Hikvision HM-TD4137-25-WY Bi-Spectrum Thermal PTZ Speed Dome with 25mm Thermal Lens

HikvisionvBi-Spectrum Thermal PTZ Camera

The Hikvision HM-TD4137-25-WY is a bi-spectrum thermal PTZ speed dome camera designed for security applications that require thermal detection and visible-light monitoring in one integrated solution. It combines thermal imaging with optical video to help operators identify activity and assess targets across large outdoor areas. The 25mm thermal lens provides a focused field of view that is suitable for monitoring targets over extended distances.

Dual-Spectrum Surveillance

This camera combines thermal and optical imaging to provide two different views of the monitored environment. Thermal imaging helps detect heat signatures from people, vehicles and other objects, while the optical camera provides visible details for scene assessment. Using both imaging technologies can help security operators understand events more effectively.

25mm Thermal Lens

The integrated 25mm thermal lens is designed for long-distance thermal monitoring. Its focused viewing angle makes it suitable for applications where security teams need to observe specific perimeter areas, access points or distant targets. Thermal imaging can continue to provide useful detection information during darkness and other conditions where conventional visual monitoring may be limited.

Thermal Detection in Difficult Conditions

Thermal technology detects differences in heat rather than relying entirely on visible light. This allows the camera to support surveillance during nighttime operation and in environments affected by low visibility. It can help operators identify people and vehicles that may otherwise be difficult to observe using standard optical cameras alone.

PTZ Speed Dome Control

The speed dome design provides flexible pan and tilt positioning, allowing the camera to be directed toward different areas of interest. PTZ control can help operators monitor a wider section of a property and respond to activity without requiring multiple fixed cameras for every viewing direction.

Flexible Security Monitoring

The camera is suitable for perimeter protection, industrial facilities, infrastructure sites and other large outdoor environments. Operators can use thermal imaging for detection and optical video for visual verification, creating a practical surveillance setup for areas where both awareness and target observation are important.
