The 15mm 2637-series long-range thermal bullet
The Hikvision DS-2TD2637-15/QY is the 15mm long-range thermal bullet from the 2637 series. Detection ranges of 200 to 300 metres on calibrated zones, in a commercial-grade housing built for years of industrial outdoor service. The right thermal camera for sites needing extended-range coverage at multiple perimeter points without going to the flagship-class 25mm and 35mm units.
What this camera is actually good at
- 15mm thermal lens for long-range narrow-field thermal detection.
- Heat-signature detection regardless of light or weather conditions.
- Smart detection events with refined long-range trigger logic.
- IP67 weather-sealed housing rated for industrial outdoor service.
- Heavy-duty construction.
- Hik-Connect mobile integration with thermal-triggered alerts.
Where this camera makes the most sense
- Industrial and commercial perimeters with multiple long-range coverage points
- Larger farms and smallholdings with extended fence lines and access roads
- Power and utilities long-range monitoring
- Storage and warehousing perimeters at industrial sites
- Government and institutional perimeters
If you want different range or features
- The DS-2TD2637-10/QY is the 10mm medium-range variant.
- The DS-2TD2608-2/QA is the wide-angle thermal alternative.
- The DS-2TD2608-2/QA/FP adds fire detection.
- The DS-2TD2638-25/G0/T1Y pushes to 25mm for longer-range applications.
Recorder pairings
Pairs cleanly with the DS-7616NXI-K2 16-channel NVR, or commercial-grade NVRs like the DS-7732NXI-I4/16P/S.
