New Audio and Video Capture Card Targets Developers of Mobile Streaming and Surveillance Applications

DALLAS � Feb. 15, 2005 � ViewCast Corporation (OTCBB:VCST - News), today announced the release of the Osprey-440 audio and video capture card. The Osprey-440 leverages the capabilities of the industry-leading Osprey video capture cards and enhances performance levels by supporting four independent A/V channels and allowing the use of up to 16 cameras or other video sources. The Osprey-440 meets the expanding requirements of mobile streaming service providers, developers of military and law enforcement video systems for training and surveillance and purveyors seeking high-capture channel density.

With a single Osprey-440 card, systems integrators, OEMs and developers have access to four independent A/V processing channels increasing audio and video channel density required for large video systems installations while dramatically reducing overall systems cost.

Four external BNC connectors are available on the Osprey-440 for analog composite video input, with each connected to a dedicated capture channel. Twelve additional auxiliary inputs are available on an internal pin-field connector that can be used as alternatives to the rear panel connectors. This feature gives developers the option to internally connect audio and video to the Osprey-440 for a cleaner and more flexible system design.

Users can connect up to 16 cameras or other video sources to a single card and use software to switch between them, as needed for surveillance applications that require monitoring of multiple feeds. Alarm relays on each channel can activate a user-defined event as determined by the user's applications, for example, motion is detected, a light flashes, and a camera switches on to start capturing movement at 30 frames per second. The Osprey-440 also provides four channels of stereo audio allowing capture of synchronized audio with video.
