Dahua IPC-HFW2231S-S-0280B-S2

SKU: 6923172520166

Equipped with a Transducter 1/2.8" CMOS, it offers a Resolution 2MP (1920x1080), providing a clear and detailed Picture.

Thanks to Lite IR By Camera technology works effectively even in total darkness, with a range of up to 30 meters.

Functions such as WDR (120 dB), BLC and HLC guarantee excellent image quality in different lighting conditions.

IPC-HFW2231S-S-0280B-S2(6923172520166)_image_2

For Camera to support H265, H264 and MJPEG compression, allowing you to optimize bandwidth and memory usage.

Additionally, Functions IVS (intrument detection and Areas prohibited) and the Region of Interest (ROI) allow intelligent monitoring of selected areas.

For Camera to be weather-resistant (IP67) and to operate in a wide temperature range (-40°C to +60°C).

Powered by PoE or 12V DC, it is characterized by low energy consumption.

Ideal for applications in safety systems, urban monitoring or industrial property protection.
