★★★★★ "Covers our full perimeter from four mounting points - the 25mm thermal picks up movement over 150 metres away in complete darkness." - Wynand J., Midrand

Hikvision HM-TD2638-25/G0 - Dual Lens Thermal Bullet Camera with 25mm Thermal and 12mm Optical Lens

The Hikvision HM-TD2638-25/G0 is a high-performance dual lens thermal bullet camera combining a 25mm thermal sensor with a 12mm optical camera and 100m IR illumination. Designed for long-range perimeter security across large industrial, commercial, and critical infrastructure sites, it delivers reliable all-conditions thermal detection and identification-quality optical footage from a single unit. Requires PoE or 12VDC/24VAC power and a compatible NVR or VMS.

Why This Camera Stands Out

• 25mm Thermal Lens for Extended Range Detection - The longer thermal focal length enables reliable human and vehicle detection at significantly greater distances than short-focal-length models - covering large open perimeters from fewer mounting points.
• 12mm Optical Lens with 100m IR - The tighter optical channel with 100m IR complements the extended thermal range, providing identification-quality footage at distance once thermal detection triggers an alert.
• All-Conditions Perimeter Protection - Thermal detection operates through complete darkness, fog, dust, and smoke regardless of ambient lighting - providing reliable perimeter coverage in all weather conditions.

Key Features

• 25mm thermal lens (long-range perimeter detection)
• 12mm optical lens with up to 100m IR illumination
• Perimeter intrusion analytics
• 12VDC / 24VAC / PoE power
• IP67 weatherproof rating
• Compatible with Hikvision NVR and VMS

Why You'll Love It

Large perimeters need cameras that work at range - not just at the fence line. The HM-TD2638-25/G0's 25mm thermal lens detects approaching threats well before they reach your boundary, while the 12mm optical channel with 100m IR captures the identification footage you need once an alert is triggered. Long-range thermal security done right.

FAQ

What is the difference between this G0 model and the G1 variant?
The G0 variant includes standard perimeter intrusion analytics. The G1 variant adds Guanlan advanced analytics - a more sophisticated AI platform that improves detection accuracy and reduces false alarms further, particularly in complex or high-activity environments.

How does a 25mm thermal lens compare in detection range to shorter models?
A 25mm thermal lens typically provides human detection at distances 3-4 times greater than a 3mm lens. For a well-positioned camera, reliable detection of approaching individuals at 150-200m is achievable, making it suitable for large open perimeters and industrial boundary security.

Does this camera work in rain and fog?
Thermal imaging is largely unaffected by rain, light fog, and atmospheric particles. The thermal sensor detects heat signatures independent of visibility conditions. Very dense fog will reduce thermal range, but it will significantly outperform any optical camera in adverse weather. View all FAQs.
