Covert listening devices

This part of the website is dedicated to small devices that are used to covertly record or intercept a conversation. Such devices are commonly known as bugs and are usually hidden inside the room where a conversation takes place, but may also be hidden inside a wall or work through it.

According to Wikipedia, a bug is a covert listening device [1]. Although many bugs have a built-in transmitter (radio bug), this is by no means mandatory. They can also be wire-based (wire bugs) or connected to existing devices (wire tap bugs). Some bugs are in fact recording devices that are collected after the conversation has taken place. Some modern bugs have a built-in video camera and a TV-transmitter, allowing the conversation to be viewed in a nearby room as well. Some devices are available from commercial shops and websites, such as The Spy Shop and eBay, whilst others are made especially for government agencies and are not available to the general public.

The following bugs are currently covered on this website:

Help us expand this section
This section of the website is by no means finished or complete. We are still looking for additional bugs to expand our collection and show them on the website. We are particularly interested in bugs that were used by the Stasi, the secret police of the former DDR (East Germany). If you have any bugs or related devices that are not shown here, please contact us.

Four different versions. From front to rear: the original Mactron, the Beacon, the Mark II and a prototype of the Mark III
