摘要

A real-time image monitoring and recording system includes a plurality of IP cameras and a plurality of surveillance servers. The IP cameras and the surveillance servers can process anycast packets. The surveillance servers control the IP cameras and store data generated by the IP cameras. Peer-to-peer connection exists between the surveillance server and its neighboring surveillance servers. Any surveillance server stores configuration data of its neighboring surveillance servers rather than the configuration data of all the surveillance servers.
