This room transmitter uses the CR2032 battery and has been designed for fixed room use and body worn applications.
It is a professional surveillance transmitter for the most demanding situations.
When building hidden transmitters into briefcases, desktop lighters, ashtrays, pocket calculator, and other everyday objects, no one would suspect that those items possess disguised transmitters. Because room transmitters come as hidden transmitters and disguised transmitters, they are able to capture conversations without being noticed.
A room transmitter works the same way that room bugs and surveillance transmitters operate. Each is able to hear conversations in a room, amplify the sound from those conversations, and broadcast them over the air to a surveillance receiver. Room transmitters can send conversations to a receiver with a surveillance recorder (STV-05 receiver). In that way, the room transmitter is also able to save the conversation for future review.
