CM-2 Covert Microphone

The Covert Microphone provides an ultra high sensitivity microphone that can be used in place of the standard system speaker to provide listen only functions or can be combined with the RS-1 system speaker and the 4-X box to provide multiple listening points. The electronics and the microphone are protected in the metal box. Operating power for the microphone preamplifier is obtained from the TCU-02 so there are no batteries to worry about or replace. The flexible metallic tube can be bent for insertion under doors, through cracks in window frames or through holes bored into the premise.
