Technical Surveillance Countermeasures
$400.00 per *standard room, $1200.00 minimum fee.
Will detect over 90% of eavesdropping attacks.
Our level 1 survey includes:
Radio spectrum analysis.
We detect, examine, and interpret electromagnetic emissions from VLF into the millimeter-wave frequency range.
Detection of concealed cameras.
We use a proprietary laser-based system to detect the presence of concealed video cameras.
Telephone system analysis.
We perform a meticulous technical inspection and analysis of the telephone system.
We employ a sophisticated thermal imaging system to analyze walls, ceilings, flooring, furniture, and other objects,
for heat signatures which would be characteristic of an active electronic circuit.
$575.00 per *standard room, $1725.00 minimum fee.
Will detect over 97% of eavesdropping attacks.
Our level 2 survey includes all the procedures in level 1 PLUS:
Technical examination for inactive eavesdropping devices and planted tape recorders.
We use a non-linear junction detector to thoroughly examine walls, ceilings, flooring, furniture, and other objects
which should not contain electronic components. We also use a magnetometer to examine objects which should not
contain metal, for metallic shielding, components, or conductors.
$950.00 per *standard room, $2850.00 minimum fee.
National Security Level The most thorough survey available to private industry. Will detect
virtually ALL eavesdropping attacks.
Our level 3 survey includes all the procedures in levels 1 and 2 PLUS:
We use several proprietary instruments, including a sophisticated FFT analyzer, to conduct a thorough analysis of
telephone, electrical, and unidentified wiring for anomalous conditions with regard to capacitive reactance,
inductive reactance, impedance, resistive imbalance, voltage, current flow, audio signals, digital signals, carrier
current transmissions, and multiplexed emissions.
Time-domain reflectometry analysis.
We use a time-domain reflectometer to analyze metallic telecommunications wiring for conditions which would be
caused by a series tap, parallel tap, bridge tap, splice, or split and resplit of the wiring.
We conduct a thorough, methodical, physical search and inspection. This exhaustive search includes all crawl
spaces, drop ceilings, floor coverings, furniture, fixtures, appliances, office equipment, books, and art objects. For
this search we employ a portable real-time x-ray to thoroughly examine objects which are sealed, or might be
damaged by physical inspection; highly-sensitive thermographic imaging to detect the faint heat signatures of
operating electronic circuits; high-intensity ultra-violet illumination to detect variations in painted surfaces, fresh
putty, hidden wiring, or other modifications not usually visible under normal light; and a fiber-optic endoscope to
visually examine the interior of suspect objects. Custom tamper-evident seals are placed on inspected items. Office
and exterior door locks are examined for evidence of picking.
Acoustic transmission analysis.
We use several proprietary instruments to thoroughly evaluate ducting, common spaces, and adjoining areas for
acoustic transmission from 300 hertz to 4000 hertz.
* A "standard" room approximates the size of an average office, 375 square feet or less, and includes one telephone
