Revision A 

Introduction 

This is the user guide for the WatchGuard Video Long Range Transmitter 

(LRT) Wireless Microphone.  The LRT Microphone is a specialized 

device designed to be used exclusively with WatchGuard’s family of 

vehicle-based digital video recorder (DVR) products.  This Guide’s 

purpose is to describe the proper connection, installation and use of the 

LRT Microphone. 

General Operation 

The LRT connects directly to all WatchGuard DVR products to supply 

one of the audio tracks during the video recording process.  The LRT 

microphone is a system with two primary devices; the Transmitter and the 

Base.  Typically, the user (for example, a police officer) will wear the 

Transmitter device on their body.  This device can be attached to the user 

with one of the available spring-loaded clips or worn in a holster on the 

user’s belt.  Like the DVR, the LRT Base device mounts in a vehicle using 

one of several brackets and attaches to the DVR using a cable.  The Base 

device also requires an antenna connection to provide the wireless radio 

link to the Transmitter device.  This antenna is supplied as part of the LRT 

microphone system and mounts to the vehicle windshield using an 

adhesive.
