IP or analog intercom for prison: The primary purpose of a prison communication intercom system is to facilitate safe and secure movement of staff, visitors and detainees. However, these three groups have their own communication requirements which can be very different from each other.

The visitors want to meet the inmate in a safe and secure environment. The prisoners would prefer an intercom station in their cell that offers music distribution and light control. Finally, the guards want the intercom stations in the cells to be equipped with a scream alarm and light signaling in case of an attack. This means that the intercom itself needs to be rugged and offer a high level of integration with other technologies.

The guards patrolling the facilities want a direct communication link to the control room and the other guards patrolling the corridors. The control room wants to have eyes and ears throughout the entire building and be able to address individual cells or public zones.
