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

Watch NAS videos on any devices

With Intel® UHD Graphics 600, the TS-451D2 supports high-quality video transcoding, enabling the NAS to convert videos to universal file formats that can be smoothly played on multiple devices.

Note: The TS-451D2’s hardware provides hardware decoding, encoding, and transcoding capabilities. However, playback quality may vary due to factors including playback software, file formats, system usage, and available bandwidth.

4K HDMI output

With HDMI 2.0 output, the TS-451D2 supports the direct playback of multimedia on TVs and monitors. Resolutions of up to 4K (4096 x 2160) at 60Hz are supported, and when coupled with a wireless keyboard and mouse the TS-451D2 is transformed into a convenient media player.

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.
