The Picture Frame Bug

If you want a very deceptive listening device, the picture frame is the one to go for. This device has a nice little microphone sitting at the back of it and you can listen to all that is happening in the room using this device by just making a phone call.
How does a phone call turn the listening features on? A simple phone call will activate the microphone and you can listen in on every bit of the conversation. The picture frame will make no one to think that they have a bug on them.
Now who would find such a device useful? Obviously spies and people very insecure about what’s happening behind their backs in their won homes, even parents who worry a lot about their teenagers!!!
