The NK8BA4 2MP Box Network Camera from Dahua Technology features a 1/1.7" progressive scan Sony STARVIS CMOS sensor. It uses 4K Technology to deliver four times the resolution of standard HDTV 1080p cameras and offers superior picture quality and image details. It has an electronic Pan/Tilt/Zoom functionality to scan a portion of the scene and zooms in for a detailed view. It uses the Smart H.265+ video compression standard to improve encoding efficiency while preserving high-quality video. The camera features built-in business intelligence algorithms, auto back focus, PoE, and a microSD card slot. It supports H.265 and H.264 dual codec compression formats with triple-stream encoding. The camera uses an IVS analytic algorithm that delivers intelligent functions to monitor a scene for tripwire violations, intrusion detection, and abandoned or missing objects.
