c. Accordingly, a high data rate must be delivered by each building CCTV network, to be able to support:1) IP video streaming systems with broadcast and multicast data flow.2) High data-rate systems such as push-and-pull to existing Airport Video Management Servers and Storage-Area Network systems.3) Traffic peaks linked to event-related activities or to a CCTV network device or link failure.d. Accordingly, the CCTV network must provide data-processing priorities, to be able to support low-latency systems such as IP streaming system or security systems.e. Accordingly, the CCTV network must support virtual networks to be able to drive all data flow from several networks in the same physical pipe.f. Accordingly, the CCTV network must support modular access to networks, to be able to integrate any user or IP device in accordance with:1) The type of device connected2) User access rights3) The access mode used by the device4) The Layer level of access control to networks that can be supported on Layers 1 to 7 of the OSI (Open System Interconnection) model.
