Dahua NVR4208-8P-4KS2 NVR comes with Smart H.265+/H.265/Smart H.264+/H.264, Max 200Mbps Incoming Bandwidth, Up to 8MP Resolution for Preview and Playback, Up to 2ch@4K/8ch@1080P decoding, and HDMI/VGA simultaneous video output. This NVR also supports IPC UPnP, 8PoE ports. Here, the Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, which is 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
