CCTV Dissemination

Innovative Delivery of Motorway CCTV

The objective of this project is to provide a system which can be used to demonstrate how video clips and live video streams can be delivered from motorway CCTV cameras to clients situated anywhere in the Internet. The project was undertaken as part of the VIH project.

SSL have developed a web front end to deliver the live CCTV images to desktop PCs, laptops or PDA's with a connection to the Internet. Users can select cameras from a list or from a schematic map of the motorway network. If the user has appropriate authentication, it is also possible to control the camera position using this interface. The system is developed to comply fully with the Second Generation CCTV protocols.

Behind the front end, a digital video media server is used to disseminate the video clips and streams over the HTTP and RTSP protocols as MPEG4.

The project has been designed to fit in with the existing VIH system and the future Second Generation CCTV systems with minimum disruption. To achieve this, SSL's Access Control System (ACS) has been extended to include an additional CORBA interface to an Access Control Interface (ACI). The ACI has also been developed by SSL and acts as a gateway to the VIH system allowing cameras to be selected and controlled by VIH Clients.

 

 

 

 

 

SSL have also developed an authentication component called the Highways Video Client Gateway (HVCG) to interact with the ACI. This component is responsible for storing clients' accounts and logging clients in and out of the system.
