Recommended NAS for Surveillance Cams?

[WMConey]

Looking for a simple config that would let me run 3 cams for my home security system. I've been trying to use my existing QNAP 431, but it stalls out apparently from lack of memory.

TIA

How about QNAP TS-251+? Should be powerful enough to handle the task, I'm using it with two cams and it works perfectly.
