If you think you're being monitored - consider this:-

Most telephone instruments can be easily and quickly modified to function as a room listening device and still operate normally on the phone line.

A tiny microphone can be attached to the cable of an intercom, burglar alarm, doorbell, electrical mains circuit or virtually anything using wire to turn it into an effective listening device.

A audio bug can look and behave like a normally functioning everyday object. i.e. a pen that writes, an electrical plug that operates normally or perhaps a light fitting that does more than simply illuminate your room.

It only takes a few minutes to install a bug into a motor vehicle. It can operate indefinitely and be listened to over any distance - even when the vehicle is travelling at speed.

Many listening devices are operated by remote control and some use highly refined encryption techniques.

Cameras are becoming smaller every day. They are extremely sophisticated, cheap to purchase and can be hidden almost anywhere.

Sophisticated surveillance equipment is very affordable and almost anybody can use it.

If the consequences of being overheard or observed are unacceptable, either avoid those situations that could compromise your privacy or protect yourself by using some decent and reliable quality counter-surveillance product.
