1 Introduction The PCI-MP4S is a MPEG4 software video compression development kit that combines excellent real-time image acquisition and advanced MPEG4 software video compression algorithm for security and remote video surveillance applications. This 32-bit, 33MHz PCI bus frame grabber simultaneously captures four video analog streams in real time. It accepts standard composite color (PAL, NTSC) or monochrome video format (CCIR, EIA) camera input.

Bitrate = Highest 2 1024000*4 frame_rate = 30 Bitrate = 1024000 frame_rate = 30 Bitrate = 1024000/4 frame_rate = 30 Supports setting of initial motion detection area and assigning or creating directory for saved files. Save video file: Supports save continued video to M4V or AVI video file format. User may play AVI file with MS Media Player after installing XVID CODEC (see ADLINK All-in-One CD). Save single image file: Supports save single image to BMP or JPEG image file format. 1.1.
programmable inactivity time-out. This ensures reliable operation of remote systems. 1.1. 7 I/O Lines The PCI-MP4S is fitted with TTL compatible I/O lines protected against overloads and electrostatic discharges. Each line may be configured for input or output. They can be used to trigger acquisitions or to report alarm signals. 1.1.8 Supported software WDM driver - supports VC++/VB/BCB/Delphi programming under Windows NT/98/2000/XP platforms with DLL.
