Activate UDP connectionwhen occasions require time-sensitive responses and the video quality is less important Note that eachunicast client connecting to the server takes up additional bandwidth and the Network Camera allows upto ten simultaneous accessesUDP multicast: This protocol allows multicast-enabled routers to forward network packets to all clientsrequesting streaming media This helps to reduce the network transmission load of the Network Camerawhile serving multiple clients at the same time Note that to utilize this feature, the Network Camera mustbe configured to enable multicast streaming at the same time For more information, please refer toRTSP Streaming on page 60TCP: This protocol guarantees the complete delivery of streaming data and thus provides better videoquality The downside of this protocol is that its real-time effect is not as good as that of using the UDPprotocolHTTP: This protocol allows the same quality as TCP protocol without needing to open specific ports forstreaming under some network environments. Users behind a firewall can utilize this protocol to allowcamera’s streaming data to pass through26 - User's Manual
