Dahua DHI-TPC-BF2241-B3F4-DW-S2 - Thermal Imaging Hybrid Bullet IP CCTV Camera

Dahua DHI-TPC-BF2241-B3F4-DW-S2 - Thermal Imaging Hybrid Bullet IP CCTV Camera

The Dahua DHI-TPC-BF2241-B3F4-DW-S2 is a thermal imaging hybrid bullet IP CCTV camera from Dahua's Lite Series. It has a thermal channel (256 x 192 vanadium oxide uncooled detector, 3.5 mm lens) and a visible channel (4MP CMOS, 4 mm lens), with dual image fusion of the visible and thermal images. The thermal channel detects heat rather than visible light. Dahua positions it for short distance monitoring such as perimeter protection and heat monitoring in small and medium scenes. Zenith supplies the camera; we do not provide installation services.

Also listed as TPC-BF2241-B3F4-DW-S2.

Dahua's datasheet covers the DHI-TPC-BF2241 family and its ordering table lists this model (B3F4) as thermal 3.5 mm and visible 4 mm.

Technical specification

DRI distances (thermal channel, 3.5 mm lens)

Dahua standard theoretical calculation, for reference only. Real distances depend on atmospheric conditions, target size and the installation site.

Works with

Dahua lists these as optional accessories: the PFA121 junction box for wall mounting, used with the PFA150 pole mount bracket or the PFA151 corner mount bracket.

• PFA121 waterproof junction box
• PFA150 pole mount bracket
• DH-PFA151 corner mount bracket

Common questions

Which lenses does this camera have?

This B3F4 model has a fixed 3.5 mm thermal lens (H 50.6°, V 37.8°) and a fixed 4 mm visible lens (H 71.2°, V 52°). For a longer reach, see the DHI-TPC-BF2241-B7F8-DW-S2, the 7 mm thermal and 8 mm visible lens version.

Can this camera see in total darkness?

The thermal channel detects heat rather than visible light. A built-in IR LED (up to 35 m with the 4 mm lens) also supports the visible channel at night, alongside the thermal channel.

Does it record without an NVR?

It has a Micro SD card slot for cards up to 256 GB, so it can store footage locally as well as being run from a PoE NVR.

What AI functions does it have?

Dahua lists tripwire and intrusion detection, human and vehicle classification, heat detection, smoking detection and call detection.

How is it powered?

By 12 VDC ±20% or PoE (802.3af). Basic power consumption is under 4.5 W on 12 VDC (4.9 W on PoE) and the maximum is under 11.8 W (12.2 W on PoE).

Is the camera suitable for outdoor use?

Yes, it works as an outdoor camera and outdoor security camera, with an IP67 ingress protection rating that also makes it a waterproof camera, and an operating range of -30 °C to +60 °C.

How far can the thermal channel detect?

With the 3.5 mm lens Dahua lists a heat detection distance of 45 m, and a perimeter protection distance of 72.5 m for a vehicle and 24.5 m for a human. See the DRI table above for the detection, recognition and identification figures.
