Scenario Replay is a fast, flexible and easy-to-use search and replay tool combining simple searching along with complex scenario reconstruction capabilities to improve how voice recordings are used in public safety. Scenario Replay, from NICE Systems, was designed as a multiple-channel synchronous replay application and further enhanced to provide quicker searches and identification of radio transmissions by PTT-ID, aliasing, talkgroup ID and radio ID. It provides the tools needed to recreate complex scenarios that occur, including radio transmissions replayed along-side telephone calls. Scenario Replay provides convenient and fast access to voice recordings on all recorders and channels in the system, which then can be analyzed and sorted quickly and efficiently to give the complete picture of an incident.
