Extend NAS functionality with the PCIe slot

With a PCIe expansion slot, the TS-251B provides flexibility in extending NAS functionality and potential applications. Install a QNAP QM2 card to provide M.2 SSD caching/10GbE connectivity and use with Qtier tiered storage for optimal system performance; use the TS-251B as a wireless access point by installing a compatible wireless network card (such as the QNAP QWA-AC2600) to create a wireless media streaming environment; or boost the USB connectivity of the TS-251B by installing a USB 3.1 Gen 2 (10Gbps) card.

Multiple ways to enjoy your multimedia

QNAP provides a wide range of multimedia applications for you to easily enjoy photos, music, and videos.

• Video HD is a free KODI add-on that combines KODI's streaming and video decoding capabilities and fully supports Video Station's features
• Cinema28 allows for single-interface management of all your media files and can stream files to every connected device throughout your home.
• Qmedia allows music, photos and videos to be effortlessly streamed to Android TVs or set-top boxes.

Multi-point file backup, access and sync

The TS-251B centrally stores data and files, and supports SMB/CIFS, AFP and NFS protocols for file sharing across Windows®, Mac®, and Linux®/UNIX® devices. Coupled with Qsync (a utility that turns a QNAP NAS into a safe, high-capacity data center for file synchronization) any file uploaded to the TS-251B will be made available for all linked devices, such as computers, laptops and mobile devices. Hybrid Backup Sync can help you easily backup or synchronize data on the TS-251B to other QNAP NAS, remote servers, or cloud storage for easy disaster recovery.

Real-time 4K video transcoding

Featuring advanced Intel® HD Graphics, the TS-251B supports dual-channel 4K H.264 hardware decoding and real-time transcoding, allowing you to convert videos to universal file formats that can be smoothly played across various devices*. You can also watch high-quality 4K@30FPS media files on a HDTV using the HDMI output or use with Plex® Media Server to stream media files to mobile devices and media streaming devices (including DLNA®, Roku®, Apple TV®, Amazon Fire TV® and Chromecast™). The QNAP RM-IR004 remote control (sold separately) can be configured using QButton to customise the actions of individual buttons, providing a more convenient NAS experience.

*The TS-251B’s hardware provides H.264 hardware decoding, encoding and transcoding capabilities. However, playback quality may vary due to factors including playback software, file formats, system usage, and available bandwidth.

Protect important data with snapshots

Snapshots help protect your data by fully recording the NAS system state and metadata. If files are accidentally deleted or modified or the system is afflicted by ransomware, you can use snapshots to quickly restore files to a previously-recorded state. QNAP snapshots are block-based and only record the changed data. Not only does this save storage space but also reduces the time required to back up and restore data. The TS-251B supports up to 1,024 snapshots per NAS and up to 256 snapshots per volume or LUN.

QVR Pro safeguards your environment

QNAP’s QVR Pro surveillance solution allows you to arrange a dedicated, independent storage space for surveillance data on TS-251B and leverage the advantages of scalable storage. With QVR Pro, camera management, storage space allocation, camera live view, and playback is greatly simplified. You can also use USB webcams as network cameras with the QUSBCam2 app, and remotely monitor your surveillance feeds at any time with QVR Pro Client’s companion mobile app.
