The 412 died on me ~ 2 years ago and I replaced it w/ a larger DS1817+ which probably has enough horsepower to handle the cameras w/o degrading performance as much. I was using it on a DS412+ at the time, which was IMO slightly underpowered for the camera load. I haven't looked at it in awhile, but it's likely improved since I last used it. I used Synology's surveillance-station software for a short while, but only w/ 2 cameras as I didn't think spending more for the licensing made sense relative to the cost of the cameras.
