Hikvision HeatPro HM-TD2628-3/G1/T3A Bi‑Spectrum Thermal & Optical Bullet Camera – 256×192 VOx, Smart VCA, Fire & Smoking Alarm

Product Overview

For facilities where perimeter intrusion detection and early fire prevention must operate around the clock, the Hikvision HeatPro HM-TD2628-3/G1/T3A combines thermal and optical imaging in a rugged outdoor bullet housing. Its 256×192 vanadium oxide uncooled thermal detector has a 12 µm pixel pitch and NETD of ≤25 mK, providing high thermal sensitivity in darkness and challenging visibility. A 5MP optical channel supplies clear visual verification, while GUANLAN-powered analytics accurately classify people and vehicles to reduce nuisance alarms. The camera also supports temperature-exception alarms from -20°C to 150°C, fire-point detection, smoking detection and sun-reflection filtering. An approximately 70-day lead time applies and should be included in project planning.

Key Capabilities

Best For

• Industrial Perimeter Monitoring: The thermal sensor detects movement through darkness and light obscurants such as smoke or fog where optical cameras alone would miss activity, making it suited to fence line and yard perimeter coverage at factories, depots, and processing facilities.
• Warehouse and Storage Facility Fire Prevention: Temperature-exception and fire-point detection can flag abnormal heat conditions early, supporting faster investigation and intervention.
• Construction Site Security: The vehicle and human classification VCA allows after-hours intrusion detection across large open site areas without generating constant false alerts from environmental movement, supporting unmanned overnight monitoring.
• Critical Infrastructure and Plant Areas: Temperature monitoring across equipment zones and alarm integration provide an automated warning layer where overheating is a concern.
• Outdoor Car Parks and Loading Docks: The 50° thermal field of view and 5MP optical channel cover broad approach areas, while vehicle classification helps separate normal traffic from after-hours intrusion.

Why Choose the HM-TD2628-3/G1/T3A

The HM-TD2628-3/G1/T3A combines a sensitive 256×192 thermal detector, 5MP optical verification and GUANLAN-powered human and vehicle classification in one weather-resistant camera. Compared with entry-level thermal models, its ≤25 mK NETD helps reveal smaller temperature differences, while Smart Hybrid Light provides usable optical evidence after dark. Fire-point detection, temperature-exception alarms, smoking detection and sun-reflection filtering make it suitable for integrators specifying combined perimeter protection and fire-prevention monitoring.

Ideal Use Cases

Choosing the Right Model

• Choose this model if: Your project requires combined perimeter intrusion detection, fire-prevention monitoring, 256×192 thermal imaging, 5MP optical verification and accurate human and vehicle classification in one bullet camera.
• Choose a different model if: Your application is standard optical CCTV without a thermal detection requirement, as a conventional 4MP or 8MP bullet camera will deliver higher optical image detail at significantly lower cost and without the extended lead time. Alternatively, if your site requires precision temperature measurement rather than exception alarms for safety monitoring, a dedicated industrial thermal measurement device would be more appropriate than this camera.
• Choose a different model if: Your project timeline does not allow for the approximately 70-day lead time and an equivalent camera with shorter availability is a higher priority than the 256×192 thermal resolution this model provides.

FAQs

1. What is the lead time for the HM-TD2628-3/G1/T3A?
   This camera carries an approximately 70-day lead time. It is not a stocked off-the-shelf product and must be ordered specifically. Installers and project managers should factor this into procurement schedules well in advance of planned installation or commissioning dates, particularly on staged rollouts across multiple sites.
2. How does the thermal imaging work in complete darkness or through smoke?
   The thermal sensor detects infrared radiation emitted as heat from objects and people rather than reflected visible light. This means it operates independently of ambient lighting and can detect heat signatures through light smoke, fog, or dust where optical cameras would lose visibility. The 256×192 resolution at 12 µm pixel pitch provides sufficient detail to support VCA classification in these conditions.
3. What is the temperature measurement accuracy of the HM-TD2628-3/G1/T3A?
   The camera monitors temperatures across a range of -20°C to 150°C with an accuracy of ±8°C. This level of accuracy is well suited to exception alarms and hotspot detection across equipment, storage areas, and perimeter zones. It is not a precision measurement instrument and alarm thresholds should be configured with sufficient margin above normal operating temperatures to avoid nuisance triggers.
4. What VCA rules can be configured, and how many zones are supported?
   Up to 8 VCA rules can be configured across the scene. Supported rule types include line crossing, intrusion detection, and deep-learning-based vehicle and human classification. This allows the camera to be set up with multiple independent detection zones covering different areas of a perimeter, loading area, or facility yard within a single camera view.
5. What is the difference between fire-point and smoking detection?
   Fire-point detection is intended to identify abnormal thermal hotspots for fire prevention. Smoking detection is a separate analytic intended to detect smoking activity in the monitored scene. It should not be described as a general-purpose smoke detector or used as a substitute for a compliant fire-detection system.
6. What storage options are available for recorded footage?
   The camera supports microSD, SDHC, and SDXC cards up to 256 GB for local recording, as well as NAS-based network storage. ANR (Automatic Network Replenishment) is also supported, allowing the camera to buffer footage locally during a network interruption and automatically upload it to the NAS once connectivity is restored, reducing the risk of footage gaps.
7. Is the HM-TD2628-3/G1/T3A compatible with third-party VMS platforms?
   Yes. The camera supports ONVIF Profiles S, G, and T, along with ISAPI and the Hik-SDK. This provides compatibility with a broad range of third-party video management platforms used in commercial and industrial installations. Up to 20 simultaneous live-view connections and up to 32 user accounts across 3 permission roles are supported. Contact Security Wholesalers if you need to confirm compatibility with a specific VMS before specifying this camera on a project.
