QVP-41B 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 share NAS system resources and storage space, surveillance performance could be impacted. The QVP-41B 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-41B integrates PoE switch functionality and supports connecting all kinds of PoE cameras and devices. It 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-41B to start the installation process.


Intelligent PoE Management for High-Power IP Cameras

The QVP-41B is compliant with the IEEE 802.3at PoE+ standard and has sixteen ports with 30-watt Gigabit PoE capabilities. The QVP-41B can supply a total power budget of 140 watts to meet the demands of bullet cameras, fisheye cameras, 4K PTZ cameras and Speed Dome cameras compliant with the ONVIF® standard; or high-power devices such as 4K PTZ camera, IP phones, LED lights, and digital signage. The QVP-41B supports intelligent PoE management functions, including scheduling, power supply prioritization, and power enabling/disabling. You can obtain real-time network connection status and power consumption information of PDs and configure PDs simultaneously to promote an energy-saving PoE network.

Comprehensive camera support and management

The QVP-41B supports thousands of camera models from over 150 brands with a variety of image formats (including cameras that use ONVIF and RTSP/ HTTP streaming). Even USB webcams are supported, allowing home and budget-conscious users to quickly build surveillance solutions tailored to their environment while providing convenient camera management.

Minimalist design with 4K 60Hz HDMI output for fashionable retail space

The QVP-41B has a modern design and quiet cooling system that provides dependable system performance while minimizing heat and noise. This stylish appearance allows the QVP-41B to easily fit in with modern retail spaces and showrooms. The QVP-41B combines the functions of a PoE switch, NVR, NAS and router, providing HDMI 2.0 output for direct playback of live feeds up to 4K (3840x2160) 60Hz resolution. By consolidating the functions of multiple devices in a near-silent and stylish form factor, the QVP-41B satisfies the requirements of smart retail surveillance environments.

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.


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.


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.


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.


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.

Complete Surveillance Infrastructure Deployment for Smart Retail

Combining QVR Pro surveillance software, HBS remote backup, and QuWAN SD-WAN solutions, the QVP-41B is a total package for surveillance deployment. Businesses can centrally manage video capture, playback, and processing to benefit from a cost-optimized smart surveillance solution.
