Similar photos are categorized into People, Places, and Things albums. Moreover, QuMagie features a built-in timeline scroll, customizable folder covers, iOS® Live Photo display and a powerful search tool, to provide you with the ultimate photo management and image sharing solution.

Real-Time 4K Video Transcoding

Featuring advanced Intel® UHD Graphics, the TS-251D supports dual-channel 4K 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 media files on an HDTV using the HDMI output or with Plex® Media Server to stream media files to mobile devices and media streaming devices (including DLNA®, Roku®, Apple TV® (via Qmedia), Amazon Fire TV® and Chromecast™). The QNAP RM-IR004 remote control (sold separately) can be configured using QButton to customize individual button actions, providing a more user-friendly NAS experience.

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

Multiple Ways To Enjoy Your Multimedia

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

Multimedia Console consolidates all QTS multimedia applications into one app for easier and centralized multimedia app management.

Cinema28 enables single-interface management of all 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 TV™, Apple TV® (via Qmedia), and Amazon Fire TV or set-top boxes.

Easy and Secure File Management

File Station centralizes files stored on your TS-251D and in the cloud. You can easily upload files from your computer, drag and drop files between folders, rename files, delete files, and configure file and folder permissions to prevent unauthorized access. Moreover, with Microsoft Office Online you can open and modify Microsoft Office documents stored on the TS-251D, without having to download Word documents, Excel worksheets, and PowerPoint presentations from your NAS to the PC. When it comes to sharing sensitive or confidential files on the TS-251D, you can use File Station to enhance data security effectively by encrypting files into a .qenc file, set a password, and then have file recipients use QENC Decrypter to decrypt the sent file.

Multi-Point File Backup, Access, and Sync

The TS-251D stores data and files centrally, and supports 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-251D becomes available for all linked devices, such as computers, laptops, and mobile devices. Hybrid Backup Sync helps you easily backup or synchronize data on the TS-251D 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.

Protect Important Data With Snapshots

Snapshots help protect your data by fully recording the NAS system state and metadata. You can use snapshots to quickly restore files to a previously-recorded state when files are accidentally deleted or modified, or when the system is compromised by ransomware. QNAP snapshots are block-based and only record modified data. Not only does this save storage space, but also reduces the time required to back up and restore data.

Model Snapshots per NAS Snapshots per volume or LUN
TS-251D-2G 64 32
TS-251D-4G 1,024 256

Extend NAS Functionality With The PCIe Slot

With a PCIe expansion Gen 2.0 x 4 slot, the TS-251D provides flexibility in extending NAS functionality and potential applications. To optimize system performance, install a QNAP QM2 card for M.2 SSD caching/10GbE connectivity and use with Qtier tiered storage for optimal system performance. You can also use the TS-251D as a wireless access point by installing a compatible QNAP QWA-AC2600 or QXP-W6-AX200 wireless network card to create a wireless media streaming environment. Moreover, by configuring the QXG-10GbE/5GbE network expansion cards, you can upgrade your network to high-speed connectivity with an existing CAT 5e cable. You can also boost the USB connectivity of the TS-251D by installing a USB 3.2 Gen 2 (10Gbps) card.

QVR Pro Safeguards Your Environment

QNAP’s QVR Pro surveillance solution allows you to arrange dedicated, independent storage space for surveillance data on the TS-251D and leverages scalable storage advantages. 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 surveillance feeds anytime with QVR Pro Client mobile app.

 Notes:
1. QVR Pro is available for the QNAP NAS models with a least 4GB RAM, QNAP NAS with 2GB RAM please 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.
