if you are looking for something that is like a security camerera setup, Go 
to Ebay and do a search for DVR. I bought some cards from a guy in Hong Kong. ( 
units shipped from US) Each card will record 4 inputs per card and 4 cards 
can be  put in one pc.   Cost ????? About 25.00 us with shipping.

If you can't find them, contact me offline, I will see if I can find the link 
if he is still selling them.  Jameco sells the same card for about 229.99 and 
I have seen several adds where they are 199.00..... They work, I have two of 
them
