The Tral31 mini Digital Video Recorder provides easy integration with traditional analog systems this DVR digitizes analog video into crisp, real-time MPEG video streams at a maximum frame rate of 6.5 frames per second on each channel independent of resolution. The Tral31 can connect up to four analog cameras and transmit digital video from all four channels simultaneously via an Ethernet connection. Tral31 is built based on non-PC type operating system (OS).
