Hikvision Bi-spectrum thermal bullet 15mm thermal + 4MP 6mm optical 50m IR Fire detection VCA 12VDC/24VAC/POE

★★★★★ "The 15mm thermal lens picks up movement at the far end of our 200m perimeter fence - the detection range is exceptional." - Brenda N., Johannesburg

Hikvision DS-2TD2637-15/QY - Bi-Spectrum Thermal Bullet Camera with 15mm Thermal Lens, 4MP Optical and Fire Detection

The Hikvision DS-2TD2637-15/QY is a bi-spectrum thermal bullet camera combining a 15mm thermal lens with a 4MP 6mm optical channel and fire detection VCA. The 15mm thermal focal length delivers significantly extended perimeter detection range compared to shorter-lens models - ideal for large industrial sites, secure compounds, and critical infrastructure with long perimeter boundaries. Requires PoE or 12VDC/24VAC power and a compatible NVR or VMS.

Why This Camera Stands Out

• 15mm Thermal Lens for Maximum Detection Range - The longest focal length in the bi-spectrum bullet range delivers the greatest detection distance - detecting humans and vehicles approaching large perimeters well before they reach the fence line.
• Fire Detection VCA - Simultaneous fire monitoring alongside perimeter intrusion detection - one camera handles both security and fire prevention for industrial and critical infrastructure sites.
• 4MP Optical Channel with 50m IR - The 6mm optical channel with 50m IR provides identification-quality footage once thermal detection triggers an alert, completing the detection-to-identification cycle.

Key Features

• 15mm thermal lens with fire detection VCA
• 4MP optical channel with 6mm lens
• Up to 50m IR illumination on optical channel
• Fire detection and perimeter intrusion analytics
• 12VDC / 24VAC / PoE (IEEE 802.3af) power
• IP67 weatherproof rating
• Compatible with Hikvision NVR and VMS

Why You'll Love It

When your perimeter runs hundreds of metres and every approach must be detected, the DS-2TD2637-15/QY delivers the range you need. The 15mm thermal lens sees threats in complete darkness at the greatest distances in this camera range, while fire detection runs in the background 24 hours a day. Comprehensive protection for large, high-stakes sites.

FAQ

How does the 15mm thermal lens compare to the 7mm and 3mm models?
Longer thermal focal lengths provide greater detection range but a narrower field of view. The 15mm lens detects individuals at the greatest distance - ideal for long straight perimeters. The 7mm and 3mm models cover wider angles at shorter ranges. Choose based on your perimeter length and mounting positions.

Does the optical channel require its own IR illumination?
Yes. The optical channel has its own built-in IR LEDs providing up to 50m of illumination. This activates automatically in low light for identification footage once the thermal channel has detected a threat.

Can this camera alert a monitoring station directly?
Yes. The camera's alarm outputs can be connected to a monitoring station interface, and when connected to a Hikvision NVR or VMS, alerts can be pushed via email, app notification, or relay output. View all FAQs.
