Importance of an Effective Sweep

In order to carry out an effective and reliable sweep, tens of thousands needs to be invested into the necessary equipment. The image on the left shows a transmission from a hidden bug on one of our spectrum analysers. We also employ non linear junction detectors, specialist near field and far field GSM detectors and locators, analysing software, and wideband high sensitivity signal detectors.

There is little point in paying for a counter surveillance or debugging sweep if the company that carries out the service does not have the required equipment and expertise to do the work correctly. A poor or incorrectly executed sweep could result in leaving dangerous and active bugs within your company or home that were not found.

The complex and advanced bugs planted in today’s environments have many built in defence systems that are designed to prevent detection.

Many of these advanced bugs are relatively cheap (costing £ 300.00 or less) and can easily be purchased on the internet by anyone.

Due to the built in defence systems employed by many commercially available devices, it is necessary to use equipment capable of penetrating through the defences, and cheap "bug detectors" used by many Private Investigation agencies or non-dedicated companies are generally not capable of finding or locating many common bugs in a real environment.

A dedicated and effective TSCM counter surveillance bug sweeping company will have invested tens or even hundreds of thousands of pounds in equipment designed to effectively detect and locate the basic and also the more advanced devices.
