Video Encoding and Transport
The Harris® Intraplex® NX-AVC-1 video encoder module represents the latest standards-based technology for low bit rate video transport. The module can encode an incoming analog NTSC or PAL signal to H.264 (MPEG-4 Part 10 AVC), MPEG-4, or Motion JPEG (MJPEG) for distribution across IP networks. The highly efficient H.264 standard offers an excellent combination of video quality, bandwidth reduction and cost savings.
The NX-AVC-1 plug-in module is compatible with the Harris Intraplex NetXpress™ IP multiplexer. This allows for integration of video streaming and analytics alarms into end user video, audio, data and voice networks. Compatibility with the NetXpress platform provides a common management control interface, scalability, and application flexibility for a superior managed solution. The NX-AVC-1 module, used in conjunction with the NX-MIU-801 module interface unit, provides video and audio connections to external equipment. Standards-based video encoding allows integration of NetXpress™ with compliant third party software applications.
Optional Video Analytics
Video analytics capability is an option for the NX-AVC-1 module. Video analytics is an automated tool for monitoring activity in the camera view and generating alarms based on user-defined criteria. The ability of the analytics toolset to identify persons and vehicles and to recognize violations is an invaluable asset in surveillance applications. This capability transforms a passive surveillance monitoring activity into a proactive, efficient system.
