Name: 4MP WizSense Thermal Network Bullet Kamera
Brand: Dahua
SKU: TPC-BF1241-TB3F4

Combines thermal and visible imaging in one body, measures temperature and triggers heat alarms.

Built for outdoor use, this bullet camera brings a vanadium oxide thermal detector and a 4 MP visible sensor together in one body. It measures temperature from 0 °C to +550 °C, triggers heat alarms and separates people from vehicles on the device itself.

Key features

256 × 192pixels

Vanadium oxide detector

The uncooled focal plane thermal detector turns heat differences straight into an image.

4MP

Visible channel

A 1/2.7" CMOS sensor delivers color video at 2336 × 1752.

550°C

Temperature measurement

High temperature mode covers 0 °C to +550 °C, while low mode starts at –20 °C.

30m

Infrared illumination

The visible channel lights the scene up to 30 meters in complete darkness.

12rules

Simultaneous measurement

It runs spot, line and area rules at the same time.

256GB

Edge storage

A micro SD card keeps the recording on the camera itself.

IN DAILY USE

AI filteringIt runs human and vehicle classification, tripwire and intrusion rules, and also detects smoking and phone calls.

Dual imagingIt records the thermal and visible channels at the same time and merges both into a single frame in fusion mode.

Setup and managementIt supports remote auxiliary management and follows the ONVIF, CGI and Dahua SDK interfaces.

Usage AreaOutdoor perimeter security·Early warning from heat sources·Vehicle and pedestrian crossings·Areas under a smoking ban

Temperature measurement accuracy stays within ±2 °C or 2% across the –20 °C to +50 °C operating range.
