Dahua DHI-TPC-BF2241-B3F4-DW-S2 — Value Thermal Hybrid Bullet Camera
The Dahua DHI-TPC-BF2241-B3F4-DW-S2 is a value thermal hybrid bullet camera with a fixed 3.5mm lens on its visible channel, pairing a vanadium oxide uncooled thermal detector with a 4MP CMOS image and built-in Micro SD storage.
Who is it for?
This camera suits trade customers and installers specifying budget-conscious perimeter and boundary detection where conventional night vision falls short — thermal imaging works through total darkness, smoke and light fog. It's a component for compounds, yards, warehouses and building perimeters where early detection and active deterrence matter, with onboard Micro SD storage useful for standalone or edge recording. Zenith supplies the camera as part of a wider system; we do not provide installation services.
