    High image quality, surveillance without blind spots.

    Supports multiple regional images from the same camera in live view and playback mode.

  • E-map

    Upload a set of floor plans and mark IP cameras on them.

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

  • Multiple Notification Methods

    When an event occurs, it will notify with mobile ringtones and notifications, helping to reduce response times.

    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.

  • Qdewarp Technology

    Innovative Qdewarp technology enables users to view standard fisheye camera recordings in proportional ratios and sizes without affecting original recordings.

    You only need one 360-degree fisheye camera rather than using 3 IP cameras for different recording angles, greatly helping reduce deployment costs.

Universal surveillance monitoring 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, metered or capped, you can choose the low-bandwidth mode to view a bandwidth-optimized stream without affecting the quality of recordings. You can also 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.

QVR Elite is extraordinary because its attention to details

Lower system requirements - only 1GB RAM!

QVR Elite runs on a wider range of QNAP NAS, with only 1GB RAM required.

Note: At least 2GB RAM is recommended for the smoothest usage experience.

Specific Privilege Settings

You can leverage NAS privilege settings for QVR Elite, including users and user groups. QVR Elite also provides detailed in-app 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.

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.

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.
