Vivotek NR9581 32 Channel H.265 Network Video Recorder

VIVOTEK's NR9581 is a full-featured high-performance H.265 NVR. Equipped with a 2U 32-CH 8 Bay Rackmount network appliance, standard RAID capability and H.265 video codec, the total storage capacity of the NVR also endows the NR9581 with scalability and flexibility, making it perfect for large-scale transport or industrial applications as well as public spaces such as campuses.

The NR9581's 8 hard-drive bay design provides for a storage capacity of up to 48TBs, offering greater than 30% ~ 50% more recording capacity than systems employing H.264 compression. This advance affords users larger storage space for longer durations of video recording. The RAID 0/1/5/6/10 configuration provides further data security in the rare event of a hard drive failure. Further, equipping the NR9581 with a DOM system has resulted in reliability and stability beyond the reach of other NVRs. Meanwhile, the NR9581 supports VIVOTEK's fisheye network camera “Fisheye Dewarp″ function, which provides multiple de-warping modes in live view and playback, ensuring the correct angle of video view and detailed information for flexible usage. This ingenious NVR is also equipped to carry out remote management with a full range of the server/client structures and thus constitutes a robust system for diverse applications.

Moreover, the NR9581 features well-built ONVIF compliance and scalable configuration, with VAST CMS empowering users to set up and manage advanced IP surveillance systems with ease. The NR9581 also supports both remote and mobile access via iViewer app, for both iOS and Android handheld devices. The NR9581 represents a great advance in the field, providing users an open, intelligent and seamless NVR to meet market demands.
