Digital video recorder (DVR) capture cards receive video feeds from DVRs onto the computer's hard drive for playback or editing. They have four or more ports for connecting to multiple DVRs, as well as output ports for monitors or other display devices. They are commonly used for security and surveillance applications. They usually come with driver software, which provides an interface for operation and offers additional functions such as DVD burning, motion sensors, and image watermarking.
