Description
Model 617-4 combines the functions of a frame grabber, hardware JPEG compression and digital I/O into one PCI board.

The 617-4 accepts four composite video inputs and routes to separate video decoders for digitizing.
The use of four decoders eliminates losing frames during channel switching.

Frame rates
As long as there is just one JPEG compression engine on the 617-4
The capture rate is 30 fps at 640x480 resolution (25 for PAL) or 7.5 fps per channel, if all channels are used.
At 320x240 resolution, the capture rate is 120 fps (100 for PAL) or 30 fps per channel.

Hardware compression
Model 617-4 executes hardware JPEG compression to greatly reduce the amount of memory needed to store images.
Hardware compression reduces the CPU and PCI bus loading.

Multiple boards
Sensorayís software supports multiple 617-4ís in the same PCI bus.
For example, two 617-4ís may be used to expand the number of video inputs to eight.

Real-time outputs
Four video inputs are routed to four output channels for display on video monitors.
A software-selectable switch after each buffer amplifier allows multiple 617-4ís to share the same video monitor.

Text overlay
The 617-4ís caption buffer allows overlaying text on each frame.
The text is within a transparent box that may be positioned in one of 4 possible locations of the frame. The text size and color are programmable.

Special output
The 617-4 also supplies small-size uncompressed frames suitable for motion detection by the host computer.
These are 128 x 96 pixels or 256 x 192.

Software and Manuals
The 617-4 is supplied with a software developerís kit, SDK17. It includes drivers for Windows 98/NT/2000/XP.
A Linux driver for kernel 2.4.10 is available. Each kit includes sample application programs.
