The PURVIS on-the-street call box enables a citizen to access the police department (911) and fire department over a private communication infrastructure.
When an individual activates the Call Box, an alarm is sent to the appropriate dispatch location and voice communications are established between the dispatcher and the remote Call Box. The dispatcher knows instantly the location of the Call Box and can send appropriate emergency response personnel. PURVIS has modernized the Call Boxes and maintains the back-end infrastructure and wiring as well as the boxes themselves.
