Counter Intelligence services

First Response Investigations carry out bug sweeping and detection in most areas and environments where we use the latest high level electronic counter surveillance and debugging equipment to locate all types of electronic listening devices / bugs, telephone taps, hidden video, radio and microwave devices.

Whilst bug sweeping and detection (debugging) we will be conducting a two part search; looking for Hardwire, Radio Frequency, 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 using our bug locating equipment. We will search all possible areas including telephones and phone lines both inside and outside the property.

In addition to the initial search, we recommend further regular debugging searches to maintain your security and peace of mind. We have the bug sweeping and detection equipment and experience to carry out complete searches in the following locations.

Home
Office
Factory
Vehicle (car and van)
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 three 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. Our FM / AM / Microwave scanner device can then intercept these signals.

With today's technology local spy stores and the internet are selling RF transmitters for under 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 a new product. 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 helps in locating RF transmitters however the main part of the search is by using an RF detector / locator.

Our system searches into the low Hz to a very high GHz range, if a signal is picked up we are notified through various means (i.e. audio, vibration, meters...) and can track/pin point where the transmitter is located, (in between walls, above ceiling tiles, under furniture).

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 removal of all electrical outlets, air vents, ceiling tiles, smoke detector covers, light switch covers etc for inspection.
