De Bugging & Sweeping Services:
Electronic Eavesdropping & Video Recording
Modern listening devices (bugs) and covert video recorders are tiny, powerful
and easy to hide. Any conversation or action taking place can then easily
be recorded with surveillance equipment.
We are able to install wiretaps, mobile and landline listening devices as
well as hidden video camera and recording equipment.
All de-bugging, eavesdropping and discreet filming operations are carried
out with the clients full knowledge and in accordance with South African Legislative
requirements, including Act 127 of 1992, the Interception and Monitoring Prohibition
Act.
Eavesdropping operations generally have three principal elements
- Pickup Device: A microphone, video camera or other
device picks up sound or video images and converts them to electrical
impulses. The devices can be installed so that it uses electrical power
already available in the target room, this eliminates the need for periodic
access to the room to replace batteries. Some listening devices can store
information digitally and transmit it to a listening post at a predetermined
time. Tiny microphones may be coupled with miniature amplifiers that filter
out background noise.
- Transmission Link: The electrical impulses created
by the pickup device must somehow be transmitted to a listening post.
This may be done by a radio frequency transmission or by wire. Available
wires might include the active telephone line, unused telephone or electrical
wire, or ungrounded electrical conduits. Transmitters may be linked to
an existing power source or be battery operated. The transmitter may operate
continuously or, in more sophisticated operations, be remotely activated.
- Listening Post: This is a secure area where the signals
can be monitored, recorded, or retransmitted to another area for processing.
The listening post may be as close as the next room or as far as several
blocks. Voice-activated equipment is available to record only when activity
is present. Most recorders can record up to 12 to 24 hours of conversation
between tape changes.
Electronic Sweeping

Our
counter espionage or Debugging service use state of the art electronic detectors
and sweepers, equivalent to those used by National Intelligence. A Technical
Security Countermeasures (TSCM) survey, also known as a "sweep,"
is done by qualified, experienced consultants specializing in the field of
detection. They can detect the presence of technical surveillance devices
and hazards as well as identify technical security weaknesses that could facilitate
a technical penetration of the facility.
To optimize your corporate security we include the following sweeps;
- Detection of wiretaps on Telephone Lines, Private Lines, Fax Lines,
Extension or Incoming Lines and distribution facilities also knows as
PABX or other Internal Call Distribution Facilitators.
- Detection of hidden cameras
- Securing of computer data lines
- De-bugging telephones and mobile cellular phones
- Eavesdropping Detection in Open Office Areas which may include Corporate
Space, Offices and Boardrooms.
- De-bugging of your home and car.
- A physical examination of interior and exterior areas, false ceilings
and heating, air conditioning, plumbing, and ventilation systems for evidence
of eavesdropping.
