The digital video surveillance system generally contains:

1. Servers – hardware Servers—hardware and program software platforms used to receive and process video and audio signals from analog and IP surveillance cameras.
2. Remote Admin Workstations – hardware Workstations—hardware and program software platforms used for remote administering administration of the video surveillance system and as the specialized platforms for : video gateway, remote archive server, remote web server etc, and so on.
3. Remote Client – hardware Client—hardware and program software platforms used as Operator’s operator’s workstations to realize implement remote video surveillance and audio monitoring.

Servers, Remote Admin Workstations and Remote Clients are integrated into the video surveillance system, fitting the system's set of functions, safety requirements, specific features of the guarded location etcprotected location, and so on. The video surveillance system may can include several subnets, subnetworks that interact via selected (node) servers and Remote Admin Administrator Workstations. The distributed architecture of the video surveillance system provides synchro synchronized data exchange (events, commands, setting parameters, etcand so on) among its components.

Servers, RAWs, and ROWs communicate with each other in via LAN, WAN, VPN, Wireless and wireless networks using the TCP protocol.
