Technical Surveillance Counter Measures (TSCM) is our specialty. We eliminate telephone line bugs and wiretaps (using wiretap detection sweeps), computer data line taps and bugs (telecommunications security line sweeps), and bug sweep your conference rooms (using electronic room bug sweeping and electronic detection). Our superior equipment can detect electronic espionage and our unparalleled experience and knowledge can identify and locate those bugging devices. Get more information on bugs, wiretaps, and phone taps. Help to protect yourself and your company from invasions and thefts due to surveillance wiretaps and bugs. Many corporate trade secrets are compromised and executives have been kidnapped for ransom due to inside information gained by wiretaps and bugs. Recently, cases of computer theft and alteration of computer records have been perpetrated by criminals who gained access to telephone data lines using electronic bugs. TSCM - Technical Surveillance Countermeasures

As expert design and installation professionals, we are familiar with every type of hidden surveillance camera or phone tap and bugging system available, and we know what to look for when retained to conduct technical surveillance countermeasures (TSCM), or video and audio ‘bug sweeps’. We are, therefore, in a position to advise you that your concerns are potentially valid if you have noticed any of the following indications.

Technical Indications
During telephone conversations, there are audible popping, scratching, or unusual noises present which indicate the presence of a wire, or phone tap. Static or volume changes likewise can be indications of capacity discharge caused by the amateur installation of a phone tap.
The telephone handset emits unusual sounds while still on the hook. This can be the result of a ‘switch hook bypass’, which allows the telephone to become a microphone. This is not actually a phone tap -- it is a bug which permits eavesdropping to within 25 or 30 feet of the telephone, and is easily found during the sweep if the right equipment is used.

The telephone rings but no one is there. However, there is a brief beeping or high-pitched squealing. This can be an indication of an ‘infinity transmitter’ or ‘harmonica bug’, which is also easily detected during a sweep. With the television turned on but the volume turned off, there is a slight herringbone pattern visible on the screen whenever conversation takes place in the room. This could be a strong indication that there is an eavesdropping transmitter hidden in that room, which is, again, easily found during a properly-conducted detection sweep.
