3.3 Overview of Functions
Network Video Encoder
The VIP X1600 XFM4 encoder module is a network video server for up to four independent
video channels. It is primarily designed for encoding video and control data for transfer over
an IP network. Audio signals can also be transmitted to compatible units. The use of existing
networks means that integration with CCTV systems or local networks can be achieved
quickly and easily. The module offers the complete resolution of 4CIF on both streams of all
four of the channels, at the complete image rate of 25 (PAL) or 30 (NTSC) images per second.
Video images from a single sender can be received simultaneously on multiple receivers.
The encoder module VIP X1600 XFM4 is designed for installation in the VIP X1600 XF base
system. Installing the units is a quick and easy operation that does not require any additional
tools. All modules are hot swappable and can be exchanged while the system is running.
Receiver
Compatible H.264-enabled hardware decoders can be used as receivers, for example VIP XD.
Computers with decoding software such as VIDOS or computers with the Microsoft Internet
Explorer Web browser can also be used as receivers.
Video Encoding
The VIP X1600 XFM4 encoder module uses the H.264 video compression standard. Thanks to
efficient encoding, the data rate remains low even with high image quality and can also be
adapted to local conditions within wide limits.
Dual Streaming
Dual Streaming allows the incoming data stream to be encoded simultaneously according to
two different, individually customized profiles. This feature creates two data streams that can
serve different purposes, for example one for recording and one optimized for live
transmission over the LAN.
Multicast
In suitably configured networks, the multicast function enables simultaneous real-time video
transmission to multiple receivers. The UDP and IGMP V2 protocols must be implemented on
the network for this function.
Encryption
The VIP X1600 XFM4 encoder module offers a variety of options for protection against
unauthorized reading. Web browser connections can be protected using HTTPS. You can
protect the control channels via the SSL encryption protocol. With an additional license, the
user data itself can be encrypted.
Remote Control
For remote control of external units such as pan or tilt heads for cameras or motorized zoom
lenses, control data is transmitted via the module's bidirectional serial interface. This
interface can also be used to transmit transparent data.
In the VIP-X1600-XFM4B variant the encoder module also supports Bilinx technology, which
permits bidirectional communication over the video cable for control of Bilinx-compatible
units (such as AutoDome and Dinion cameras) and allows access to their data.
Tamper detection and motion detectors
The VIP X1600 XFM4 encoder module offers a wide range of configuration options for alarm
signaling in the event of tampering with the connected camera. The parts included also
comprise an algorithm for detecting movement in the video image and this can optionally be
extended to include special video analysis algorithms.
