Multi-point file backup, access, and sync
The TS-451D2 centrally stores data and files, and supports common file sharing protocols, including SMB/CIFS, AFP and NFS for Windows®, Mac®, and Linux®/UNIX® devices. Coupled with Qsync (a utility that transforms a QNAP NAS into a secure, high-capacity data center for file synchronization), any file uploaded to the TS-451D2 becomes available for all connected devices (such as computers, laptops, and mobile devices). Hybrid Backup Sync helps you easily backup or synchronize data on the TS-451D2 to another QNAP NAS, remote servers, or cloud storage for disaster recovery. Additionally, QuDedup technology greatly improves the efficiency of multi-version backup to the destination storage, while optimizing storage utilization. You can install the QuDedup Extract Tool on your computer and restore deduplicated files to their normal status.
Enjoy a high-quality multimedia experience
Seamless integration with cloud data

Safeguard your environment with QVR Pro
QVR Pro is a modern NAS-based surveillance solution that simplifies camera management, storage space allocation, camera live view, and playback. Dedicated storage space for surveillance data can be configured on the TS-451D2 to optimize system performance, and surveillance feeds can be monitored at any time using the QVR Pro Client mobile app. Budget-constrained users can even use USB webcams as network cameras by using QVR Pro with the QUSBCam2 app.
Notes:
1. QVR Pro requires a QNAP NAS with at least 4GB RAM. QNAP NAS that do not meet this requirement should use Surveillance Station.
2. The maximum number of channels supported varies by NAS model, network configuration, and camera settings. For more information, visit https://www.qnap.com/go/qvr-nas-selector.
