QNAP QVP-21C 2-Bay High-Performance NVR for SMBs and SOHO, Intel Quad Core Upto 2.6 GHz, 8GB DDR4 (16GB Max), 2x M.2, 4x USB, 2x HDMI, 2x 2.5 GbE, Come with 8 Camera license (16 Max)
QVP-21C
The QVP-21C QVR Pro appliance is a tower-based network surveillance server with an Intel® Celeron® quad-core processor that supports eight free IP camera channels and up to sixteen IP camera channels. Offering an economic and high-performance software and hardware integrated video surveillance solution, the QVP-21C fulfills requirements for secure, reliable, and centrally-managed video surveillance storage for small businesses and offices.
Supports ONVIF cameras
Compatible with thousands of cameras from over 190 brands and ONVIF standards.
Long-term model
The QVP-21C will be available and supported by QNAP for an extended period, up to 2029.
Dual HDMIâ„¢ outputs
Play and switch between multi-channel real-time 4K videos on two monitors with extended display.
High-performance NVR
Boost your surveillance data transmission efficiency with dual-port 2.5GbE, a USB 3.2 Gen2 10Gbps port, and 8GB RAM.
RAID protection
Unlike traditional DVR and NVR, the QVP-21C protects your data from drive failure with RAID.
Lightweight AI surveillance applications
QVP-21C incorporates QNAP smart surveillance applications and supports Intel® OpenVINO™ AI engine and Edge TPU expansion via M.2 SSD slots to boost facial recognition performance in QVR Face.
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 6,000+ IP cameras of 190+ 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 HDMIâ„¢ output for viewing multi-channel videos
Use the dual HDMIâ„¢ 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.
Comprehensive camera support and management
The QVP-21C supports thousands of camera models from over 190+ 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.
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.
Expand your surveillance applications – Control, failover, and facial recognition
QVR Center - QVR Pro control center
Centrally manage multiple QVR Pro servers installed in different areas. You can also centrally monitor live feeds, play back recordings and receive event notifications from multiple QVR Pro servers, helping you reduce response times to events.
QVR Guard - High-availability failover management
Protect QVR Pro from system failure to ensure uninterruptible surveillance recordings. If your QVR Pro fails or crashes, QVR Guard automatically takes over recording tasks, providing dependable redundancy for your surveillance system.
QVR Face - Smart facial recognition and analytics
Obtain real-time video analytics from connected cameras and use them to set profiles, groups, and event notifications for instant facial recognition. This is ideal for smart retail, door access management, and VIP welcoming systems.
Smoother surveillance streaming with 2.5GbE connectivity
Connect the two built-in 2.5GbE ports to a QNAP 2.5GbE switch to benefit from a smoother surveillance streaming experience.
