Description
The SM1-EJ from ETS is a High performance, Omni-directional, pre-amplified microphone for fixed location security applications. Dual Ethernet jack wall plate features one working Ethernet jack and a microphone in the other. 25’ pickup pattern in all directions. Built in limiter circuit automatically lowers the output level during loud sound intervals. Selectable lo-cut and hi-cut filters significantly reduce background noise. Connects directly to our switcher / mixer / amplifiers or use one of our many interface products to make fast and clean connections to DVRs or remote monitoring equipment.
