It's much easier to make a good choice than buying a NAS for Plex use. There are plenty of NAS enclosures to pick from. Then you have other NAS enclosures like the QNAP TS-251D, which offer immense value at a slightly lower price. If the DS220+ isn't quite what you're after, there's always the ASUSTOR AS3102T v2, which is similar in many ways. It even comes with two camera licenses for free, allowing you to install your favorite two cameras and get started immediately. It has mostly everything you need to get the job done, including two drive bays, an Intel processor, somewhat affordable price tag, and a fantastic OS to boot. The best NAS enclosure for home surveillance and setting up some cameras to protect your property is the Synology DiskStation DS220+. Having the two hard drive bays mirror saved footage also restricts overall capacity. The only drawback with the AS3102T v2 is the DDR3 RAM, which is also non-upgradable. There's plenty of support here for all the popular camera brands and you'll have no issue setting them up with the ASUSTOR ADM OS.

You can use up to four cameras with this NAS enclosures before needing to buy more licenses. The best part is ASUSTOR manages to one up Synology by including an additional two free camera licenses. This makes the AS3102T v2 ideal for surveillance and as a workstation for quickly viewing feeds. Secondly, there are two drive bays for RAID configurations (with the potential for further bays with expansion units), and even an HDMI output for a connected display. Firstly, we have an Intel Celeron processor, which is more than enough for up to 25 cameras. The ASUSTOR AS3102T v2 is one of the company's more affordable home NAS enclosures, but the company still managed to pack it full of capable internal components that make it a compelling choice for home surveillance.
