Figure 1 displays the TCSS (Transport Camera Security System) overview. The '802.11 a' wireless LAN protocol has the capacity for high speed data transmission up to 54 Mbps. With careful planning, receiver Access points can be spaced up to as far as one kilometre apart. This system provides seamless handover between Access points at rated speeds. Anywhere up to around 30 cameras may be transmitting simultaneously within the common Access Point Range.

This application is ideally suited to operate over fibre optic network where immunity to external sources is required and where new value added features can readily be accommodated as the system evolves and the technology develops, such as VoIP for example.

Figure 2 displays the general mobile station interconnection diagram. The number of cameras can vary on requirements. In this application, 470 line colour cameras were used with auto focus, auto iris, and remote control audio as standard features.

The MPEG -4 compression provides the latest technology in data compression protocols and most efficient bandwidth utilisation and recording quality. Up to 25 FPS (Frames per second) for each camera is scheduled for the transport fleet implementation.

OSA (Open Systems Architecture) philosophies are essential in supporting the long-term sustainability of this major system. All information processing and data manipulations perform on proven robust, Industry standard Operating Systems.
