illumination and intelligent positioning allow a single unit to patrol and investigate very large areas.
Buyer Decision Tips
Fire Detection Example: For project planning, a fire measuring approximately 1m × 1m may be detectable from around 2,000m under suitable reference conditions. Actual range depends heavily on fire intensity, target size, weather, terrain, viewing angle and line of sight.
Smoke Detection Example: Hikvision specifies smoke detection up to approximately 6km using a 5m × 5m reference smoke target. This makes the camera particularly useful for monitoring bushland, industrial sites and large open areas where early smoke detection is required.
Thermal Lens Note: The fixed 50mm thermal lens provides an approximately 8.7° horizontal × 7.0° vertical field of view. It is designed primarily for long-range detection rather than broad short-range coverage.
Power & Installation: This is a large professional positioning system with maximum power consumption of approximately 150W. Structural mounting, power, network infrastructure, lightning protection and access for servicing should be considered during project design.

Choosing the Right Model
- Choose this model if: You need one specialised camera to combine thermal fire detection, smoke detection, temperature monitoring, long-range perimeter analytics and high-powered optical PTZ surveillance.
- Choose the 50mm thermal version for: Long-range monitoring where a relatively narrow thermal field of view is preferred over broad short-distance coverage.
- Consider another thermal lens for: Projects requiring a substantially wider thermal scene or different detection geometry.
- Do not treat reference distances as guarantees: Fire, smoke, human and vehicle detection distances depend on target size, temperature, weather, installation height, background conditions, terrain and line of sight.
- Plan supporting infrastructure: Allow for structural loading, up to 150W power consumption, networking, lightning protection, recording or VMS integration and safe maintenance access.
