HM-TD2638-35/G1/T3Y Dual-Lens Thermal Bullet 35mm

The 35mm extended long-range thermal bullet

The Hikvision HM-TD2638-35/G1/T3Y is the longest-range dual-lens thermal bullet in the current G1 range. 35mm thermal lens for extended-distance thermal detection, 12mm optical lens for bi-spectrum imagery, and 100m IR illumination. The right call for very-long-perimeter thermal applications: large estate boundary runs, mining-site perimeter coverage, agricultural-operation boundary monitoring, and any thermal CCTV scenario where the 25mm sibling does not give enough detection distance.

What this camera is actually good at

• 35mm thermal lens for extended-distance detection.
• 12mm optical lens for bi-spectrum imagery.
• 100m IR illumination on the optical channel.
• Longest-range thermal detection in the dual-lens bullet range.
• IP67 weather-sealed housing.

Where this camera belongs

• Large estate boundary runs requiring extended-distance thermal coverage
• Mining-site perimeter monitoring
• Agricultural operation boundary applications
• Critical infrastructure with very long perimeter sections

If you want shorter focal length

• The HM-TD2638-25/G1/T3Y is the 25mm long-range alternative.
• The HM-TD2638-15/G1/T3Y is the 15mm medium-range alternative.

Extended-range thermal applications need detailed site survey: thermal contrast considerations, mounting position relative to the detection zone, and integration with the broader site infrastructure.
