QNAP VioStor VS-8248-PRO+ 48-Channel 8-Bay Network Video Recorder (No HDD) QNAP Outlet Sale

The QNAP VioStor VS-8248-PRO+ 48-Channel 8-Bay Network Video Recorder is an SMB-grade, tower-based network surveillance server that supports real-time video/audio monitoring, megapixel recording (up to 10MP), and playback from multiple IP cameras. Powered by a Dual-Core Intel Core i3 processor and 8GB of DDR3 memory, it is capable of recording videos from up to 48 IP cameras and offers up to 450 Mb/s throughput to ensure stable recording of multiple megapixel IP cameras.

Even without a PC, the NVR can be configured to perform monitoring tasks with local display by connecting a USB mouse, USB keyboard, and HDMI monitor to deliver lag-free live video monitoring in full HD (1920 x 1080) resolution. Using iOS and Android devices, the Vmobile app provides camera live-view, PTZ control, instant event notifications, video snapshot, video playback, and searching for videos by date and time. Another mobile app, Vcam, allows you to turn your mobile device into a network camera and directly save recordings to your VioStor NVR for portable surveillance options.

The QSCM Lite is a free app provided by QVR that allows you to deploy up to 16 QNAP NVRs and 256 cameras to conduct central monitoring, playback, and management. With no extra server hardware required, QSCM Lite can turn the NVR into a CMS server. QSCM Lite can be freely downloaded from the integrated NVR App Center. The QVR 5.1 software offers a multi-window design that allows concurrent multitasking and enables administrators to switch between tasks.

QVR 5.1 provides an intuitive playback interface for distinguishing between regular and alarm recordings in the timeline bar. You can also enable IVA (Intelligent Video Analytics) 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.

The QVR 5.1 software provides flexible options to set up IP camera recording, including manual recording and scheduled recording. 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.

You can directly configure IP camera recording schedules when needed without leaving the Live-view page and 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 and drag and drop the IP camera icons to the right place on the e-map for monitoring your surveillance deployment.

With the QVR system, users can manage and monitor multiple IP cameras on 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 for 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.

The transcoding capabilities of the NVR enables users to watch 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. By installing the Storage Expansion app on a QNAP Turbo NAS, you can connect the VioStor NVR with the Turbo NAS via a 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 for increasing storage capacity.

The NVR supports multiple port-trunking modes, enabling IT administrators to set up link aggregation to increase total data transmission capability. Failover is also supported to ensure continuous system operation. The supported port-trunking modes are Balance-rr (Round-Robin), Active Backup, Balance XOR, Broadcast, IEEE 802.3ad, Balance-tlb (Adaptive Transmit Load Balancing), and Balance-alb (Adaptive Load Balancing).

The NVR supports comprehensive RAID configurations and hot-swap functionality for replacing hard drives without interrupting system operation. RAID recovery technology also assists if any healthy drives are accidentally removed from a degraded RAID volume. The system can be recovered to degraded mode by reinserting the wrongly removed hard drives so the data can still be accessed. The Global Hot Spare function also allows a drive to automatically replace a failed drive in a RAID volume, preventing data from being lost.
