Product SKU: Hikvision DS-2TD4167T-25/W
Product Overview
The Hikvision Thermal & Optical DS-2TD4167T-25/W Bi-Spectrum Network Speed Dome Camera is a professional thermographic surveillance solution designed for temperature monitoring, fire prevention, perimeter protection and long-range optical verification. It combines a 640 × 512 thermal channel with a 25mm thermal lens and a 4MP optical channel with a 6–240mm motorised lens and 40× optical zoom. The thermal channel supports temperature exception alarms, fire detection, thermal image enhancement and target coloration, while the optical channel provides 120dB WDR, optical defog and detailed visual confirmation. With smart tracking, perimeter protection, 200m IR, alarm I/O, microSD support and IP66 protection, it is ideal for factories, substations, hydropower sites, industrial yards, perimeter security, storage facilities and high-risk temperature monitoring applications.
Why Choose the Hikvision DS-2TD4167T-25/W
The Hikvision DS-2TD4167T-25/W is ideal for sites that need more than standard video surveillance. Its thermal channel can detect temperature exceptions, fire points and heat signatures in difficult visibility conditions, while the optical channel provides high-detail colour video for verification and investigation. The 25mm thermal lens supports focused thermal monitoring, and the 40× optical zoom allows operators to visually inspect distant targets after a thermal or perimeter event. Deep-learning perimeter protection helps detect line crossing, intrusion, region entrance and region exit events, while smart tracking can support panorama tracking, event tracking and multi-scene patrol tracking for large or complex sites.
Key Capabilities
Thermal and Optical Bi-Spectrum Monitoring
The camera combines a thermographic thermal channel and a 4MP optical channel in one speed dome. This allows users to detect heat, monitor temperature exceptions and visually verify incidents with optical zoom from the same device.
Temperature Measurement and Fire Detection
The DS-2TD4167T-25/W supports temperature measurement rules, temperature exception alarms and dynamic fire detection. This makes it suitable for monitoring pyrophoric materials, industrial processes, energy sites, storage areas and other heat-risk environments.
40× Optical Zoom Verification
The optical channel includes a 6–240mm lens with 40× optical zoom, allowing operators to move from a wider optical view to close-up verification of distant people, vehicles, heat events, process areas or perimeter activity.
Deep-Learning Perimeter Protection
Perimeter protection functions use deep learning to support line crossing, intrusion, region entrance and region exit detection. This helps improve event accuracy across restricted zones, fence lines, gates, industrial yards and high-security boundaries.
Smart Tracking and PTZ Control
Smart tracking supports panorama tracking, event tracking and multi-scene patrol tracking. The PTZ mechanism provides 360° continuous pan, tilt from -20° to +90°, presets, patrols and pattern scans for flexible wide-area monitoring.

Understanding Thermographic Bi-Spectrum Monitoring
The DS-2TD4167T-25/W combines thermal detection and optical verification in one PTZ speed dome. The thermal channel detects heat signatures and temperature exceptions, making it valuable for fire prevention, process monitoring and perimeter detection in low-visibility conditions. The optical channel then provides visual confirmation with 4MP resolution, 40× optical zoom, WDR and defog support. This bi-spectrum workflow helps operators detect hidden risks early, verify the source visually and respond faster to security, safety or process events.
