System description:
The DVM-900 wireless microphone system operates as part of Digital Ally’s in-car DVR
(digital video recorder) system.
The DVM-900 wireless microphone system consists of 2 transceivers. The first transceiver,
called the In-Car Transceiver (DVM-ICT), is mounted inside the DVM.
The second transceiver, called the Remote Transceiver (DVM-RMT), is carried by the
patrolman either on his belt or lapel. The Remote Transceiver is a self-contained unit,
which includes an internal microphone, external microphone/charge jack, battery charge
terminals, internal rechargeable battery, internal antenna, and 2 buttons for Standby/Off
and Transmit Record On/Off.
The system operates in the 900 MHz ISM (Instrument Scientific Medical) band and is
license free. The system range is 1000 feet. The DVM-900 wireless microphone system
uses Frequency Hopping Spread Spectrum (FHSS) Narrow Band FM, which provides
excellent privacy, security and avoidance of interference.
In-Car Transceiver Model Number DVM-ICT
Operating Instructions:
During setup of the DVR, the operator shall program the In-Car Transceiver. The Remote
Transceiver security
codes shall also be programmed at DVR setup time by sending the
command to SYNC from the DVR to the In-Car Transceiver via the SPI bus. The In-Car
Transceiver will then automatically exchange security information with up to two nearby
Remote Transceivers that are in ready to SYNC mode.
