Internal cards have to be installed inside the computer in one of the expansion slots. Some consumers aren’t comfortable gambling with messing around inside their computer or don’t want to shell out the bucks to pay someone else to install it for them. This is the main reason that keeps them away from the internal cards; which could be a big mistake. Internal cards are much more flexible with their selection, features, and cost. They are generally less expensive than the external ones.
Pros: Internal cards have a broader selection range, with better features, to choose from. They don’t cost as much as external cards. It is easier to find an internal card that will work with Microsoft Vista.
Cons: Internal cards have to be installed inside the computer. This will be a potential problem for people with older systems. PCs built before 2004 may not have the PCI expansion slot that is required for the installation of the internal cards. Not all cards are compliant with Microsoft Vista.
When to use: Internal cards are best when you don’t need an expensive solution and just want to capture video files. If you are using Microsoft Vista, you will have a better chance finding an internal card that is compatible.
