Extra Features

Modern NASes cannot do without numerous additional services such as multimedia server or download station. The iTunes server of this NAS is implemented with the Firefly software. It indexes mp3 and wma files located in the common Qmultimedia folder.

The UPnP AV media server is implemented through one of the best programs available, TwonkyMedia. You can access its web-interface for setting it up. There, you can add into the file database any common folders. The server indexes most multimedia formats including jpg, png, bmp, tiff, gif, mp3, wma, m4a, aac, ogg, wav, avi, mpeg, mp4, m4v, mkv, wmv, mkv, ts, m2ts, vob, mov. It depends on your player whether you can play the files. At the default settings the media server creates special virtual folders for certain types of multimedia files: by date for photographs and by album, artist and genre for music. The only way for video files is directories, though. Besides files, the integrated server can broadcast radio stations.

The Multimedia Station section also contains an enhanced web-browser of files in the Qmultimedia folder. Particularly, you can keep your database of users, view a slideshow and check out the exif information of photographs. This feature can be useful for publishing your photo albums on the Web.

Web developers should appreciate the opportunity to place current or test projects on the NAS. The system offers Apache (2.2.6), PHP (5.2.8) and MySQL (5.0.67) with phpMyAdmin.

The autonomous file download module is going to be necessary for most users. It supports FTP, HTTP and BitTorrent. For the first two protocols download tasks are specified as links with optional user name and password and destination folder. BitTorrent offers more settings: maximum of active download tasks (up to 10), download and upload speed limits, port range, protocol encryption and schedule (one time period per day). Each torrent may have an individual seeding time after being downloaded. According to the integrated monitoring system, ten download tasks load the CPU fully although there is a lot of free memory left. This feature can only be controlled from the administrator account.

You can use the web interface or the QGet utility. The latter has a special icon for drag-and-dropping downloads to start. The following download info is shown: name, status, size, percent complete, speed, estimated time left, rating and DHT activity. The integrated client is inferior to PC-based programs of this kind, but is quite functional anyway.

The video surveillance system works only when you update the firmware from the site or disc. It is similar to the systems installed into special-purpose QNAP products. The TS-439 Pro is compatible with video cameras that support MJPEG and MPEG4.

This system can only be used via Internet Explorer for which the manufacturer has provided special ActiveX modules. Despite the high-performance processor, only two video cameras are supported (the March firmware update supports four cameras). For each camera you can specify access parameters, recording quality, and a schedule. You can set the disk space limit for all recordings and re-recording mode. Besides a live window, there is a page with recorded events where you can filter out the necessary ones, view in a separate window, delete or download to the PC. If the camera supports PTZ, you can use the latter in the live window. The total of supported models is over 50 from Axis, D-Link, Level 1, Panasonic, etc.

If you have high data security requirements, you can use the integrated backup tools. You can save backup copies to an external drive or via the LAN. In the first case you choose common folders, an external disk (USBdisk1 or eSATADisk1), operation mode (copying or synchronization, and a schedule – start right now, start on a specific day of the week, or start upon the connection of a disk). The same can be done with the remote replication using rsync. Not only QNAP products but also standard servers are supported. You can create a few tasks and specify a remote server, local folder and schedule for each task. Encryption and compression can be enabled.
