Fully unleash the potential of fisheye cameras

QVR Pro supports all of the standard fisheye cameras available on the market, and features Qdewarp technology that converts distorted parts of the original images into proportional ratios. QVR Pro also provides industry-leading functions, including allowing a single fisheye camera’s image to be simultaneously viewed in nine channels from different angles and cross-platform hardware-accelerated decoding for fisheye camera images. QVR Pro ensures higher surveillance performance for greater security while providing deployment flexibility.

Easily monitor every corner

Previously you needed multiple cameras to monitor every corner of an environment. Now you only need to deploy a centralized single fisheye camera to monitor the whole area - allowing you to enjoy higher surveillance efficiency with a more budget-friendly cost.

Past: multiple cameras required

Now: only a single fisheye camera needed

Simultaneously view fisheye camera images from different angles

You can display a single fisheye camera’s image in up to nine channels at one time for a more detailed view from different angles. This does not affect the ongoing recording's video quality.

Multiple angles

Cross-platform hardware-accelerated video decoding

When converting fisheye images with common monitoring software, the device CPU load will be as high as 75%. However, with QVR Pro Client, the device CPU load only reaches 25% even when simultaneously converting nine channels.

Note: Hardware-accelerated video decoding is achieved by using a graphics card (or integrated graphics in the CPU) to reduce the device CPU load, allowing you to monitor more cameras at the same time while the device continues operating smoothly.

Motion detection in budget-friendly cameras - including USB webcams!

In the past, QVR Pro only provided event recording and event notifications for expensive cameras with integrated motion detection. QVR Pro now provides motion detection even for budget-friendly cameras and USB webcams as long as they can stream their footage to QVR Pro (e.g. through RTSP protocol). QVR Pro allows you to build a more-secure surveillance system for homes and office environments on an affordable budget.

Note: For cameras lacking integrated motion detection, QVR Pro provides up to two channels for motion detection analysis and supports resolutions up to 1080p.

QVR Pro Client: live view and playback

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

The updated Region of Interest (ROI) feature supports multiple regional images from the same camera in live view and playback mode. You can define and enlarge multiple areas on the overview image with no selection limitations or additional licenses required.

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.


If an event occurs, you can quickly know the camera’s location on the e-map to ensure a timely response.

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.

Performance Improvements

With advanced video indexing technology, you can have up to ten-times faster playback speeds than the previous version and up to five-times faster exporting of surveillance recordings.

What’s the difference between QVR Pro and other NAS-based surveillance systems?

In the past, surveillance applications were just one of the many applications on NAS. There was no dedicated storage for surveillance recordings and usually the system performance was limited, making it unsuitable to fulfill the requirements of professional surveillance systems. QVR Pro, QNAP’s brand-new surveillance application, introduces the concept of "dedicated storage space" to ensure that the storage is fully reserved for QVR Pro and the system performance will not be impacted by other applications on NAS.

  • Open Event Platform

    The API can connect QVR Pro with a wide range of IoT applications. These resources can be easily shared to make the surveillance system secure and more intelligent.

  • Dedicated Storage

    QVR Pro has an independent recording space from QTS, ensuring dedicated storage space, high-quality recordings, and no performance interference.

  • Expandable Storage Capacity

    You can easily expand your storage capacity by simply connecting expansion enclosures,to your NAS or by using QNAP’s VJBOD to use the unused storage of another QNAP NAS.

Powerful camera management and support

QVR Pro supports thousands of camera models from over 140 brands and a variety of image formats, allowing you to quickly build different surveillance solutions tailored to your environments while providing convenient camera management. Check camera compatibility

  • Supports ONVIF/ QUSBCam2

    QVR Pro supports over 140 brands and ONVIF cameras. You can also install QNAP’s QUSBCam2 app to turn a budget-friendly USB webcam into a networked camera.

  • Cross-network Camera Search

    Easily add cameras from different networks, providing greater convenience for organizations with multi-network environments.

  • Add and Manage Camera by Batch

    Save time when deploying large numbers of cameras by batch-adding cameras. Cameras with the same brand/model can be added with the same settings.

  • Open Event Platform

    Record into QVR Pro by using the RTSP/RTMP link with no integration needed. Multiple video sources are possible, and are not limited to IP cameras.

  • Optimal Bandwidth Management

    Assign dedicated bandwidth to each camera to optimize the use of QVR Pro Appliance system resources and ensure smoother recordings.

  • 360-degree Camera

    By supporting 360-degree cameras, you can easily monitor every corner of your environment without having to deploy large numbers of cameras.

Flexible recording space management

Pre-allocate storage capacity and assign dedicated storage space for each camera’s recordings based on the camera's monitoring scope and importance. You can also set the maximum and minimum recording days for individual cameras and get a usage overview of all video recording spaces at a glance.

Allocate System Resources for Event Recordings

Assign separate streaming resources and allocate dedicated storage spaces for general recordings and event recordings. This ensures that important events have more system resources. For example, recording events to an SSD can ensure optimal read and write performance to speed up event alerts to reduce your response time.

A Failover Recording Space for 24/7 Recording

You can set a spare volume in the recording space for your recordings. If the original volume fails, recordings will be stored on the spare volume.

Expandable Capacity for Long-term Archiving

The high scalability of QNAP NAS provides key advantages to QVR Pro. When running out of recording spaces, you can expand your storage capacity by connecting expansion enclosures to your NAS or by using QNAP’s VJBOD to use the unused storage space of another QNAP NAS.

Monitor at anytime anywhere with the QVR Pro Client mobile app

The QVR Pro Client mobile app provides multiple display layouts and allows you to monitor multiple channels simultaneously. Under single channel view, you can quickly switch between live and playback modes. 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 control PTZ cameras and the camera’s preset point from the app. Other features include camera view from the e-map and mobile notifications.

The most open surveillance platform

"Open" is the core design concept of QVR Pro. QNAP invites developers to use QVR Pro’s resources to build their own network monitoring automation services. Various APIs are provided by QNAP to quickly integrate a wide range of cameras, configure event alerts and recordings, and to integrate with IoT devices.

Specific privilege settings

QVR Pro provides detailed privilege settings, allowing for setting individual or group access privileges, providing suitability for environments of all sizes. In addition to the default roles (including Administrator, Supervisor and Viewer), you can create new roles and give customized access to view specific layouts and channels, and also the e-map.
