Multicast allows for one-to-many or many-to-many transmission of data to a group of destination computers simultaneously. Using PTZOptics NDI-enabled multicast cameras requires a multicast-enabled network with switches and cabling that support multicast, as well as network-attached devices that are multicast-enabled and have mDNS enabled. IGMP snooping allows network switches to listen to IGMP traffic and maintain maps of which links require which multicast streams to filter traffic to only ports that need it. This allows practical applications like broadcasting customized live streams from the same cameras to different computers for multiple languages or audiences.
![Wikipedia Definition
In computer networking, multicast is group communication[1]
where data transmission is addressed to a group of
destination computers simultaneously. Multicast can be one-
to-many or many-to-many distribution.[2] Multicast should not
be confused with physical layer point-to-multipoint
communication.](https://image.slidesharecdn.com/multicastvideoforlivestreaming-180103181814/85/Multicast-video-for-live-streaming-2-320.jpg)

- 3. Unicast vs Multicast Think on-demand video vs live broadcast channels on your television. (if you haven’t cut the cord already :)
- 4. Requirements for Multicast & NDI Cameras 1. Multicast Enabled Network 2. Network Switch w/ Multicast Capabilities 3. Network with mDNS Enabled 4. CAT5e or better ethernet cabling
- 5. Enabling Multicast and IGMP Snooping Unifi Network Setup.
- 6. What is IGMP Snooping? IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic. The feature allows a network switch to listen in on the IGMP conversation between hosts and routers. By listening to these conversations the switch maintains a map of which links need which IP multicast streams. Multicasts may be filtered from the links which do not need them and thus controls which ports receive specific multicast traffic.
