The Accessories

These four optional devices are designed to facilitate and expedite surveillance sweeps.

The SS Series

At ISA, we offer two sound sources codenamed SS-1 and SS-2. The sound sources create an easily recognizable “chirp” inside the area that is being analyzed for eavesdropping devices; even when other noise is present. The SS-1 has a AC/DC adapter while the SS-2 contains a battery and recharger for use in powerless areas.

The PNG-1

The PNG-1 is a pink noise generator that provides a gentle sound similar to falling rain to mask the sound of conversation pick-up from microphones. Coverage is dependent on room size but four units cover approximately 200 sq feet. It operates on an internal 9 volt battery or an optional plug in pack.

The ELI-1

This battery powered telephone extension eavesdrop indicator provides positive indication when an extension phone is lifted off hook. It will also indicate the presence of less sophisticated eavesdropping devices such as tape recorders and transmitters if they draw operating power from the telephone line.

The PLD-1

The PLD-1 is a current carrier transmitter detector and will determine instantly if a current transmitter is present on the standard AC power lines.
