PCI Cards or Peripheral Component Interconnect video cards have the ability to manage videos and images displayed on monitor screens. The convert incoming video signals into electronic signals that can be displayed on the monitor and are plugged into the computer’s PCI rack alongside other expansion cards. A DVR PCI card can be used to connect screens and DVR or Digital Video Recorders and are primarily used in DVR security systems.

When looking for a DVR PCI card, there are a few things to consider before purchasing. Firstly, determine whether the installed memory in the DVR PCI card is large enough to give you crisp video displays. Anything below 64 MB is generally deemed low quality while 128 MB sizes and higher is considered more suitable for DVR systems.

A DVR PCI card’s data width is also another key measure of its quality. The data width determines the colour spectrum that the card can provide. Look for a DVR PCI card that comes with at least 256-bit or 512-bit data width if you’ll be using heavy graphic applications. However, for most general applications, anything from 64-bit up to 128-bit would suffice.
