video capture hardware refers to the physical device used for converting analog or digital DVI, VGA or video signal into a digital format that is readable by a computer. Usually the video capture hardware consists of a capture card, which "converts" the video input and sends it to the USB port, Ethernet or PCI Express bus. This article will focus on three types of these devices and weigh the advantages and disadvantages.
USB video capture cards are small devices plug into the USB port of the computer capture. In general, it works with Windows, Mac and Linux, and accept VGA and DVI. The advantage of using a USB capture card is that they are compact, easily transportable, and easily switch between different computers, and working with office machines and laptop.
Network-based video capture devices such as VGA2Ethernet provides high catch rates, are able to acquire VGA and DVI streams, and can also capture audio. They are also compatible with virtually any computer and can be accessed remotely if necessary. No other type of capture card provides a set of features such expansive. For this reason, if you choose the video capture hardware, a network-based solution would be more appropriate.
