The Hikvision DS-2TD1228T-2/QA(B) is a professional HeatPro bi-spectrum network turret camera engineered for advanced thermal monitoring, perimeter protection, and early fire warnings. Featuring an ultra-sensitive 256 × 192 resolution thermal module and a high-definition 4MP optical camera, this IP67 weather-protected camera delivers excellent visibility in all lighting conditions. With its built-in deep learning target classification, it represents an outstanding security asset for demanding commercial and industrial properties.
Hikvision DS-2TD1228T-2/QA(B) HeatPro Bi-Spectrum Turret Camera
This premium bi-spectrum turret camera is designed for security systems that require both visual surveillance and precise temperature monitoring. The thermal sensor features a 256 × 192 resolution with a 12 μm pixel pitch and a thermal sensitivity (NETD) of ≤ 35 mK. This high sensitivity allows the camera to detect minute temperature differences and spot anomalies early, which is essential for fire prevention and critical infrastructure security. The 2.1mm fixed thermal lens delivers a wide 90.0° × 65.4° field of view, providing a broad coverage zone for close-range targets.
The optical module boasts a 1/2.7" Progressive Scan CMOS sensor delivering a 4MP (2688 × 1520) resolution, accompanied by a 2.2 mm lens. The bi-spectrum feature allows the system to overlay thermal and optical images (bi-spectrum image fusion), providing security personnel with a highly detailed composite view that facilitates faster object recognition and decision-making.
Advanced Bi-Spectrum Image Fusion
Unlike standard thermal cameras, the DS-2TD1228T-2/QA(B) features advanced bi-spectrum image fusion technology. This blends the visual details of the 4MP optical sensor with the thermal heat map from the VOx detector. The fused image allows operators to identify outlines, text, and specific objects much faster, removing the ambiguity of standard thermal-only feeds.
Note: This model supports high-accuracy temperature measurements ranging from -20°C to 550°C (-4°F to 1022°F) with a precision of ±2°C or ±2%. You can configure up to 21 measurement rules simultaneously across points, lines, and areas.
AI-Powered Perimeter Protection
Integrated deep-learning algorithms classify moving targets into human and vehicle categories. This advanced classification filters out false alarms from leaves, animals, rain, and light changes, ensuring that security alerts are highly accurate and actionable. It supports line crossing, intrusion detection, and region entrance/exit rules.
Early Fire & Smoking Detection
The DS-2TD1228T-2/QA(B) features dedicated fire and smoking detection algorithms. By analyzing temperature rises and specific flame shapes, the camera can detect fires in their earliest stages, generating rapid alerts before visible smoke or flames reach traditional fire sensors.
Rugged IP67 and Anti-Corrosion Build
Housed in a robust IP67 weather-resistant enclosure, the camera is designed to withstand extreme outdoor conditions, including heavy rain, dust, and freezing temperatures. Its compact turret form factor allows for flexible ceiling or wall mounting.
Secure Communication and Edge Recording
The camera supports advanced network encryption including HTTPS, SSL/TLS, and 802.1X. It features a built-in MicroSD slot supporting up to 256 GB cards for local backup recording during network dropouts, ensuring no security footage or thermal data is lost.
