Thank u for responding. and yes i'm pretty sure it's a clone.
well, i bought it from another biz owner, and it's a Compaq built desktop style PC.. i've got the picture now, my problem was my BNC cabling, it was crappy or broken.. unsure which it was.. but the picture is working fine now.
My only real problem now is that it's going to fill my 10 gig partitioned HDD now..(C:\ is 10 gig with windows installed... D:\ is 10 gig dedicated as a structure for diginet) i've also found.. it's not diginet center turning the PC off. it's diginet SITE that does it.
also if i can ask, does the length of the BNC cord matter? because i'm using 2 cameras, each with 50-75 ft. of cabling.
