Application Note: NexLog Recording for Harris P25

Solution Overview:

Eventide IP-based voice logging systems provide archival and instant recall recording for the Harris VIDA P25 trunked radio system. IP audio and call-related metadata are reliably captured and archived.  Recordings are instantly available for replay, research, incident reconstruction and export. The same NexLog recording system can also record 9-1-1 and NG9-1-1 interactions, administrative telephones and PC screens.

The NexLog integration with version SR10A2 and later also allows capture of GPS location data associated with P25 transmissions from GPS-equipped Harris P25 radios. The captured GPS coordinates for transmissions can be searchable and available for display on a map using Eventide MediaWorks Plus software.
