PCIe video capture card supports Linux apps

Nov 1, 2007 — by Eric Brown — from the LinuxDevices Archive — 62 views

Adlink Technology has introduced a PCI Express video capture card aimed at surveillance and machine-vision applications. The PCIe-RTV24 is said to capture and display four channels of video at rates up to 30fps per channel, and is available with Linux support.

The PCIe-RTV24 can display four simultaneous screens of live color and monochrome digital video. Adlink says the board is designed for machine vision, surveillance, medical and scientific research, biometric face recognition, and vehicle license plate identification. It can be used for applications such as building surveillance, and can also be used as a framegrabber to digitize still photos, as is often required in manufacturing testing applications or scientific research.

A system equipped with multiple PCIe-RTV24 boards can capture up to 16 channels of video input in standard formats. The board's digital outputs adhere to formats that are typically used in machine vision, security, and video surveillance applications, according to Adlink. The board is also said to be equipped with a separate set of four digital input/output “watchdog” signals that can be used to automatically trigger strobe lights or alarm signals.

Adlink supports the PCIe-RTV24 on both Windows and Linux. The company says the board is compatible with Video4Linux (V4L), a video capture API (application programming interface) for Linux; Microsoft's DirectX multimedia API; and machine-vision video interfaces for National Instruments's Labview virtual instrumentation tool. Additionally, developers can create custom applications using Visual C++, Visual Basic, C++ builder, or Delphi.


The PCIe-RTV24 is available now and priced at $195, with volume discounts available. Further details on the card are available here.
