Advanced bi-spectrum surveillance built for high-risk environments. The Hikvision DS-2TD1228T-2/QA(B) integrates both thermal and high-definition optical imaging in one turret-camera housing. Designed for demanding installations such as warehouses, manufacturing sites and perimeter areas in South Africa, it offers thermal detection of heat signatures alongside a 4 MP optical sensor for visual verification — delivering comprehensive coverage regardless of lighting or visibility challenges.

Why this camera makes a difference

Conventional visible-light cameras struggle when lighting fails, smoke develops or visibility drops. The DS-2TD1228T-2/QA(B) solves this by pairing a thermal module — capable of detecting heat events and temperature anomalies — with an optical channel for visual clarity and identification. With built-in analytics and high-contrast performance, it offers smarter alerts and deeper insight for your security setup.

Key features & benefits

• Bi-spectrum design: Thermal sensor (256×192 VOx) and optical sensor (4 MP) combined in one unit.
• Thermal detection: Thermal resolution 256×192, pixel pitch 12 µm, NETD ≤ 40 mK (@25 °C, F1.0) — ideal for identifying heat signatures and early fire or hotspot conditions.
• Wide thermal field of view: 2.1 mm thermal lens delivering approx. 90° × 65.4° (H × V) for broad-area coverage.
• Optical clarity: 4 MP progressive-scan sensor with a 2.2 mm lens offering a field of view around 117.8° × 70.4° (H × V) — perfect for visual confirmation of events.
• Smart analytics and temperature alarms: Supports human/vehicle classification, line crossing, intrusion detection and temperature-exception alarms covering ranges from –20 °C up to 550 °C with accuracy up to ±2 °C or ±2 %.
• Outdoor-ready design: Rugged IP67-class weather protection (or equivalent outdoor-rating) and operating temperature from –40 °C to +65 °C — built for South African conditions.

• Fire- or hotspot-monitoring areas such as material stores, incineration plants or enclosed workshops.
• Outdoor installations where lighting or visibility is poor and both thermal detection and visual clarity are required.

Installation & setup tips

• Mount the camera on a stable surface with a clear view of the target zone — ensure both thermal and optical channels are unobstructed.
• Use PoE cabling when possible to simplify power and network connectivity.
• Configure your temperature-exception rules, detection zones and analytics in the web interface or via your NVR for tailored alerts.
• Perform periodic lens cleaning and firmware updates to maintain optimal performance, especially in dusty or exposed outdoor areas.
