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, effective night monitoring on the Distance can be performed up to 30 metres, and the Function automatic switching between the day and night mode guarantees continuous observation.
By Camera it has a permanent Lens of 2.8 mm or 3.6 mm focal length, offering a wide Field of View ( 107° horizontal and 56° vertically respectively for 2.8 mm and 88° horizontal and 44° vertically for 3.6 mm).
Advanced Image Processing Functions, such as WDR 120 dB, 3D NR and Wide Dynamic Range, eliminate noise and provide realistic color reproduction even in difficult lighting conditions.
For Camera to support H265+/H264+ compression, allowing a significant reduction in bandwidth and disk space consumption without losing image quality.
Additionally, Functions such as Smart Tracking (IVS), regions of interest (ROI) and privacy masks allow precise adjustment of monitoring to individual needs.
For Camera to be weather resistant (IP67) and can operate at temperatures from -40°C to +60°C, making it ideal for external applications.
PoE Power Supply (802.3af) simplifies installation and low Power consumption (up to 5.5 W) minimizes operating costs.
Dahua IPC-HDW2231TM-AS-0280B-S2 is a comprehensive solution for monitoring systems requiring reliability, high image quality and advanced analytical functions.
