The Hikvision DS-2CD2743G0-IZS (2.8–12 mm) is a high-performance 4 megapixel outdoor motorized varifocal dome network camera engineered to provide flexible and detailed surveillance for commercial, residential, and industrial environments. It features a 1/3″ progressive scan CMOS sensor that captures crisp video at 2688 × 1520 resolution, delivering clear imagery for monitoring entrances, perimeters, parking areas, and high-traffic zones. The motorized varifocal lens (2.8–12 mm) allows remote adjustment of the viewing angle and zoom to tailor coverage without manual lens changes, while 120 dB WDR (wide dynamic range) enhances contrast performance in challenging lighting conditions like strong backlight or shadows. With efficient H.265+/H.265 compression, the camera optimizes bandwidth and storage use without sacrificing video quality. Built-in IR illumination supports reliable night vision up to approximately 40 m, and the rugged weather-resistant housing (IP67) plus vandal-resistant design (IK10) ensures dependable all-weather operation. The camera also supports multiple video streams and intelligent functions such as behavior analysis and basic detection, enhancing monitoring efficiency for modern networked surveillance systems.
