Product Description

Product Specifications

Dahua DHI-TPC-BF2241-B7F8-DW-S2 - Thermal Imaging Hybrid Bullet Camera

The Dahua DHI-TPC-BF2241-B7F8-DW-S2 is a thermal imaging hybrid bullet IP camera with thermal and visible channels. Dahua's ordering information lists this model with a 7 mm thermal lens and an 8 mm visible lens. The visible channel is 4 MP, and dual image fusion combines thermal and visible video. AI functions include perimeter protection, heat detection, smoking detection and call detection, and a built-in white light and speaker give light and sound alarms. Dahua lists the family on its website as TPC-BF2241, without the DHI- prefix.

Also listed as TPC-BF2241-B7F8-DW-S2.

Key features

Thermal and visible dual channels for 7x24h monitoring.
Vanadium oxide uncooled focal plane detector with 256 x 192 effective pixels. This model has a 7 mm thermal lens (field of view H 24°, V 18°) and an 8 mm visible lens (H 33.4°, V 25°).
4 MP progressive scan CMOS visible channel, up to 2336 x 1752.
Dual image fusion of visible and thermal images, with 18 color palettes.
AI functions: IVS perimeter protection (tripwire and intrusion), human/vehicle classification, heat detection, smoking detection and call detection.
Built-in white light and speaker that produce light and sound alarms to deter intruders.
Built-in IR LED, so the visible channel also works as an infrared camera at 0 lux, with an illumination distance of 50 m on the 8 mm lens.
PoE (802.3af) or 12 VDC ±20% power supply, and IP67 rated.

Common questions

What is the difference between the B7F8 and B3F4 models?

Dahua's ordering information lists the DHI-TPC-BF2241-B7F8-DW-S2 with a 7 mm thermal and 8 mm visible lens, and the B3F4 with a 3.5 mm thermal and 4 mm visible lens. The 7 mm lens has the narrower view and the longer distances, for example a heat detection distance of 86 m against 45 m.

What does dual image fusion mean on this camera?

Dahua lists dual image fusion of the visible and thermal images, with fusion modes of warm color, cold color and fuse with iron oxide red, plus a PIP mode. Intelligence turns off automatically when PIP is on.

Which AI functions does it have?

Dahua lists IVS perimeter protection with tripwire and intrusion, human/vehicle classification, smoking detection, call detection, heat detection and cold/hot spot trace.

How does the camera deter intruders?

It has a built-in white light and speaker that produce light and sound alarms to deter intruders.

How is it powered?

12 VDC ±20% or PoE (802.3af). Basic power consumption is under 4.5 W on 12 VDC or 4.9 W on PoE.

Is it suitable for outdoor use?

Yes. It is IP67 rated, which makes it a waterproof camera for outdoor use, with an operating temperature of -30 °C to +60 °C.
