Product SKU: Hikvision HM-TD2638-25/G0/T1Y
Product Overview
The Hikvision HM-TD2638-25/G0/T1Y Thermal & Optical Bi-Spectrum Bullet Camera is a specialist surveillance camera designed for perimeter protection, fire prevention monitoring and intelligent security applications. It combines thermal imaging with optical video, helping operators detect heat signatures, people, vehicles and abnormal temperature events in challenging visibility conditions. With human and vehicle detection plus fire prevention alarm support, it is well suited to warehouses, industrial sites, utilities, car parks, construction areas, storage yards, farms, perimeter fences and critical infrastructure. This model is best selected where standard optical cameras may not provide enough situational awareness in darkness, smoke, glare, fog or complex outdoor environments.
Key Capabilities
Thermal & Optical Bi-Spectrum Imaging
The HM-TD2638-25/G0/T1Y combines thermal and optical imaging to provide both heat-based detection and visible scene detail in one bullet camera.
Human and Vehicle Detection
Human and vehicle detection helps reduce irrelevant alerts by focusing on key security targets across perimeter and outdoor surveillance areas.
Fire Prevention Alarm
Fire prevention alarm support helps identify abnormal heat conditions early, making the camera useful for risk monitoring in industrial and storage environments.
25mm Thermal Lens
The 25mm thermal lens supports longer-distance thermal observation, making it suitable for perimeter lines, yards and larger outdoor detection zones.
Challenging Visibility Support
Thermal imaging can assist detection in darkness, glare, fog, smoke or low-contrast scenes where standard optical cameras may struggle.
Best For
- Perimeter Security: Suitable for fence lines, gates, access roads and large outdoor boundaries requiring thermal detection.
- Industrial Sites: Practical for factories, processing areas, workshops and plant facilities where heat and movement monitoring are important.
- Warehouses and Storage Yards: Useful for monitoring external storage, equipment yards, pallets, materials and high-value assets.
- Fire Risk Monitoring: A good option for sites where early abnormal heat detection may support a broader fire prevention strategy.
- Critical Infrastructure: Best for utilities, substations, logistics hubs, remote facilities and restricted areas requiring enhanced detection.
Why Choose the HM-TD2638-25/G0/T1Y
The HM-TD2638-25/G0/T1Y is a strong choice when a surveillance site needs more than standard visible-light video. Its bi-spectrum design allows thermal detection to identify heat signatures while the optical channel provides visual context, helping operators make better security decisions in difficult environments. Human and vehicle detection helps focus alerts on relevant targets, while fire prevention alarm support makes the camera useful for warehouses, industrial sites and outdoor areas where abnormal heat conditions matter. For systems supplied through Security Wholesalers, this camera should be selected after confirming detection distance, lens suitability, mounting height, scene layout, fire monitoring objective, recorder compatibility and alarm response workflow.
Buyer Decision Tips
Buyer Tip: Choose the HM-TD2638-25/G0/T1Y when you need a thermal and optical bi-spectrum bullet camera with human/vehicle detection and fire prevention alarm support for perimeter or industrial monitoring.
Installation Tip: Confirm required detection distance, thermal lens suitability, optical view, mounting height, camera angle, alarm rules, recorder compatibility, network cabling and environmental conditions before installation.

Choosing the Right Model
- Choose this model if: You need a thermal and optical bi-spectrum bullet camera with 25mm thermal lens, human/vehicle detection and fire prevention alarm support.
- Choose a different camera if: The site needs a wider thermal field of view, closer-range monitoring, PTZ thermal tracking, visible-light-only recording, licence plate capture or a standard fixed CCTV camera.
- Check before ordering: Confirm target distance, lens angle, thermal detection objective, optical scene requirements, mounting position, alarm output needs, recorder compatibility and whether fire prevention monitoring is required.
FAQs
- What is the Hikvision HM-TD2638-25/G0/T1Y used for?
The HM-TD2638-25/G0/T1Y is used for thermal and optical surveillance in security, perimeter protection and fire prevention monitoring applications. It helps detect people, vehicles and abnormal heat events in environments where standard cameras may be limited.
- What does bi-spectrum mean?
Bi-spectrum means the camera combines thermal imaging and optical imaging. Thermal imaging detects heat signatures, while the optical channel provides visual scene detail for verification and situational awareness.
- Does this camera support human and vehicle detection?
Yes. The HM-TD2638-25/G0/T1Y supports human and vehicle detection, making it useful for perimeter security and outdoor monitoring where relevant target detection is important.
- Can this camera help with fire prevention?
Yes. The camera supports fire prevention alarm functionality, which can help identify abnormal heat conditions as part of a broader safety and surveillance strategy. It should not replace certified fire detection systems unless the full site design and compliance requirements support that use.
- Where should this camera be installed?
It is commonly installed on perimeters, industrial sites, warehouses, yards, gates, utility areas and critical infrastructure locations. For systems supplied through Security Wholesalers, placement should be planned around target distance, thermal lens angle and the required alarm zone.
- Why use thermal imaging instead of a standard camera?
Thermal imaging can detect heat signatures in darkness, smoke, fog, glare or low-contrast scenes where a standard optical camera may struggle. It is useful when detection is more important than visible image detail alone.
- Is the 25mm lens suitable for every site?
No. A 25mm thermal lens is better suited to longer or narrower observation zones than very wide close-range scenes. The correct lens should be chosen based on target distance, coverage width and detection requirements.
- What should be checked before installation?
Before installation, confirm target distance, field of view, mounting height, alarm zone layout, thermal detection goal, optical image needs, recorder compatibility, network cabling, power requirements, environmental exposure and the required response workflow for human, vehicle or fire prevention alarms.
