NX-AVC-1 IP Video Module

Video Encoder with Optional Analytics for NetXpress™

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.

Features

  • Video Stream Encoding
    The NX-AVC-1 provides two channels of video encoding. NTSC or PAL signals can be encoded to H.264 Baseline Profile, MPEG-4 Simple Profile or MJPEG video formats. The encoded channels may be unicast or multicast.
  • Compatible with PC Viewers
    PC-based viewers can receive and display video that is encoded on the NXAVC-1. Video encoding parameters, such as bit rate, frame rate and resolution, can be adjusted directly from the PC viewer using RTSP protocol or via the NetXpress browser-based management interface.
  • Video Analytics
    With the addition of the optional video analytics feature, the NX-AVC-1 encodes a single video channel while simultaneously analyzing the video for user-defined security violations. Alarms are broadcast on the network and can be sent via e-mail for notification and response of security personnel. These alerts are logged for later evaluation.
  • Alarm-Driven Video
    Alarms generated by the video analytics tool can temporarily adjust the video parameters to provide improved imaging for security personnel, while working within network bandwidth constraints.
