Dahua TPC-BF5401 35mm Fixed-focal Thermal Network Bullet Camera
The Dahua TPC-BF5401 is a thermal network bullet camera designed for medium- to long-distance perimeter monitoring and heat detection in demanding outdoor environments. This 35 mm version combines a 400 × 300 vanadium oxide uncooled detector with a focused 11.1° horizontal field of view, helping security teams monitor defined areas in darkness and challenging lighting conditions.
Thermal Monitoring for Challenging Environments
Rather than relying on visible light, the camera detects thermal energy within the scene. Its 35 mK thermal sensitivity and digital detail enhancement help reveal temperature differences, while a choice of 18 colour palettes allows operators to adapt the thermal display to the monitoring task.
Intelligent Perimeter Protection
Built-in analytics support tripwire and intrusion rules, together with human and vehicle classification. Heat detection and cold/hot spot tracing provide additional tools for monitoring unusual thermal activity. Detection performance depends on the target, weather, installation and site conditions, so Dahua's published distances should be treated as planning references rather than guaranteed operating ranges.
Flexible Network and System Integration
The camera supports H.265 and H.264 compression, ONVIF interoperability and local recording to an optional microSD card of up to 512 GB. A 10/100 Mbps Ethernet port, PoE, ePoE and 12 V DC power options simplify integration, while audio, alarm, RS-485 and CVBS connections support wider security-system requirements.
Key Features:
- 400 × 300 vanadium oxide uncooled thermal detector for continuous thermal monitoring.
- 35 mm fixed-focal F1.0 lens with an 11.1° horizontal and 8.3° vertical field of view.
- 35 mK thermal sensitivity helps distinguish small temperature differences in a scene.
- Heat detection, cold/hot spot tracing, tripwire and intrusion analytics support proactive monitoring.
- Human and vehicle classification helps operators focus on relevant perimeter events.
- H.265, H.264 and MJPEG video compression, with ONVIF, CGI and Dahua SDK interoperability.
- IP67-rated metal housing, PoE/ePoE support and operation from —30 °C to +70 °C suit demanding installations.
35 mm Monitoring Distances
The figures below are Dahua's reference distances for the 35 mm lens. Detection indicates that an object is visible; recognition supports classification into a general category; and identification provides sufficient image coverage for more specific classification. Actual performance varies with the target, atmospheric conditions and installation.
| Target | Detection | Recognition | Identification |
| Human | 1,029 m | 264 m | 132 m |
| Vehicle | 3,167 m | 776 m | 392 m |
Reference distances are calculated under Dahua's stated test criteria and are estimates only. Site conditions, weather, target size and installation can affect real-world performance.
