We also enjoyed the Surveillance Station, which reminded us of the same feature found in the Synology DS107+. The main difference is the TS-109 Pro II, out of the box, supports two IP cameras, while the DS107+ supports only one (and you have to pay extra for it to support more, up to six cameras). Though TS-109 Pro II can support a maximum of only two cameras, the QNAP comes with a comprehensive list of supported cameras. We tried it with the Panasonic BL-C1, and it worked like a charm. We were able to record based on either a schedule (everyday from 8 a.m. to 5 p.m., while you're at work, for example) or motion detection. The video quality is the same, if not better, than that found in some tape-based surveillance systems.
Overall, we liked the NAS server's features and its desktop software, as well as its Web-based interface, which was easy to use and well-designed. The NAS supports SMB protocol, which means it can be accessed very easily on a local network just as you would access another computer in the network. The NAS server manages users just like a Windows XP machine, and you can assign access privileges down to a certain folder with no access, read-only, and read/write levels.
The QNAP TS-109 Pro II did well in CNET Labs' performance benchmarks. With a 1TB Hitachi DeskStar 7200rpm hard drive, the TS-109 Pro II scored 44.1Mbps and 42.5Mbps on our write and read tests, respectively. Among single-volume NAS servers we've tested of late, the QNAP's performance rates slightly above average.

Overall, the QNAP TS-109 Pro II worked smoothly in our testing process and stayed very cool and quiet even during the heavy loads. However, we found that during heavy loads its performance decreased significantly. For example, when we had it downloading a big file and record video via an IP camera, it would take up to 45 seconds or so to start playing a 1GB video file.
Service and support
QNAP backs the TS-109 Pro II with a one-year warranty. A phone support number is not listed on its Web site, but an online support form is available. There is also downloads section on the Web site for new firmware and application updates, as well as a forum where you can get help from others.
