Intuitive, zero learning
Unlike traditional NVR software that can be hard to use, QVR 5.0 is free from complicated options and terminology, offering an innovative desktop design to compliment smooth working efficiency. The multi-window design allows concurrent multi-tasking and enables administrators to easily switch between tasks to increase their productivity.

Multiple IP camera management comes easy
You can directly configure IP camera recording schedules when needed without leaving the Live-view page, maintain a seamless monitoring so you won't miss any suspicious events. You can also visualize IP camera deployment with the E-map function. Just upload the pictures of the monitored locations, drag and drop the IP camera icons to the right place on the E-map and you can easily monitor your surveillance deployment at a glance.

Cruise for wider areas, zoom in for greater detail
With QVR system, users can easily manage & monitor multiple IP cameras in a real-time basis using web browsers and attain the first-hand status of monitored corners. You can directly adjust the PTZ (Pan/Tilt/Zoom) functions of supported cameras, flexibly monitoring every desired corner and detail. Auto-cruising is also supported to allow you to define preset positions for PTZ cameras to automatically adjust their monitoring angles to preset positions by the time interval.

Find out the critical recordings without the hassle
How to find suspicious alarm recordings from huge amount of recordings can be a challenge. QVR 5.0 provides an intuitive playback interface to you to easily distinguish between regular and alarm recordings in the timeline bar. For greater efficiency, you can also enable Intelligent Video Analytics (IVA) to quickly search videos corresponding to particular modes (includes motion detection, foreign/ missing object, out of focus and camera occlusion) to screen for critical recordings.

Optimize your video watching experience with video transcoding
The transcoding capabilities of the VS-8148U-RP Pro+ allows users a practical solution for watching videos stored in centralized locations via the Internet when they have low-bandwidth connections. This feature adapts to bandwidth limits and/ or devices that lack the hardware or codecs to play video files by converting a video file to a lower resolution before transferring it across the Internet. The original high definition video is still retained without any changes being made to it, balancing the whole surveillance system for local recordings and remote playback.

Flexible recording functions
QVR 5.0 provides flexible options to set up IP camera recording, including manual recording and scheduled recording. What can be even more convenient, you can set up the system to only record when motion is detected or other events occur. The smart recording function can also automatically switch the recording detail to a higher resolution when alarms are triggered. This greatly saves the cost spent on hard drives.

Economical expansion options
By installing the Storage Expansion app on a QNAP Turbo NAS, you can connect the VioStor NVR with the Turbo NAS via network to flexibly enlarge the total storage capacity of the VioStor NVR. If the expanded storage is not enough, QNAP REXP expansion enclosures can be used to expand the storage space on the connected Turbo NAS to support hundreds-of-terabytes raw capacity.

Availability: The storage expansion solution is available for VioStor NVR Pro(+) series with firmware v4.1.1 or newer and the Turbo NAS TS-X51, TS-X53, TS-X53U, TS-X63, TS-X70U, TVS-X71, TVS-X71U, TVS-ECX80, TVS-ECX80U series with QTS operating system v4.1.2.
