Interoperability is the ability for agencies to communicate while responding to mutual aid incidents. This means connecting not only radio transmissions, but also connecting disparate video systems in order to share visual informaiton in real time. By using an everything-over-IP peer-to-peer architecture, disparate audio and video systems are able to connect. For example, school walkie-talkies can communicate with Motorola police radios. And school can share video from any camera or video management system with law enforcement on an as-needed basis. Our solution includes cloud-based and hardware interoperability components.
