Model 817 combines the functions of a frame grabber, hardware JPEG encoder, and 16 X 4 video crosspoint switch, into a PCI-express (x1) card. It is capable of capturing full resolution color JPEG-compressed images and / or monochrome uncompressed bitmaps, from 16 channels at full NTSC or PAL frame rates.

Frame rate
Four identical video capture and processing units (VCPU) work together to compress JPEG images at 30fps on all 16 channels simultaneously for a total board throughput of 480 fps for 640 X 480 interlaced frames.

Hardware compression
Model 817 executes hardware JPEG compression to reduce the amount of disk space required to store images. Hardware compression greatly reduces the load on the CPU.

Multiple boards
Sensoray's driver supports multiple 817's in the same computer.

Real-time outputs
A 16x4 analog crosspoint video switch is used to route any combination of four input channels to external video monitors. Each of the four video outputs can be individually turned on or off, which allows connecting the outputs of multiple 817’s to the same monitor.

Text Overlay
An optional single line text caption (up to 80 characters) can be overlaid on the captured images (before compression).

Deinterlacing
Model 817 performs optional deinterlacing of interlaced video to reduce motion artifacts on captured images. The lines of one of the fields of video are recreated from those of another field by using interpolation. This method provides better visual quality compared to simple line doubling. Since the deinterlacing is performed by the firmware running on the DSPs, it slows the capture rate down slightly.

Model 817TA Distribution Amplifier
Model 817TA is an indispensable tool for application development and troubleshooting with Sensoray’s 16-channel frame grabbers (models 615, 617 and 817). Model 817TA takes one standard composite TV video signal (BNC connector) and splits it into 16 buffered outputs of standard amplitude and impedance. The outputs are connected to a 34-pin ribbon cable connector standard for above mentioned frame grabbers. A combination of models 817TA and 609TC, TE or TG yields a splitter with 16 BNC outputs.

Termination Boxes
A termination box is recommended for interfacing the video signal to the Model 817.
Sensoray offers the following termination boxes. A flat cable, Model 609C1 (video in) is needed.

Model 609TA-ND provides sixteen BNC’s for inputs and eight BNC’s for video output. Also requires cable 609C2 (video out) and 7409C1 (digital I/O) .

Model 609TC provides 16 BNC's for camera connections and is 2U height.
Model 609TE provides 16 BNC’s for camera connections and fits in the space of a CD player.
Model 609TG supports 32 camera connections and is 2U height for 19” enclosure.
