These units operate with a very sensitive transducer placed on the wall to detect sound through the wall.

The surveillance operator now has the option to monitor long distance through the integral transmitter of the ELW as well as on site through headphones. The ELW(en) provides protection against discovery by encrypting the signal before transmission. ( only on request )
