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.

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.
