PHYSICAL SECURITY SYSTEM HAVING MULTIPLE SERVER NODES

A physical security system having multiple server nodes may be built as a distributed network. To send data between the nodes in the network, a first node may access a node identifier identifying a second node, with both the first and second nodes forming at least part of a server cluster, and the first node may then send the data to the second node. The node identifier forms at least part of cluster membership information identifying all and accessible by all server nodes in that server cluster. Functionality such as the ability to share views between system users and the ability for those users to control an unattended display may be implemented on a distributed network, a federated network, or another type of network.
