Hikvision 4MP Covert Network Camera DS-2CD2D45G2/S-U(2.8mm)

Hikvision 4MP Covert Network Camera DS-2CD2D45G2/S-U(2.8mm) The Hikvision DS-2CD2D45G2/S-U(2.8mm) is a compact 4MP covert network camera designed for discreet indoor video surveillance. Its 1/3-inch Progressive Scan CMOS sensor captures detailed video at up to 2688 × 1520 resolution, while the 2.8mm fixed lens provides a wide 90.5° horizontal viewing angle. AcuSense intelligent analytics, face capture, a built-in microphone and efficient H.265+ compression make it suitable for professional applications where a small, unobtrusive camera is required. Key Features 4MP compact covert network camera. 1/3-inch Progressive Scan CMOS image sensor. Maximum resolution of 2688 × 1520. Up to 30fps at full 4MP resolution. 2.8mm fixed F2.0 lens. Wide 90.5° horizontal field of view. AcuSense intelligent analytics. Face Capture support. Built-in microphone for audio capture. Triple-stream video architecture. H.265+, H.265, H.264+, H.264 and MJPEG compression. 120dB Wide Dynamic Range. 4MP High-Resolution Imaging The DS-2CD2D45G2/S-U uses a 1/3-inch Progressive Scan CMOS image sensor to capture video at resolutions up to 2688 × 1520. It supports up to 25fps at full resolution in 50Hz environments and up to 30fps in 60Hz environments, providing detailed and fluid surveillance footage. Wide-Angle 2.8mm Fixed Lens The requested 2.8mm configuration uses an F2.0 fixed-aperture lens with a 90.5° horizontal, 46.2° vertical and 110° diagonal field of view. This wide viewing angle is well suited to monitoring rooms, counters, entrances and other areas where broad scene coverage is required from a compact camera. AcuSense Intelligent Analytics Hikvision AcuSense technology provides intelligent video-analysis capabilities designed to improve the usefulness of surveillance events. The camera family also supports Face Capture functionality for applications requiring intelligent detection and analysis. Integrated Audio Capture A built-in microphone enables the camera to capture mono audio alongside video without requiring a separate microphone at the camera position. Environmental noise filtering is supported to help improve captured audio in suitable installations. Efficient Video Compression The main video stream supports H.265+, H.265, H.264+ and H.264 compression, helping reduce network bandwidth and storage requirements. The camera also supports a sub-stream and third stream, allowing different resolutions and compression settings to be configured for recording, monitoring and remote viewing. Compact Covert Surveillance The compact special-series design makes the DS-2CD2D45G2/S-U suitable for discreet indoor surveillance where a conventional dome or bullet camera may be too prominent. Its combination of 4MP imaging, integrated audio and intelligent analytics provides professional surveillance functionality in a small camera platform.
