The CTR-1475 is a real-time MPEG-4 video compressor, encoder and frame grabber module designed to capture up to four concurrent high-quality analog video and audio streams, encode them in compressed MPEG-4 or AVI formats, and send them to an embedded computer over the 32-bit PCI bus.
Up to four CTR-1475
Featuring an onboard RISC microcontroller dedicated to handling the computationally intensive video compression procedure, this PC/104-Plus form factor module supports up to four cameras at a time, enabling a lower-end system processor or up to four CTR-1475 modules to be used in a single system (supporting up to 16 cameras). Because of its compact size and rugged design, the board is especially suited for live video surveillance applications where rugged environmental conditions (vibration/extreme temperatures) and space constraints exist (i.e. in transportation, industrial and defence systems).
Video capture configurations
Featuring 4-channel NTSC/PAL/SECAM video decoders with composite video (CVBS) inputs, this modular MPEG-4 encoder provides dedicated hardware and rate control algorithms to produce a high quality MPEG-4 video stream. It can capture video (from PAL/NTSC cameras, VCR, and other video sources) in any of three modes: up to 30 frames/sec on one camera at full screen; up to 30 frames/sec on two cameras at 1/2 screen; or up to 30 frames/sec on four cameras at 1/4 screen. The board also provides an analog video output channel to perform real-time monitoring of the recording sequence.
