DS-2TD4137-25/WY Thermal Bi-Spectrum PTZ 25mm

The 25mm bi-spectrum thermal PTZ

The Hikvision DS-2TD4137-25/WY is a thermal bi-spectrum PTZ camera. 25mm thermal lens for heat detection at extended distance, combined with a 2MP 25x optical zoom module, full pan-tilt-zoom motor control, and Hikvision PTZ smart tracking. The thermal channel detects intruders in conditions where standard cameras are blind (smoke, dust, total darkness), the PTZ follows them automatically, and the optical channel provides standard CCTV imagery for visual identification once the camera is on the target.

The right call for industrial perimeter monitoring with active control room coverage: heavy industrial sites, mining operations, agricultural facilities, and any environment where standard CCTV is failing because of dust, smoke, or extreme darkness, AND the operator needs active PTZ control to follow detected events.

What this camera is actually good at

• 25mm thermal lens with extended detection range.
• 2MP optical channel with 25x optical zoom.
• Full pan-tilt-zoom motor control.
• Smart tracking following detected thermal events automatically.
• Bi-spectrum design with simultaneous thermal and optical channels.
• Detection through smoke, dust, and total darkness.
• Heavy-duty IP66 weather-sealed housing.

Where this camera belongs

• Heavy industrial site perimeter monitoring with active control room coverage
• Mining operation perimeter applications
• Agricultural facility boundary monitoring
• Critical infrastructure with combined thermal-detection and active-PTZ requirements

If you want longer thermal range or different feature set

• The HM-TD4137-50/WY is the 50mm extended long-range alternative with 4MP and 40x zoom.
• For fixed-bullet thermal alternatives, see the HM-TD2638 dual-lens thermal range.

Network keyboard control

Thermal PTZ deserves proper joystick control. Pair with the DS-1200KI_C network keyboard or the DS-1600KI_C for larger control rooms.

Thermal PTZ projects are genuinely site-specific and need detailed survey work before specification. Contact us for thermal PTZ projects across Pretoria East, Centurion, Midrand, and Johannesburg.
