I recently purchased 10 Bosch 0938/25C Envirodome cameras for $100 and I want connect one or two of them to my home computer. I have no CCTV experience and I've contacted Bosch about this and the only answer I got from them is to refer to the users manual on their website, which doesn't help at all. Could some please help me? Do I just need to purchase a BNC DVR card and install in my computer and download some software to control them up the cable? Any help anyone can provide will be greatly appreciated.
