Dahua DH-SD42C212T-HN 2MP Camera The Dahua DH-SD42C212T-HN 2MP Camera is a professional 12x Starlight PTZ network camera designed for reliable surveillance and detailed monitoring. It features a 1/2.8-inch 2MP STARVIS CMOS sensor that delivers Full HD 1920×1080 video at up to 25/30fps, while its 12x optical zoom allows users to capture clear details across large areas. With Starlight technology, 120dB WDR, intelligent video surveillance functions, H.265+ compression, and triple-stream encoding, it provides excellent performance in challenging lighting conditions. The camera supports smooth 360° endless pan and wide tilt movement, PoE+ connectivity, ONVIF compatibility, and IK10 vandal resistance, making it suitable for demanding indoor and outdoor security applications. Starlight Technology For challenging low-light applications, Dahua’s Starlight Ultra-low Light Technology offers best-in-class light sensitivity, capturing color details in low light down to 0.005 lux. The camera uses a set of optical features to balance light throughout the scene, resulting in clear images in dark environments. Wide Dynamic Range The camera achieves vivid images, even in the most intense contrast lighting conditions, using industry-leading wide dynamic range (WDR) technology. For applications with both bright and low lighting conditions that change quickly, True WDR (120 dB) optimizes both the bright and dark areas of a scene at the same time to provide usable video. Smart H.265+ Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network. Smart H.265+ technology reduces bit rate and storage requirements by up to 70% when compared to standard H.265 video compression. PFA Technology PFA technology has innovatively introduced new methods of judgment to ensure the accuracy and predictability of the direction of subject distance adjustment. The result is a set of advanced focusing algorithms. PFA ensures clarity of the image throughout the process of zooming and shortens focus time. The realization of PFA technology substantially improves user experience and increases product value. Environmental Dahua cameras operate in extreme temperature environments, rated for use in temperatures from -30 °C to +60 °C (-22 °F to +140 °F) with 90% humidity. The camera complies with the IK10 Vandal Resistance impact rating. Protection The camera allows for ±10% input voltage tolerance, suitable for the unstable conditions for outdoor applications. Its 2KV lightning rating provides effective protection for both the camera and its structure against lightning.
