DM1-EJ

Covert, RJ45 Ethernet Jack Style Microphone with DSP Background Noise Reduction

Description

ETS DM1-EJ | Covert Line-Level Microphone with Embedded Digital Background Noise Reduction in Cat5

The DM1-EJ is a high-performance, omni-directional microphone with integrated digital signal processing (DSP) for background noise reduction, engineered for fixed-location security and surveillance applications. Housed in a discreet ethernet jack-style wall plate, the DM1-EJ blends seamlessly into modern environments, providing a covert yet powerful audio monitoring solution.

Advanced DSP Technology for Clarity in Noisy Environments

Unlike standard pre-amplified microphones, the DM1-EJ uses embedded DSP technology to digitally filter out repetitive background noise while enhancing human speech clarity. This makes it ideal for high-noise areas such as manufacturing floors, lobbies, retail stores, or transportation hubs.

The microphone’s omni-directional pickup pattern provides a 25′ coverage radius, while adjustable automatic gain control (AGC) and output level settings ensure optimal audio capture in dynamic sound environments. The DM1-EJ also includes a built-in limiter circuit to prevent audio distortion during loud sound events.

Covert, Convenient, and Easy to Install

The DM1-EJ is mounted in a dual ethernet wall plate, with one functioning network jack and one covertly housing the microphone. This design enables seamless installation into standard infrastructure, maintaining discretion without sacrificing performance.

With its advanced digital noise reduction, wide pickup range, and inconspicuous appearance, the DM1-EJ is the ideal solution for security integrators seeking reliable and intelligible audio in challenging acoustic environments.
