VIVOTEK’s ND9441 and ND9541H265/H264, Dual LAN, 4xHDD, HDMI/VGA Local Display, RAID, Fisheye Dewarp, VIVOCloud, ONVIF

VIVOTEK’s ND9441 and ND9541 are the brand new H.265 Linux-based embedded standalone NVRs. Equipped for up to 16-CH/32-CH network cameras, the NVRs feature well-built ONVIF compliant and scalable configuration with VAST CMS empowering users to set up and manage advanced IP surveillance systems with ease. Both NVRs also support remote and mobile access, via VIVOCloud and iViewer app, for both iOS and Android handheld devices, providing users an open, flexible and intelligent NVRs for seamless use in small to medium sized video surveillance applications.


With H.265 compression technology and embedded with 4 HDD design providing up to 32TB, the ND9441 and the ND9541 offer greater than 30% more recording capacity than systems employing H.264 compression. This advance gives users larger storage space for longer durations of video recording.


In order to provide uninterrupted service even when the network is temporally disrupted, both NVRs are also equipped with dual Ethernet ports, as well as providing the flexibility to connect with network cameras in network failover situations. In addition, the RAID 0/1/5 configuration provides further data security in the rare event of a hard drive failure.


Further enabling the recording of high-quality and detailed images, the ND9441 and the ND9541 support a maximum network camera resolution of 12-Megapixels. To intelligently manage bandwidth while maintaining this high-quality, the “Auto Adaptive Stream” function will adjust the display resolution automatically for each different layout type.


Moreover, both NVRs support 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. Further, to quickly and intuitively find any target event, the ND9441 and the ND9541 are equipped with “Story-Board Search” function, which provides a glimpse of past recordings over an intuitive timeline.



VIVOCloud App provides users an unbeatable experience for mobile viewing NVR video via a mobile device from anywhere, at any time.

Fisheye Dewarp

VIVOTEK’s NVR offers both LiveView and Playback modes for one fisheye network camera simultaneously. They also provide multiple fisheye de-warp display modes, including 1O, 1P, 1R, 1O3R, 1O8R, allowing users to monitor any angle, or to enjoy precise detailed images for a total surveillance experience.


Story Board Event Search

 To quickly and intuitively find any target event, we provide a glimpse of past recording over an intuitive timeline, allowing users to direct playback and archive their video within 10 seconds.


Finally, the ND9441 and the ND9541 support HDMI and VGA local video output, so users can control the GUI OSD interface via mouse & keyboard, eliminating the need for a separate PC to search video or playback from the NVRs. Moreover, the intuitive and friendly VIVOTEK GUI design gives users an even smoother experience of control than ever before.
