The STW3 is a two-way single zone audio surveillance system which is designed and manufactured by ETS which can be used for independent live audio monitoring or to be used with tape recorders with record/playback functions.

The STW3 consists of an optional call switch button and can come with a STW1-S surface mount, or a RM-4 rack mount.

To connect the Microphone from the ETS STW3 Single Zone 2 way Audio Surveillance Kit, run a 22 gauge, 2 conductor shielded cable (1,000 feet maximum length) between the STW1 and the STW2 base station. Keep the cable away from AC power sources, light fixtures and electrical equipment.
