Counter surveillance bug sweeps

Crown Intelligence's Private Investigators carry out Counter Surveillance bug sweeps and detection in most areas and environments with a 24 hours emergency service. We use some of the industries most advanced electronic counter surveillance and debugging equipment to locate all types of electronic listening devices / bugs, telephone taps, hidden video, radio and microwave devices.

In a counter surveillance sweep - TSCM, our special division of Private Investigators will be conducting a two part search; looking for Hardwire, Radio Frequency, GSM and laser / Infrared bugs. The two part search will consist firstly of a physical search, where we will inspect electronic equipment and suspect areas for known devices and then for the second part we will carry out an electronic RF spectrum and audio search including a GSM search using our counter surveillance equipment. Our Private Investigators will search all possible areas including telephones and phone lines both inside and outside the property.

Bugs can be extremly small, and can be placed into many items such as a pen, a mouse, or a plug.

 

In addition to the initial counter surveillance search, we recommend further regular debugging searches to maintain your security and peace of mind. This is due to the ease with which individuals can plant bugging devices at some time after our search is completed.

Our Private Investigators have the bug sweeping and detection equipment and experience to carry out complete counter surveillance sweeps in the following locations.

Home
Office
Factory
Vehicle (car and van)
Micro devices fitted in clothing
Electronic equipment such as phones, radios, televisions, clocks, lamps etc.

In order to explain the risks that you may encounter from being bugged we have detailed the four main types below.

Hardwire, (Telephone & Telephone line search).
A Hardwire bug or transmitter is a listening device that is attached to your phone or phone line. It's generally powered by the line or the phone itself, These are often hard to detect as they generally only transmit when a call is in operation. A hardwire transmitter can be placed on the phone, line, or central telephone system. The transmitter can even be placed on your line outside of the building, or down the street at the junction box.

Radio Frequency (RF), (Spectrum & audio search).
RF transmitters send wireless signals through the air. A FM / AM / Microwave counter surveillance scanner device can then intercept these signals.

With today's technology, local spy stores and the internet are selling RF transmitters for less than a hundred pounds. This is making it increasingly easy for "interested parties" to place a device in a room and listen to meetings, important company decisions, or discussions about new products or services. A common place is in the personnel department where details of other employees can be learnt.

These bugs can be located within electrical outlets, under furniture, inside an ornament, clock, or even in a book. A physical search by a Private Investigator will assist the sweep, but the major part is completed by electronic scanning equipment.

GSM bugs

Laser/Infrared bugs.
These types of listening devices operate through a window or similar opening. An operative could easily setup the equipment via tripod connected to a transmitter and intercept your communication from miles away. A laser or infrared beam is shot into the room from any distance of up to many miles away. The audio in that room is picked up by the laser beam and transferred into data that is then sent over the light or infrared beam back to the sender. The sender normally has a recorder connected to the equipment and can record the conversation.

Physical search.
The inspection of mains sockets, suspended tiles, some equipment and suspicious or new fittings.
