DAHUA TPC-BF1241-B3F4-DW-S8 termálna kupolová kamera, 256x192 termálna & 4MP viditeľná, 3.5mm/4mm, IP67, PoE

For perimeter security and early fire detection in challenging conditions, the DAHUA TPC-BF1241-B3F4-DW-S8 combines a 256x192 uncooled thermal sensor with a 4MP visible-light camera in a single rugged bullet housing. Unlike conventional CCTV, it sees heat signatures through darkness, smoke, and light fog, while the visible channel captures evidentiary detail. Dual-spectrum fusion and smart analytics make it a proactive tool for industrial, commercial, and critical infrastructure sites.

Highlights

• Dual-sensor design: 256x192 thermal (3.5mm lens, 50.6°x37.8° FOV) and 4MP visible (4mm lens, 84°x45° FOV).
• Temperature measurement from -20°C to +150°C with ±2°C or ±2% accuracy; supports fire detection and cold/hot spot tracking.
• IP67 weatherproof and IK10 vandal-resistant metal housing for outdoor use in extreme conditions.
• Smart video analytics: intrusion detection, tripwire, and fire detection with alarm I/O (2 in / 2 out).
• Flexible power: 12V DC or PoE (802.3af), with built-in microphone and microSD slot (up to 256GB).

In daily use

Mount the camera at a perimeter gate, loading dock, or transformer yard. The thermal channel immediately flags a person or vehicle by heat signature, even in total darkness, while the visible channel zooms in for identification. Configure tripwire rules to trigger an alarm output when someone crosses a boundary, or set temperature thresholds to alert on overheating equipment. Live view can be toggled between thermal, visible, or fusion modes for optimal situational awareness. The built-in microphone adds audio context, and recordings can be stored locally on a microSD card or streamed to an NVR.
