Hikvision DS-2TD2528T-7-Q 256×192 Outdoor Thermography Thermal Camera with Temperature Measurement 7mm Lens

Product SKU: DS-2TD2528T-7-Q

Product Overview

The Hikvision DS-2TD2528T-7/Q is a thermographic bi-spectrum network bullet camera designed for industrial temperature monitoring, perimeter protection and fire-prevention applications in demanding outdoor and hazardous environments. Its thermal module uses a 256 × 192 vanadium oxide uncooled focal plane array with a 7 mm F1.0 lens, while the separate optical channel captures up to 2688 × 1520 resolution through a 4 mm lens. The camera measures temperatures from -20°C to 550°C with a stated maximum accuracy of ±2°C or ±2%, supporting point, region and line-based thermography rules. A 316L stainless-steel housing, IP68 protection, ATEX and IECEx explosion-proof certification plus NEMA 4X and C5 anti-corrosion protection make it suitable for specialised industrial and critical-infrastructure surveillance.

Key Capabilities

Best For

• Industrial Thermography: Suitable for monitoring abnormal temperature changes around machinery, electrical systems, process areas and other heat-critical equipment.
• Fire Prevention: Thermal imaging can help identify abnormal heat conditions before they become visible through a conventional camera.
• Hazardous Areas: ATEX and IECEx certification support deployment in compatible explosion-proof industrial environments.
• Corrosive Environments: 316L stainless steel, NEMA 4X and C5 anti-corrosion protection suit demanding industrial sites.
• Perimeter Monitoring: Thermal VCA remains useful in low-light or visually difficult conditions where conventional optical detection can be less reliable.

Why Choose the DS-2TD2528T-7/Q

The DS-2TD2528T-7/Q is designed for specialist environments where ordinary CCTV cannot provide the same level of thermal awareness. Its 256 × 192 thermal detector, broad -20°C to 550°C measurement range and configurable point, line and area thermography rules make it useful for condition monitoring and abnormal-temperature detection, while the 2688 × 1520 optical channel provides visual confirmation of what is happening in the scene. The 316L stainless-steel explosion-proof housing also makes the camera suitable for harsh industrial locations. Available through Security Wholesalers, it is particularly valuable where thermography, perimeter protection, corrosion resistance and hazardous-area certification all need to be combined in one camera.

Ideal Use Cases

Choosing the Right Model

• Choose the 7 mm version if: You need the 24.9° × 18.7° thermal field of view and the monitored target size and distance suit this lens.
• Choose a wider thermal lens if: The priority is covering a broader nearby area rather than concentrating thermal pixels on a narrower scene.
• Choose this model if: The project requires thermography, optical verification, explosion-proof certification and 316L stainless-steel construction in the same camera.
• Confirm hazardous-area design if: The camera will be installed in a certified explosive atmosphere, as the camera alone does not make the complete installation compliant.

FAQs

1. What thermal resolution does the Hikvision DS-2TD2528T-7/Q provide?
   The Hikvision DS-2TD2528T-7/Q uses a vanadium oxide uncooled focal plane array with 256 × 192 thermal resolution, 12 μm pixel pitch and NETD below 40 mK at 25°C with an F1.0 aperture. The 7 mm thermal lens provides a 24.9° × 18.7° field of view and a minimum focusing distance of approximately 0.5 metres.
2. What temperature range can the DS-2TD2528T-7/Q measure?
   The DS-2TD2528T-7/Q supports temperature measurement from -20°C to 550°C. Hikvision specifies a maximum temperature accuracy of ±2°C or ±2%, whichever is greater.

3. Does the DS-2TD2528T-7/Q include an optical camera as well as thermal imaging?
   Yes. The DS-2TD2528T-7/Q is a bi-spectrum camera with a 256 × 192 thermal module and a separate optical module using a 1/2.7-inch progressive scan CMOS sensor. The optical channel captures up to 2688 × 1520 resolution through a 4 mm F1.6 lens with 120 dB WDR, allowing thermal and visible-light information to be used together.
4. Can the DS-2TD2528T-7/Q detect fire or abnormal temperatures?
   Yes. The camera is designed for thermography applications and supports temperature measurement rules and alarm actions when monitored temperatures exceed configured limits. Its thermal imaging and temperature analytics make it suitable for early identification of abnormal heat conditions in supported industrial and critical-infrastructure applications. It also supports perimeter VCA functions including line crossing, intrusion, region entrance and region exiting.
