Selecting the structure of the distributed system

While designing the distributed video surveillance system structure you should take into account:

1. The number of servers, Remote Admin Workstations and Remote Monitoring Workstations to be installed on the guarded location.
2. The distances between video surveillance system components and their comminication channels capacity. For example, servers are divided by long stretches of land, and the Remote Admin Workstation and Remote Monitoring Workstation are within the same room – the central surveillance station. Given the engineering constraints, servers will have the low capacity channels, and the Remote Admin Workstation and Remote Monitoring Workstation will have high capacity channels. Then Remote Admin Workstation and Remote Monitoring Workstation will interact with the servers via the gateway only.
3. The system security requirements, for example, to prevent unauthorized administering, subnets with servers and Remote Admin Workstations and subnets with Remote Monitoring Workstations, are separated. Subnets interact via the gateway only.

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