The Hikvision DS-2TD4228T-10/S2 is a high-end bi-spectrum PTZ surveillance camera designed for demanding environments where both thermal sensing and high-resolution optical zoom are needed. It merges thermal imaging for detection (including temperature anomalies and fire/smoke) with optical imaging for identification, and supports intelligent tracking and perimeter protection features.

Use Cases
-
Industrial / Power Substation Monitoring
Excellent for places like power generation / distribution sites, refineries, factories, where heat anomalies (e.g. overheated equipment) need detection, plus visual confirmation and PTZ zoom to inspect details. -
Fire-Prone Areas
Locations at risk of fires (wood lots, chemical storage, transformer stations etc.), where both early thermal detection and smoke / fire detection features can trigger alarms before visible flames. -
Perimeter Security in Critical Infrastructure
Border fences, utility perimeters, airports, chemical plants etc., where intrusion detection under any lighting or weather, as well as visual identification, is required. -
Transport & Heavy Industry Environments
Rail yards, ports, mining operations etc., where conditions can be harsh, and both thermal and optical imaging are used to detect hazards, monitor operations, or detect persons/vehicles. -
Shift operations & Remote Sites
Remote unmanned installations where automatic alerts (temperature, intrusion) are needed; the optical zoom enables verification before dispatching personnel.
FAQs
Question | Answer |
---|---|
What accuracy can I expect for temperature measurement? | The device supports temperature measurement from -20 °C to 550 °C and the accuracy is ±2 °C or ±2%. |
Can it detect fire or smoke before flames are visible? | Yes, it includes fire detection algorithms and smoke detection. Thermal imaging helps detect hotspots early; the camera’s sensors + alerts can help trigger actions before flames become visible. |
How good is low-light optical performance? | Quite good: very low lux requirements (~0.05 colour, ~0.01 B/W) with the optical module; plus WDR of 120 dB helps with contrast in challenging lighting. |
What is the zoom capability and field of view? | Optical zoom is 32×; wide field of view of ~58.8° × 34.4° (optical, at wide end) down to narrow view ~2.18° × 1.2°. Thermal zoom is digital (×2, 4, 8). |
How far can it see / detect objects reliably? | The VCA (vehicle/people classification) detection ranges are approx. 80 m for people, 240 m for vehicles under good conditions. |
Does it work in harsh, outdoor environments? | Yes. Rated for a wide temperature range (~-40 °C to +70 °C), IP66, has surge and lightning protection, weather-proofing. |
What kinds of alarms / intelligent functions are included? | Perimeter protection (line crossing, intrusion etc.), temperature exception alarm, fire detection, smoke detection, smart tracking and linking between thermal/optical views. |
Can the camera stay on its preset or patrol route if power cycles? | Yes; it supports features like power-off memory, which allows returning to presets / patrol routes after interruptions. |
