Digital Ally’s VoiceVault Advanced Wireless Microphone includes several industry-first features, such as on-board solid state memory that records audio evidence when going out of range or the signal is interrupted. It offers range of up to one mile by adjusting the transmit power as the range increases. Using an ear-piece with the wireless microphone allows officers to communicate with each other or listen to suspects inside the vehicle. It also includes an integrated GPS with “mark” feature and embeds coordinates plus date/time stamp. An emergency call feature even sends a “help” message and GPS coordinates back to the vehicle.
