Dahua TPC-BF1241-T-V1 is a thermal network mini hybrid bullet camera engineered to deliver reliable 7×24h monitoring by combining a thermal detection channel with a full-color visible imaging channel in one compact housing. This dual-sensor approach allows the camera to detect heat signatures in complete darkness while still capturing clear visible footage for identification purposes.
At the core of the Dahua TPC-BF1241-T-V1 is a vanadium oxide uncooled thermal detector offering 256 × 192 resolution, paired with a 4MP visible sensor delivering 2688 × 1520 resolution. With lens options of 3.5 mm, 7 mm, and 10 mm on the thermal side, the camera can be tailored to different coverage distances, achieving heat detection ranges of up to 123 meters depending on the focal length selected.
Smart detection features set the Dahua TPC-BF1241-T-V1 apart from standard bullet cameras. It supports tripwire and intrusion detection with entry, exit, and appear rules for both human and vehicle targets, alongside advanced capabilities such as fire detection and alarm, cold and hot spot tracing, and human/vehicle classification. Unique additions like smoking detection and call detection make it especially suited for workplace safety and compliance monitoring.
Temperature measurement functionality extends the Dahua TPC-BF1241-T-V1’s utility well beyond basic surveillance. The camera supports spot, line, and area temperature modes with up to 21 rules running simultaneously, plus a wide operating range spanning -20°C to +650°C in high temperature mode, making it suitable for fire prevention and equipment monitoring applications.
Built to withstand demanding environments, the Dahua TPC-BF1241-T-V1 features an IP67 and IK10-rated housing, operating reliably from -40°C to +65°C. It includes a built-in white light and audio alarm for active deterrence, along with wide voltage support of 12–24VDC and PoE compatibility for flexible installation.
Whether deployed for perimeter security, fire risk monitoring, or workplace safety compliance, the Dahua TPC-BF1241-T-V1 combines thermal imaging precision, intelligent analytics, and rugged construction into a single compact solution built for continuous outdoor operation.
