Hikvision 4MP Covert Network Camera 2.8

The Hikvision DS-2CD2D45G2/S-U 4MP Covert Network Camera is designed for discreet, professional indoor surveillance where compact size and unobtrusive monitoring are important. Equipped with a 4MP Progressive Scan CMOS sensor, it captures detailed video at up to 2688 × 1520 resolution, helping provide clear surveillance footage for business and commercial environments.

The fixed 2.8mm F2.0 lens offers a wide 90.5° horizontal field of view, making it suitable for monitoring entrances, counters, offices, rooms and other indoor areas. With 120dB Wide Dynamic Range (WDR), the camera helps manage challenging lighting conditions with bright and dark areas in the same scene.

Featuring Hikvision AcuSense intelligent analytics, Face Capture support and a built-in microphone, this camera combines video monitoring, intelligent surveillance features and audio capture in a compact covert camera design. H.265+ compression helps reduce bandwidth and storage requirements, making it a practical option for professional IP surveillance systems.
