Grabbing The Frame | Pleora

  • By Jason Stockwell

Almost written-off by the introduction of new technology, the venerable frame grabber is alive and well. Here we look at some of the major players.


Pleora

Pleora Technologies, which is based in Ottawa, Canada, is one of the world’s leading supplier of highperformance video interfaces. It has introduced the imaging market’s first external frame grabber that helps manufacturers and system integrators reduce costs, simplify cabling, and speed time-to-market by converting Sony FCB-EV7520A block cameras into GigE Vision 2.0 cameras.

“The iPORT SB-GigE-EV7520A builds on our extensive expertise in developing video interfaces for Sony block cameras,” said Harry Page, President, Pleora Technologies. “Our new external frame grabber gives manufacturers and integrators a low-risk way to leverage the design, cost, and performance benefits of Ethernet when deploying Sony’s high-sensitivity, high-quality block camera in high-performance imaging applications.”

Pleora’s external frame grabbers for block cameras have been designed into a wide range of imaging applications, including medical telepresence, perimeter security, transportation, robotics, sports analysis, and drone systems. The iPORT SB-GigE-EV7520A transmits video with low, consistent latency at high frame rates between the Sony block camera and computing platforms or displays. Video, power, and control data is transmitted over low-cost Ethernet cabling to existing ports on the computer or display. Designers can choose from a broad selection of small form factor and low-power computing platforms, including laptops and embedded systems.

The networking flexibility of GigE means images from multiple Sony block cameras can be aggregated to a single port, and/or images from one Sony block camera can be multicast to multiple PCs and displays. With the extended reach of GigE – up to 100 meters over standard Cat5e/6 cabling and further with basic network switching – image analysis equipment can be centralized in a remote location.

In comparison, competing Sony block video interfaces require multiple cables for video transmission and control, external power sources for cameras, and PCIe frame grabbers to capture images at the PC or display. This results in more complex systems, longer design times, higher costs, and limited component selection.
