By purchasing the Dahua DH-IPC-HDW2431TP-AS-S2 (2.8 mm) camera from the Dahua Lite brand, you get a reliable solution for outdoor or indoor video surveillance with high resolution and advanced image processing functions. This IP camera provides high-quality detail thanks to its 4 MP sensor and WDR 120dB support, making it effective in challenging lighting conditions.

Key Advantages

• 4 MP resolution (2560x1440) for a clear image;
• 1/3" Progressive CMOS sensor for high-quality detail capture;
• Support for modern H.265, H.264, and MJPEG codecs for economical video storage;
• Ultra-sensitivity of 0.008 Lux at F1.6 aperture for operation in low-light conditions;
• Fixed f=2.8 mm lens with a 102° viewing angle for wide coverage of the surveillance area;
• WDR (120dB), 3D-DNR, BLC, HLC, and ROI functions to improve image quality in various scenes;
• IP67 rated housing protection — the camera is adapted to moisture and dust;
• DC 12V (6.6W) power and PoE (802.3af) support for flexible installation;

Function Description and Application

This model is optimal for video surveillance of shops, offices, entrances, and areas around buildings. Thanks to WDR 120dB, the camera corrects high-contrast scenes, preserving detail in both bright and dark areas of the frame. 3D-DNR functions reduce noise in night recordings, BLC and HLC help correct glare from lamps or headlights, and ROI allows highlighting important areas of the frame for prioritized compression and quality preservation.

Technical Specifications

When installing, consider the 102° viewing angle and fixed 2.8 mm focal length — this allows covering fairly wide areas, but if detailed recognition of license plates or faces is needed, installation should be planned with an appropriate distance to the object. PoE connection simplifies cable routing and power supply, and the micro SD card slot provides an option for autonomous recording in case of network connection loss.

This camera combines modern image processing algorithms, high resolution, and a protected housing, making it an attractive choice for complex video surveillance systems and projects with strict image quality requirements.
