I used similar cards from newegg.com and geeks.com with cameras, etc. The one thing we had to overcome was the IT staffer that wanted to build a PC. Since we wanted this CCTV to just work we ordered a Dell, slipped in the cards and let it run. The IT staffer was incensed over not having their way but since we don't get paid unless it works we told them what we thought about their plan.
