The continuous advancement and deepening of prison informatisation, through the application of advanced information technology, has made the digitalisation, intelligentisation, and integration of prison operations a fundamental requirement within prison informatisation development. The establishment of a robust ‘Prison Cell Visual Intercom System’ enables prison officers to monitor detainee conditions and relevant information in real time, effectively controlling and preventing incidents such as altercations, escape attempts, suicides, and other emergencies within cells. Leveraging the existing prison network, a highly efficient, reliable, and stable ‘SIP Network Prison Cell Visual Intercom System’ shall be established.

Configure a visualised broadcast dispatch console and SIP intercom host within the prison monitoring centre as the command system, enabling unified management and real-time monitoring of intelligent terminals across all secure zones within the prison perimeter. Install emergency assistance intercom devices, cameras, and SIP loudspeakers in cells, cell blocks, guard towers, visiting buildings, and public activity areas. During emergencies, the monitoring centre can initiate broadcasts, activate intercom functions, synchronise video surveillance with on-site situations, and conduct real-time monitoring of cells and other areas. Upon security incidents, prison personnel may trigger alarms by pressing emergency terminals, enabling two-way communication with duty rooms or the monitoring centre. This facilitates multi-party consultations for prompt incident resolution.
