Control Centres

The successful management of central control rooms is absolutely fundamental to any organisation responsible for public security and communication services.

TDM offer extensive experience in installation, relocation and maintenance of control centres.

Operator Terminals - Providing control centre operators with one user-friendly GUI that allows the management of multiple systems ensures the smooth running of the control room.

Evidence - Many control rooms are required to have an evidence gathering facility which relies on a robust recording system for both voice calls and CCTV footage.

The Complete Picture - An integrated system allows the operator to have a complete view of the situation they are dealing with, for example, handling a call from a member of the public whilst watching a live CCTV view of the situation, and knowing the exact location of the caller.

Reliable and Cost Effective - TDM provides an IP-based communication platform that uses the latest technologies to provide fast and reliable communication and to ensure failsafe operation. Providing an interface to existing and legacy systems and technologies allows for the most economical and environmentally suitable solutions to be designed.
