Dahua 4MP WizSense Thermal Network Mini Hybrid Eyeball Camera, DHI-TPC-DF1241-TB2F2-DW-S2

Product SKU: DH-TPC-DF1241 / DH-TPC-DF1241P-D2F2

Product Overview

The Dahua DHI-TPC-DF1241-TB2F2-DW-S2 is a 4MP WizSense thermal network mini hybrid eyeball camera designed for heat monitoring, fire detection, perimeter protection and visual verification. It combines a 256 × 192 thermal detector with a separate 4MP visible-light channel, giving operators heat-based detection in darkness together with conventional video for confirming scene details. Both channels use wide 2mm fixed lenses, making this variant better suited to short-range monitoring of warehouses, plant rooms, recycling areas, car parks, storage facilities and restricted zones than narrow long-distance surveillance. Temperature measurement supports low- and high-temperature modes, configurable spot, line and area rules, and cold or hot spot tracing. The visible channel includes 30m infrared illumination, while image fusion combines thermal and optical information. The IP67 metal housing supports PoE or 12V DC power, microSD storage and external alarm or audio integration.

Key Capabilities

Best For

• Warehouses and Storage Areas: Monitors heat changes, fire risk, people and vehicle movement around stock, racking and loading zones.
• Plant and Electrical Rooms: Applies temperature rules to equipment and defined areas where abnormal heat needs early attention.
• Recycling and Waste Facilities: Helps identify developing hot spots across materials that may heat or ignite without obvious visible warning.
• Restricted and No-Smoking Areas: Uses smoking, call, tripwire and intrusion analytics for specialised event monitoring.
• Dark Perimeters and Car Parks: Combines thermal detection with 4MP visible verification and 30m infrared illumination.

Why Choose the DHI-TPC-DF1241-TB2F2-DW-S2

The DHI-TPC-DF1241-TB2F2-DW-S2 is better suited to heat-sensitive sites than a standard visible-light security camera because it can detect temperature differences and thermal events even when lighting is poor or absent. The second 4MP channel adds recognisable visual context, while image fusion helps operators compare heat information with the physical scene. Its temperature rules, fire detection, hot and cold spot tracing and behaviour analytics make it useful for more than basic perimeter recording. Available through Security Wholesalers, this model should be selected after confirming the required temperature range, target size, measurement distance, field of view and alarm workflow. The 2mm lenses provide broad short-range coverage, so a narrower thermal lens may be more appropriate when the critical target is farther away.

Ideal Use Cases

Choosing the Right Model

• Choose this model if: The project needs broad 2mm thermal coverage, 4MP visible verification and temperature measurement up to +550°C.
• Choose a narrower thermal lens if: The critical target is farther away and broad scene coverage is less important.
• Choose a non-temperature variant if: Heat measurement rules are unnecessary and only thermal detection or perimeter events are required.
• Add external audio or warning devices if: The project requires sound capture, spoken warnings or alarm outputs at the camera location.
• Confirm the recorder first if: Thermal streams, temperature events, image fusion or specialised analytics must be recorded and searched through the back-end system.

FAQs

1. What is the DHI-TPC-DF1241-TB2F2-DW-S2 designed to do?
   The DHI-TPC-DF1241-TB2F2-DW-S2 combines a 256 × 192 thermal channel with a 4MP visible-light channel in one IP eyeball camera. It is designed for heat monitoring, fire detection, perimeter events and visual confirmation in locations such as warehouses, plant rooms, recycling areas, car parks and restricted zones. The camera requires a compatible network recorder or management platform, suitable PoE or 12V DC power and correct thermal commissioning.
2. Is the thermal channel also 4MP?
   No. The 4MP specification applies to the visible-light channel, which records up to 2336 × 1752. The thermal detector has a native resolution of 256 × 192, although the thermal stream can be output at higher display resolutions such as 1280 × 960. Buyers should compare the thermal resolution, lens and detection distances separately from the visible-camera resolution when assessing suitability.
3. What temperature measurement functions are supported?
   The temperature-measuring variant supports low-temperature mode from -20°C to +150°C and high-temperature mode from 0°C to +550°C. Accuracy is listed as the greater of ±2°C or ±2% when the operating temperature is between -20°C and +50°C. Up to 12 temperature rules can operate simultaneously using spot, line or area measurements. Final performance depends on distance, target size, atmosphere, angle and commissioning.
4. How far can the 2mm thermal lens detect people, vehicles and heat sources?
   With the 2mm thermal lens, the listed detection distances are 83 metres for a person and 256 metres for a vehicle. Recognition distances are 21 metres for a person and 63 metres for a vehicle, while identification distances are 11 metres and 32 metres respectively. Heat detection for a 0.2m × 0.2m test target is listed up to 25 metres, subject to environmental and installation conditions.
5. Which intelligent analytics are available?
   The camera supports tripwire and intrusion rules together with heat detection and alarm, cold and hot spot tracing, human and vehicle classification, smoking detection and call detection. These functions allow the thermal and visible channels to be used for both perimeter monitoring and heat-related events. The intended rules, target sizes, detection zones and alarm linkages should be planned during commissioning rather than enabling every function without a site-specific design.
6. Does the camera provide infrared night vision and thermal-visible image fusion?
   Yes. The visible channel includes infrared illumination with a listed range of 30 metres and automatic day and night switching through an ICR filter. The thermal channel operates from emitted heat rather than visible light, allowing monitoring in total darkness. Three fusion modes combine the thermal and visible information to provide additional scene context, while 18 thermal colour palettes help operators display temperature differences in different ways.
7. Does the DHI-TPC-DF1241-TB2F2-DW-S2 have built-in two-way audio?
   No built-in microphone or speaker is confirmed for this S2 variant. The camera provides one audio input and one audio output for compatible external audio equipment, together with one alarm input, one alarm output and one RS-485 pair. External microphones, speakers, amplifiers, warning devices and installation cabling are not stated as included, so the required alarm and audio arrangement must be designed separately.
8. What should I confirm before ordering the DHI-TPC-DF1241-TB2F2-DW-S2?
   Confirm that the temperature-measuring TB2F2 variant is required, then check the 2mm thermal and visible fields of view, detection distances, temperature range, alarm rules, NVR compatibility, microSD requirements, PoE budget, mounting method and environmental exposure. The camera is IP67 but still needs properly sealed connections. Security Wholesalers can review the proposed position and system design to identify likely coverage, measurement, power or integration limitations before installation.
