We work with you to create concepts and specifications and translate them into hardware solutions that work. Depending on your specific business need and cost, we produce custom hardware at our production facilities or leverage existing hardware.

No matter the approach, our development team applies their years of customer knowledge and expertise in:

• hardware analysis and design;
• production;
• testing implementation; and
• data communications systems

to create the most reliable, cost-effective solution for you.

Examples:

• Call Box: PURVIS developed an on-the-street call box to enable citizens 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.
• Voice Alarm Line Card Interface: PURVIS created a custom Voice Over Internet Protocol (VoIP) hardware interface between legacy analog hardware and the modernized FDNY Voice Alarm solution. This interface is a cost effective way to update centralized equipment to modern VoIP technology while maintaining a communication path to remote legacy equipment. In this way, PURVIS extends the life of legacy, providing a multi-phased update approach where the cost can be amortized over longer periods. This approach also ensures virtually no down time while system upgrades are being performed.
• Audio Electronics Unit (AEU): This PURVIS-designed custom hardware creates an interface between the dispatcher’s headset, desk-mounted microphone and speakers, call recording equipment and other dispatcher communication devices. The result is seamless voice connectivity between the various devices while maintaining the required call recording features.
