Introduction
Axon Signal Vehicle is part of a communications platform that, when certain hardware is activated, transmits a message recognizable by Axon Signal compatible equipment. For example, when the vehicle light bar is activated, Axon Signal Vehicle can signal all properly equipped Axon systems within range to begin recording.
Axon systems that work with Axon Signal Vehicle include the Axon Body 2 Camera, Axon Flex 2 system, Axon Fleet 2 system, and all later versions.
