Pros: None I could find, because it does not work.
Cons: No Windows 7 support. The way it is described seems like it is skirting around the fact. Mainly, this is an old product. It was a waste of my time and money. I was so eager to stream that I missed this info, and the fact that there are much cheaper capture devices that are way more compatible as well.
Cons: I can understand the vitriol at people who didn't see that it was a low profile card. However, I can't believe that there is a production card on the market with NO WINDOWS 7 DRIVERS. You cannot even shoe-horn the drivers from XP onto the system. DON'T BUY THIS IF YOU HAVE WINDOWS 7. P.S. I'm not yelling, I'm WARNING YOU!
Cons: Had a hard time placing it into the computer. It kept popping back out, but I was able to force it in somehow. When I was able to force it in, I discovered that the device did not support Windows 7. I should've read the details before purchasing.
Summary: When using 1 input, you get 30 FPS. When using 2 inputs, you get 2.5 FPS. When using 3 inputs, it drops to 0.7 FPS. 2.5 is acceptable for my usage. Just remember that the card is sharing one analog-to-digital converter over 4 ports. The more cameras hooked up, the more the card has to work at switching, syncing, and setting them up with your software.
Pros: Works very well with Linux and Zoneminder. Easy to install, includes a low profile bracket.
Cons: In linux, the bottom most plug does not appear to work. I am sure there is a work around, but I don't think it really matters because:
Summary: Only one Analog to Digital converter chipset instead of one chipset per port. This means that if you will record between the different inputs at the same time, your max FPS recording from one input will be decreased. (Think, sharing 30fps between 4 ports). Look up the word Multiplexing when it comes to CCTV to get some idea as to how this works. Again, I knew this going in. You don't need to record at 30FPS to get a good quality image of a subject...
Pros: Works like a charm in Linux. Drivers for the chipset are already installed in the latest kernels. Works great with ZoneMinder, making it an affordable DVR input card. Its a low profile card, and comes with a low profile bracket.
Cons: In Linux, one of the inputs does not work (bottom most port). I'm not sure why, or how to fix it, but I read this limitation going in (possibly due to the S-Video port using TWO inputs instead of just one).
Pros: I personally get no noticeably delay when viewing the input on my PC, allowing me to play my games through it while recording or streaming without a need for splitters or a TV. Your mileage may vary.
Cons: Included software leaves something to be desired, and when multiple sources are plugged in under Windows, only one seems to work; not one at a time, one period, it doesn't seem willing to switch between sources.
