ETS SM1-CF Remote Element Covert Surveillance Microphone

The ETS SM1-CF Remote Element Surveillance Microphone is a high-performance, omni-directional microphone that is designed for covert applications. It is composed of a lapel sized microphone and a low noise MOSFET pre-amplifier. Its jumper selects the level of gain, it could be high or low to deliver full output for the amplifier. This microphone can be used with DVRs, I/P cameras, CCTV monitors, both one and two-way remote monitoring equipment and accessories.

With its three positions Euro-style connector, it lets you easily and quickly connect the device to DVRs or any other remote monitoring equipment. The RFI filtering technique eliminates the electromagnetic and radio frequency interference that can deplete the sound and video quality. The selectable on/off treble boost circuitry can be switched on/off to improve the time-lapse recordings, and can accentuate the high frequencies of the pre-amplifier. It also has a limiter circuit that lowers the gain of the microphone's pre-amplifier. This ETS SM1-CF Remote Element Surveillance Microphone can be powered via 12V DC or 24V DC power supply.
