These pages setup the video streaming properties of the VSR. Video streaming is a new concept to many, so we
have included the following overview. A certain level of IP network knowledge is required to properly set up
video streaming.
Streaming Video Overview
Video Streaming is the process that the VSR family, including SymNet and the IP camera use to listen on a
specific UDP/TCP port for control messages and respond to them. The communication over this protocol can
be between a PC application, such as Video Navigator and any of the above products. The UDP/TCP port is
configurable. The default port setting is 8092. IP Multicast is also supported.
IP Multicast
IP multicast is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single
stream of information to thousands of recipients. IP Multicast delivers source traffic to multiple receivers
without adding any additional burden on the source or the receivers while using the least network bandwidth of
any competing technology. High-bandwidth applications, such as MPEG video, may require a large portion of
the available network bandwidth for a single stream.
Note:
Configured incorrectly IP multicast can become a serious drain on your networks resources! If you are at all uncertain
on how to setup IP multicast, please contact your network administrator or IS professional.
The Internet Assigned Numbers Authority (IANA) controls the assignment of IP multicast addresses. It has
assigned the Class D address space to be used for IP multicast. This means that all IP multicast group addresses
will fall in the range of 224.0.0.0 to 239.255.255.255. This address range is only used for the group address or
destination address of IP multicast traffic. The source address for multicast video is always the source or
senders IP address.
