  • 4 NTSC/PAL composite/S-Video + 4 stereo audio inputs
  • Simultaneously captures multiple channels
  • RGB, YUV video formats
  • VB1 support
  • 4 GPIOs

Model 911 is a PCI/104-Express board that simultaneously captures four channels of analog video and four channels of stereo audio. It captures raw video frames from each channel at up to full frame rate, resulting in an aggregate frame capture rate of up to 120 fps for NTSC and 100 fps for PAL. The 911's high frame capture rate, coupled with its high performance bus interface, makes it well-suited for applications that require uncompromising capturing of multiple video sources in a compact form factor.

A 24-pin header provides convenient access to all I/O signals on the board. This enables all of the board's I/O signals to be routed through a single cable to a custom termination system or to one of Sensoray's standard breakout boards (see Accessories).

The board's PCI/104-Express connectors support both stack-up and stack-down so that the board can be located anywhere in the stack, and its full conformance to the PCI/104-Express specification guarantees that it won't mechanically interfere with adjacent boards.

All operating power is obtained from the PCI/104-Express bus; no external power supply is needed.

Each of the four video inputs may be connected to a composite or S-video source, or left unconnected if not used. The unit supports a wide range of video capture resolutions, including D1, VGA, QVGA, QQVGA, SIF, 2SIF, 4SIF, CIF, QCIF, SQCIF, and 4CIF. Captured frames are formatted as raw RGB or YUV.

Digital I/Os
Four general-purpose digital I/O (DIO) signals are provided for controlling cameras and illumination sources, alarm signal monitoring, etc. The DIOs may be configured to function as all outputs or all inputs.

Software Development Kits (SDKs) are available for both Linux and Windows developers. The SDKs include drivers, programming examples, and comprehensive documentation to enable programmers to quickly develop custom application software for the 911.

System Requirements
Due to the extremely high data rates involved, a computer with sufficient bandwidth and processing power is required to ensure error-free processing of the video streams produced by Model 911. SENSORAY has tested Model 911 with a cross-section of computers to help you determine whether your system will support these high data rates. For details see 911 Performance Benchmarks.

Qualified computers
Single-board computers (SBCs) are a great way to take advantage of the 911's compact size and advanced capabilities. SENSORAY is continually testing new SBCs; qualified units are listed at 911 Verified SBCs.

SENSORAY offers several breakout boards that route the 911's video, audio and digital I/O signals to standard connectors. All of the breakout boards are designed to directly connect to the 911's 24-pin I/O header with a single cable.

Model 811TA-SVIDEO breaks out all of the 911's video inputs and digital I/O signals. It has four S-Video input connectors and a spring terminal block for digital I/Os.
