Network bandwidth can be a concern for some surveillance systems. While improvements in video codecs, such as smart codecs for H.264 and H.265, have reduced bandwidth needs significantly, large systems still encounter issues with large amounts of video data and viewers. In this note, we look at the basics of multicast networks, a frequently-mentioned means of reducing bandwidth, where they will save bandwidth and where they will not.
Inside we explain:
- The Basics of Multicast
- Use in Surveillance
- Unicast / Mulitcast Combinations
- Network Support
- VMS Suppport
- Quiz Yourself: 5 Question Quiz to measure knowledge of Multicast for Surveillance
