A multi-channel, PCI-bus, wavelet
video compression board.
Overview
DVA XPress Plus is a low-cost, PCI-bus, video capture and compression
engine that combines the capabilities of fast video switching, digital
video recording and viewing of video from up to eight cameras simultaneously.
Video can be switched, controlled, digitized, stored, recorded and
played back in a variety of flexible options.
8 Camera Inputs
Up to eight cameras can be configured and switched with DVA XPress
Plus. Any combination of colour or monochrome cameras can be configured.
DVA XPress Plus supports both NTSC and PAL standards.
High-Quality Wavelet
Video Compression
DVA XPress Plus utilizes wavelet video compression, which offers
improved quality at high compression rates.
Video Display Options
Video can be displayed full-screen on an analog video monitor and
in a resizable video window on your VGA monitor.
Video Output
Video can be displayed on a separate monitor or recorded to a VCR.
Programmable Control
DVA XPress Plus provides programmable control to trigger video surveillance
on alarm or event, to initiate a preprogrammed video sequence or
to control manual video observation. DVA XPress Plus can be programmed
to prioritize critical viewing areas.
Activity Detection
Activity detection prioritizes and controls the rate of camera sequence
recording, viewing and digital capture of important camera scenes
-- an invaluable capability -- by responding to movement.
Alarm Triggers
Up to eight input triggers provide alarm or event verification for
each camera assigned to a trigger. Triggers can be activated by
a variety of input devices including sensors, motion detectors,
proximity switches and contact closures. Triggers can be configured
to control the preferred video display option, digitally capture
and save the video image, and activate external events. An output
trigger provides activation of audio or visual alarms or time lapse
recording.
Capturing, Storing and
Printing Images
DVA XPress Plus is also a full-featured PCI frame grabber. Full
colour or monochrome video images can be digitally captured and
saved in your PC in a variety of file formats including BMP, TIFF,
JPEG and more. Images can be copied into MS Windows applications,
included in reports, and printed.
Extensive Software Support
DVA XPress Plus comes complete with full support for MS Windows
95, 98 and NT. The included XVCR software application (pictured)
allows for full control of capture, compression and playback of
all eight video inputs. An optional Software Developers Kit offers
developers and integrators the flexibility to develop custom applications.
Full Compatibility
The DVA XPress family is fully compatible with the latest generation
of Pentium II computers.
Cost Effective
DVA XPress Plus turns your computer into a powerful CCTV surveillance
system or digital time-lapse recorder for an exceptionally low cost.
DVA XPress Plus protects the investment of existing surveillance
systems by using most of their components, including cameras, monitors
and cables.
