Simply connect the microphone to a DVR, audio recorder, or monitor for listening at any time. The microphone has a recording range of up to 25 feet, which will cover a large room.

The microphone features a low noise MOSFET pre-amplifier for hard to hear audio. The gain can be easily adjusted for clarified, crisp audio.

The interface adapter is reverse polarity protected and fused, so no need to worry about shortcomings. It is also equipped with an LED indicator.
