Description

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 HDMI 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.

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.

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.

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.

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.
