QNAP provides a wide range of multimedia applications. You can manage all apps through the media console to simplify management.

HBS backup and syncs NAS data with other remote servers or cloud storage, while QuDedup deduplicates data at source to reduce network bandwidth and storage space.

Use VJBOD (Virtual JBOD) to expand your storage capacity by using unused storage from other QNAP NAS. Connect up to two TR series USB storage enclosures.

Dual-core Intel® Celeron® J4025 processor and AES-NI hardware encryption

Powered by 2.0 GHz dual-core Intel® Celeron® J4025 processor (turbo up to 2.9 GHz), DDR4 RAM (up to 8 GB), Gigabit LAN port and supports SATA hard drives 6 Gb/s, the TS-251D combines network expansion cards to ensure consistent read/write performance.

Real-time 4K video transcoding

Featuring advanced Intel® UHD Graphics technology, the TS-251D supports hardware decoding and real-time transcoding in two 4K channels, allowing you to convert videos to universal file formats that can be played smoothly across multiple devices*. You can also watch high-quality 4K media files on an HDTV using the HDMI output or use with Plex® Media Server to stream media 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 the actions of individual buttons, providing a more user-friendly experience with the NAS.

*TS-251D hardware provides hardware decoding, encoding and transcoding functionality. However, playback quality may vary due to factors such as playback software, file formats, system usage and available bandwidth.

De nombreuses façons de profiter de votre multimédia

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

Application Cinema28

Cinema28 provides single interface management of all your media files and can stream files to all connected devices in your home.

Multimedia Console

Media Console consolidates all QTS media apps into a single app for easier and centralized media app management.

QMedia App

Qmedia makes it easy to stream music, photos and videos to Android TV™, Apple TV® (via Qmedia), Amazon Fire TV or set-top boxes.

Simple 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 edit Microsoft Office documents stored on the TS-251D, without having to download Word documents, Excel spreadsheets 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 effectively enhance data security by encrypting files in a .qenc file, setting a password, and then asking file recipients to use QENC Decrypter to decrypt the sent file.

Hybrid Backup

Multipoint file backup, access and synchronization

The TS-251D stores data and files centrally and supports file sharing protocols including SMB/CIFS, AFP and NFS devices for Windows®, Mac® and Linux®/UNIX®. Coupled with Qsync (a feature that turns a QNAP NAS into a secure, high-capacity data center for file synchronization), any file downloaded to the TS-251D will be made available on all linked devices, such as computers, laptops or mobile devices. Hybrid Backup Sync lets you easily back up or sync datato other QNAP NAS, remote servers, or cloud storage for easy disaster recovery. Additionally, QuDedup technology greatly improves the efficiency of multi-version backup to destination storage, while optimizing storage utilization. You can install the QuDedup extraction tool on your computer and restore the deduplicated files to their normal state.

Protect your 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 saved state when files are accidentally deleted or modified, or when the system is compromised by ransomware. QNAP snapshots are block-based and save only changed data. This not only saves storage space, but also reduces the time needed to back up and restore data.

Increase the functionality of your NAS with the PCIe slot

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

PCIe expansions

QVR Pro protects your environment

QNAP’s new QVR Pro surveillance solution allows you to organize a dedicated and independent storage space for surveillance data on the TS-251D and leverage the benefits of QTS storage management. With QVR Pro, camera management, storage space allocation, camera live view and playback become much easier. You can also use USB webcams as network cameras with the QUSBCam2 app, and remotely monitor your surveillance feeds anytime with the QVR Pro Client companion mobile app.

Remarks :
1. QVR Pro is available for QNAP NAS models with at least 4GB RAM. With a QNAP NAS with 2GB RAM, please use Surveillance Station.

Maintenance service in express exchange of a SYNOLOGY or QNAP NAS

We offer an express D+1 exchange service for your NAS and its disks.

Why offer maintenance when a NAS server is guaranteed by the manufacturer for 2 or 3 years depending on the model ?

The warranty is a return to manufacturer warranty, i.e. you must return the equipment in place to the manufacturer through your supplier. This evaluates the fault and replaces the faulty elements. This operation takes about 15 days with a minimum of 3 to 5 days of return transport. This corresponds to an unavailability of your NAS server for approximately 3 to 4 weeks without any time commitment.

The Express exchange service in 3 categories :

  • Express D+1 exchange for the NAS server without disks* in 3-year or 5-year version,
  • Express D+1 exchange for the NAS server with Standard disks* (WD Blue/Red/Purple, Seagate Ironwolf/Skyhawk, etc.) in the 3-year or 5-year version,
  • Express D+1 exchange for the NAS server with Enterprise* disks (WD Red PRO, Ironwolf PRO, Ultrastar, EXOS, etc.) in the 3-year or 5-year version.

We send by express carrier the NAS box or the failed disk directly to the address provided by the user. A transport voucher allows the return of broken down equipment. In the event that the equipment is not returned within 15 days, this will be invoiced to the user.

*The service must be acquired within a maximum of 3 months following the purchase of the product.
