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, it works effectively at night, with a range of up to 30 meters, making it an excellent choice for 24-hour surveillance.
Functions such as WDR (120 dB) and 3D NR guarantee high image quality even in difficult lighting conditions, eliminating noise and distortion.
For Camera to support H265/H264 compression, allowing saving bandwidth and disk space without losing image quality.
Additionally, Technology Smart Codec (Smart H265+/Smart H264+) optimizes the flow rate depending on Scenes, which increases monitoring efficiency.
IPC-HDW2231T-AS-0280B-S2 has a fixed focal length of 2.8 mm or 3.6 mm, offering a wide Field of View ( 107°/56° and 88°/44° in height/pierce, respectively).
For Camera to be equipped with Lens with M12 mount, making installation easier.
Functions such as IVS (intrusion detection and Areas prohibited), the region of interest (ROI) and intelligent Lighting increase safety levels, allowing precise monitoring of selected areas.
For Camera to be weather resistant (IP67) and to operate in a wide temperature range (-40°C to +60°C), making it ideal for outdoor applications.
It also supports advanced Network Functions such as ONVIF, HTTPS, 802.1x and Encryption data, which provides Transmission Security.
Dahua IPC-HDW2231T-AS-0280B-S2 is a comprehensive solution for monitoring systems, combining high image quality with advanced security features.
