Powered by a Dual-core Intel processor and 4GB DDR3 memory, the new series delivers quality performance with up to 250 Mbps throughput to ensure steady recording of multiple megapixel IP cameras. Moreover, the HDMI output and hardware decoder provide the ability to deliver up to 200fps full HD local display.

The VS-4100U-RP Pro+ series supports up to 16Tb raw storage capacity to accommodate high quality H.264, MPEG-4, M-JPEG, and MxPEG video recording. "The VS-4100U-RP Pro+ series satisfy the requirements of SMB users who require high performance network video recorders coupled with excellent reliability and features," said Amily Fang, product manager of QNAP Security. "The VS-4100U-RP Pro+ series delivers quality performance coupled with abundant features for small to medium-scale surveillance tasks."

Featuring the Viostor NVR firmware v4.1.0, the VS-4100U-RP Pro+ series supports smart recording, storage expansion, and multi-stream function. The smart recording effectively avoids constant storage consumption at all times, but achieves greater storage efficiency and boosts recording quality when alarm events happen. By installing the Storageexpansion app (QPKG) on the Turbo NAS, administrators can connect the VS-4100U-RP Pro+ series with the Turbo NAS via network to flexibly enlarge the total storage capacity of Viostor NVR. The multi-stream support enables administrators to flexibly define multiple video streams (supported by specific camera models) according to bandwidth resources and number of live-view channels.

The VS-4100U-RP Pro+ series provide professional features for business environments, including fisheye dewarping function, multi-server monitoring, advanced event management, and more. The fisheye dewarping function is supported for specific fisheye cameras and cameras with panomorph lens on handling remote monitoring, playback and local display. Multi-server monitoring enables users to connect multiple Viostor NVRs and monitor up to 128 IP cameras with one browser on remote computers. Advanced event management enables administrators to set 5 types of alarm event, and the system will respond with assigned event actions when an event is triggered, alerting administrators immediately.

The VS-4100U-RP Pro+ series supports Windows and Mac platforms with QNAP’s surveillance client software for Windows and for Mac, and the Vmobile surveillance app for iOS, Android and Windows Mobile 6.1 to 6.5 devices. Users can manage the Viostor NVR via the web-based administration interface using Google Chrome, Microsoft Internet Explorer or Mozilla Firefox browsers, or monitor linked IP cameras by mobile devices anytime and anywhere on the go.

The Viostor NVR is now now shipping and compatible with over 2,100 IP camera models of various popular brands, offering businesses high flexibility in deploying an ideal surveillance solution.
