The 25mm next-generation long-range thermal bullet
The Hikvision DS-2TD2638-25/G0/T1Y combines a 25mm long-range thermal lens with the G0 generation thermal sensor. Refined thermal sensitivity, extended detection range past 300 metres on appropriately calibrated zones, and the latest Hikvision thermal processing. The right call for industrial and infrastructure sites where long-range thermal capability and current-generation sensor performance both matter.
What this camera is actually good at
- 25mm thermal lens for very-long-range narrow-field thermal detection.
- G0 generation refined thermal sensor with improved sensitivity.
- Extended detection range past 300 metres on calibrated zones.
- Smart detection events with refined trigger logic.
- IP67 weather-sealed housing.
- Heavy-duty construction for industrial outdoor service.
- Hik-Connect mobile integration.
Where this camera makes the most sense
- Industrial sites with very long perimeters needing current-generation thermal performance
- Power and utilities long-range infrastructure monitoring
- Government and institutional applications with formal thermal specifications
- Agricultural and farming installations protecting valuable assets across large open ground
If you want different range or feature sets
- The DS-2TD2638-35/G0/T1Y pushes the focal length to 35mm for the longest detection ranges.
- The DS-2TD2608-2/QA is the wide-angle thermal alternative.
- The DS-2SF8C425MXS-DL is the bispectrum thermal-and-optical PTZ.

Latest-generation long-range thermal is specialist installation
Mounting structural integrity, precision aiming, vibration mitigation, sensor calibration, and integration all matter. This is industrial commissioning work. We do this across Pretoria East, Centurion, Midrand, and Johannesburg, and nationally for industrial contracts. Contact us for long-range thermal consultations.

How Hikvision HeatPro thermal cameras work
Thermal cameras detect heat instead of light, seeing through smoke, fog, dust, and total darkness. Watch the technology in action.
