Product Overview
Combining a thermal imaging sensor with a 4-megapixel optical module, the Hikvision DS-2TD1228-3/QA is a bi-spectrum network turret camera for fire detection, temperature exception monitoring, and perimeter analysis. The thermal channel uses a 256 × 192 VOx uncooled sensor with a 12 μm pixel pitch and a 3.6 mm lens providing a 50.0° × 37.3° field of view. The optical channel captures 2688 × 1520 footage through a 4.3 mm lens, with 120 dB WDR and IR illumination up to 15 m. The camera supports up to 21 temperature measurement rules across a range of −20°C to 150°C, with ±8°C accuracy. Other listed functions include smoking detection and a sun-reflection filter. Its IP67-rated housing and −40°C to 65°C operating range suit outdoor and industrial installations.
Key Capabilities
Fire and Smoking Detection
Hikvision lists fire detection and smoking detection among the camera’s functions. Configure alarm rules and test them against the conditions at the installation site.
Temperature Measurement Across 21 Rules
Configure up to 21 temperature measurement rules: 10 points, 10 areas, and 1 line. The specified measurement range is −20°C to 150°C, with ±8°C accuracy. Temperature exception alarms can be configured against selected thresholds.
Bi-spectrum Fusion and Picture-in-Picture
Thermal and optical images can be viewed together using bi-spectrum image fusion or picture-in-picture display, helping operators relate a thermal event to the visible scene.
Sun-Reflection Filter
The listed sun-reflection filter helps manage a potential source of nuisance alarms in locations with reflective surfaces. Test detection performance at the intended mounting position.
Perimeter Video Analysis
Supports up to 8 video analysis rules across line crossing, intrusion, region entrance, and region exiting. Set detection areas and thresholds for the scene being monitored.
Audible and Visual Alarms
The built-in white light alarm has a listed range of up to 30 m and adjustable flashing frequency. Audible alerts can be configured for video analysis and temperature exception events.
Best For
- Warehouse and Storage Facilities: Monitor selected areas for fire-related events and temperature exceptions, subject to site-specific placement and alarm configuration.
- Industrial Yards and Outdoor Perimeters: Combine thermal perimeter analysis with optical verification in an IP67-rated outdoor housing.
- Electrical and Plant Rooms: Set point and area temperature rules for equipment within the camera’s measurement range and effective measurement distance.
- Waste and Recycling Sites: Use thermal fire detection to monitor selected risk areas, with coverage and alert settings designed for the site.
Why Choose the DS-2TD1228-3/QA
The DS-2TD1228-3/QA places a 256 × 192 thermal sensor and a 4-megapixel optical sensor in one turret camera. It supports fire detection, temperature exception alerts, perimeter analysis, and visual verification from the same mounting position. Its 21 configurable temperature rules provide flexibility for monitoring defined points and areas within the specified −20°C to 150°C measurement range. Select the mounting location and lens coverage against the size and distance of the targets you need to monitor.
Buyer Decision Tips
Thermal Resolution vs. Coverage Area: The 256 × 192 thermal sensor and 3.6 mm lens provide a 50.0° × 37.3° thermal field of view. Check the size of the target at the intended mounting distance. Detecting a person and measuring the temperature of a small component are different tasks with different practical ranges.
Integration and Storage Planning: Confirm the required recording method, alarm connections, and event support with your NVR or VMS before installation. Third-party integration should be tested for the specific temperature and video analysis events you intend to use.

Ideal Use Cases
Waste and Recycling Facilities
Position the thermal channel to monitor defined areas for fire-related events and temperature exceptions. Verify detection performance against the size and distance of likely hot spots.
Warehouse Loading Docks
Use thermal perimeter rules and optical footage to review activity around loading bays. Configure alarm zones to account for normal vehicle and equipment movements.
Electrical Switchrooms
Configure point and area temperature rules for visible equipment within the specified measurement range. Check target size and distance before relying on readings from individual components.
Outdoor Industrial Perimeters
Combine thermal detection with 4MP optical verification in an IP67-rated housing designed to operate from −40°C to 65°C.
Solar Farms and Open-Air Plant Sites
The listed sun-reflection filter may help manage reflected-light nuisance alarms. Assess actual performance against the site’s surfaces, viewing angle, and daily sun exposure.
Choosing the Right Model
- Choose this model if: You need thermal fire detection, temperature exception monitoring up to 150°C, perimeter analysis, and 4MP optical verification in one turret camera.
- Choose a different model if: You need to measure temperatures above 150°C or require better stated measurement accuracy than ±8°C. Check the exact alternative model’s datasheet before ordering.
- Choose a different model if: Your required target size, distance, or field of view falls outside what the 256 × 192 sensor and 3.6 mm thermal lens can cover effectively.
FAQs
- What is the difference between the thermal and optical channels?
The 256 × 192 thermal channel detects thermal information for configured monitoring and alarms. The 4MP optical channel records visible detail, with IR illumination up to 15 m. The channels can also be viewed using fusion or picture-in-picture display.
- Can this camera be installed outdoors?
The camera is IP67 rated and has a specified operating temperature of −40°C to 65°C. Select suitable cabling, mounting, weather sealing, and surge protection for the installation.
- Does this model have a forklift alarm filter?
A forklift alarm filter is not listed in the referenced DS-2TD1228-3/QA datasheet. Account for normal forklift movements when designing and testing alarm zones.
- What temperature range can the DS-2TD1228-3/QA measure?
Its specified range is −20°C to 150°C with ±8°C accuracy. It supports up to 21 temperature measurement rules: 10 points, 10 areas, and 1 line.
- Does it support PoE?
Yes. It supports 802.3af PoE, class 3, with a listed maximum PoE consumption of 6.5 W. A 12 VDC power option is also specified.
- Can alarms be integrated with an NVR or another system?
