Example of the Axxon PSIM distributed system structure

When you create the distributed video surveillance system structure, you must take into account:

1. The number of servers, remote administrator workstations, and remote clients that must be installed on the protected facility.
2. The distances between video surveillance system components and the capacity of their communication channels. For example, servers are divided by long stretches of land; remote administrator workstations and remote clients are within the same room—the central surveillance station. Considering engineering constraints, servers will have the low-capacity channels, and remote administrator workstations and remote clients will have high-capacity channels. Then remote administrator workstations and remote clients interact with servers via the gateway only.
3. The system security requirements, for example, that prevent unauthorized administering are separated for subnetworks with servers and remote administrator workstations and subnetworks with remote clients. Subnetworks interact via the gateway only.

An example of the organization of the distributed video surveillance system is shown in the figure.
