The ND8321 is a compact Linux embedded 8-channel standalone desktop NVR designed for any small-scale video surveillance installation. ND8321 achieves non-screwdriver installation, and facilitates "one button setup" with its plug and play and auto setup functionality. Supporting Full HD HDMI local video output, users can control the GUI OSD interface via mouse and keyboard, eliminating the need for a separate PC to view video or to playback from the NVR. The new local dislpay design - Auto Adaptive Stream will dynamically modify Stream 2 resolution of a camera to best fit the display resolution according to the layout type, performing an efficient display. Fisheye dewarp is also designed in ND8321. ND8321 supports software dewarp of VIVOTEK fisheye cameras, allowing seamless display in a fisheye surveillance scenario. Together with VAST CMS and ST7501 VMS, users can set up an easy-to-use IP surveillance system with ease. VIVOTEK also provides the mobile application, iViewer, for both iOS and Android handheld devices, enabling users to monitor live video anytime, anywhere.
