Server

The server-centric architecture has been designed to simplify the setup and management of surveillance systems whilst maximising the visual quality of the real-time video by avoiding unnecessary transmission.

• Each encoder provides a single media stream to a Server which in turn provides that stream to multiple clients. This is in sharp contrast to traditional point to point architectures which require a separate stream to be served from an Encoder to each client with a corresponding drop in visual quality each time a new client connects due to the sharing of the physical channel.
• TVI has been optimised for operation over wireless including GPRS/UMTS/HSDPA and the server-centric architecture removes the need for fixed SIMs giving simpler deployment and reduced data costs. Any point to point system requires deployment with fixed SIMs.
• Setup and management of multiple Encoders is simplified through the use of DHCP. Only the Server needs a fixed IP address. Once connected to a Server, the configuration of an Encoder is done via the Server as is the requesting and forwarding of media streams. Thus a client needs only the Server address to access any of the connected Encoders.
• The Server provides access management including setting individual client and client group rights to access streams, taking PTZ control of connected cameras, modifying coding parameters, and where available, accessing archived media.
• All live and archived media accesses are logged to identify the client, the source, time, and date in order to comply with data protection regulations.
