The 615 is a Legacy product and is not recommended for new designs. The lead time for the 615 may be as long as 12 weeks and may require a minimum quantity order. Please call for availability.
Description
Model 615 JPEG Frame Grabber captures images from its sixteen inputs and performs hardware JPEG compression.
The video source can be from non-synchronized cameras. Interlaced frames are buffered before compression. Scaled down uncompressed images are available for visual monitoring and for motion detection by the host computer. The 615’s overall throughput is 30 frames/sec for NTSC and 25 frames/sec for PAL.
The 615 implements a 16 x 4 crosspoint video switch and uses 4 separate decoders with individual frame buffers. This allows cycling through all 16 input channels at the full capture rate without losing frames during channel switching.
Input Clamping
Each input channel has a clamping circuit to minimize the effects of switching from one floating camera signal to another. Image artifacts from a previous channel will not affect the current channel.
Caption Overlay
A text caption buffer (64 characters), modified on a frame-to-frame basis, may be overlaid on the compressed image. The position of the caption, character size and color are software controlled. The caption is transparent, i.e. only the characters overlay the image. Caption formatting functions available in the software provide an easy way of including date and time stamps.
Compression
Model 615 executes the baseline JPEG compression with the software controlled compression factor.
The minimum compression factor results in the image file size of about 50KB for a full resolution NTSC frame. Increasing the compression factor yields smaller files at the expense of image quality.
Frame rates
Each of the four decoders digitizes 30 frames per second to give an overall board throughput of 30 fps for 640 x 480 interlaced frames. These throughputs include JPEG compression. If all sixteen channels are used the frame rate per channel is 1.8 fps.

Hardware compression
Model 615 executes hardware JPEG compression to greatly reduce the amount of memory needed to store images. Hardware compression reduces the CPU and PCI bus loading.
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. Please see 817TA installation diagram.
Termination Boxes
The 615 may be connected to optional termination boxes (listed below) with a flat cable, Model 609C1.
Model 609TA-ND provides sixteen BNC’s for inputs and eight BNC’s for video output. Also requires cable 609C2.
Model 609TA provides sixteen BNC’s for inputs, eight BNC’s for video output and captive terminals for the digital I/O signals.Also requires cable 609C2.
Model 609TB optional termination box supports 32 cameras. Also requires Cable 7409C1 and 609C5
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.
