ETS SM1-TRCF Compact Vandal Resistant Surface Mount Omni-Directional Microphone

ETS SM1-TRCF Compact Vandal Resistant Surface Mount Omni-Directional Microphone

High performance, omni-directional ruggedized, pre-amplified microphone for use in low profile applications where tamper resistance is required. Ideal for vehicular interior applications. Small form factor microphone and pre-amplifier circuit board. 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 quipment.

The SM1-TRCF is designed for indoor applications and surface mounted on any flat surface using the supplied tamper resistant screws. Do not mount the microphone near air conditioning vents, light fixtures or electrical equipment. The SM1-TRWCF should be placed as close as possible to the subject of interest. The SM1-TRWCF is useable in the range of 3-25 feet but is dependent on the level of background noise in the area. Experimentation in the environment will determine what distances work best.
