This application is a combination of a digital video recorder and a video display server and is part of a larger communication and surveillance system on a train. A total of four digital video recorder units and two video display servers are used per train set, each housed in its individual 4U 19" CompactPCI rack.
The digital video recorder unit captures closed circuit television (CCTV) images to disk and stores event data collected from the set.
