QVP-21C vs. other NAS-based surveillance systems. What’s the difference?

In a conventional NAS-based surveillance system, surveillance is just one of many applications available to users. As all these applications need to share NAS system resources and storage space, surveillance performance could be impacted. The QVP-21C QVR Pro Appliance overcomes this by providing dedicated storage space and reserving full system resources for surveillance, delivering the utmost performance to fulfill professional surveillance system requirements. The QVP-21C also comes with built-in camera channel licenses and essential applications to enable local installation without requiring an internet connection. Simply install the hard drives and power up the QVP-21C to start the installation process.

High-capacity video surveillance storage solution

QVP-21C is a professional network surveillance server, compatible with 8,000+ IP cameras of 200+ brands and thousands of ONVIF network cameras.

Build a complete surveillance solution with affordable deployment

All-in-one surveillance

Say goodbye to expensive and complicated PC NVR. QNAP network surveillance server integrates QVR Pro software and high-performance hardware.

Dual HDMI™ output for viewing multi-channel videos

Use the dual HDMI™ outputs of QVP-21C for dual-screen extension to play and switch between multi-channel videos on two monitors.

Surveillance failover

Install the high-availability QVR Guard app on another NAS to automatically takeover recording tasks if QVP-21C fails.

Live surveillance monitoring, remote management, and smart AI

Live surveillance video monitoring

Monitor live feeds and receive alert notifications from client applications on PCs or mobiles.

Large-scale central management

Centrally control up to 256 Surveillance NAS (licenses sold separately) in different locations via QVR Center.

AI surveillance event search

Instead of manually searching through a whole day of event videos, QVR Smart Search helps you efficiently search through hundreds of hours of video recordings from hundreds of cameras to find specific events.

MP4 surveillance videos

Videos are saved using the non-proprietary MP4 video format. 

Faster facial identification with integrated Intel® OpenVINO™ AI engine.

With integrated Intel® OpenVINO™ AI computing resources, the QVP-21C accelerates AI facial recognition and object identification performance in QVR Face without impacting other applications or services.

Motion detection using budget-friendly USB webcams

Standard surveillance systems normally only support event recording and notification functions for expensive cameras with integrated motion detection. The QVP-21C provides motion detection even for entry-level cameras and USB webcams. As long as your camera can stream its footage to the QVR Pro appliance (e.g. through RTSP protocol) it supports motion detection, allowing you to build a budget-friendly, motion-detecting surveillance system.

QVR Pro Client

The QVR Pro Client software can be installed on Windows® and Mac® devices, allowing you to monitor from different platforms and flexibly switch from live view or playback mode to take full control over monitored areas.

Live view and playback

Monitor the live view of multiple channels and play recordings on a single interface. You can also view recordings at a specific time by clicking the timeline or by defining a time range.

Region of Interest

The Region of Interest (ROI) feature allows for viewing multiple regional images from the same camera in live view and playback mode. You can define and enlarge multiple areas to watch the area more closely.

Qdewarp Technology

The innovative Qdewarp enables users to view standard fisheye camera recordings in proportional ratios and sizes without affecting original recordings. The distorted parts on the edges can be turned into a clear panoramic view.

Multiple Notification Methods

The event notification provides multiple ways of being informed of emerging events, including flashing red borders of channels, alert buzzers, and the motion icon on the e-map.

Easy remote monitoring with the QVR Pro Client mobile app

The QVR Pro Client mobile app allows you to remotely monitor multiple channels simultaneously. If your network connection is slow or metered/capped, you can choose the low-bandwidth mode to view a bandwidth-optimized stream without affecting the quality of recordings. In addition, you can remotely set the camera’s preset point or control the PTZ cameras within the app. 

Extend hardware warranty up to 5 years

The QVP-21C is backed by a 3-year warranty at no additional cost. You can also purchase a warranty extension that extends your warranty coverage up to 5 years.
