Clinical surveillance refers to the monitoring of diseases or public health–related indicators (for example symptoms indicating an act of bioterrorism) by epidemiologists and public health professionals. The word is pronounced /sɚˈveɪəns/ or /sɚˈveɪləns/.
Although the word surveillance in French literally means "watching over", the term is often used for all forms of observation or monitoring, not just visual observation. Nevertheless, the all-seeing "eye in the sky" is still a general icon of surveillance. Surveillance in many modern cities and buildings often uses closed-circuit television cameras. Although surveillance can be a useful tool for law enforcement and security companies, many people have concerns about the loss of privacy.
The word surveillance is commonly used to describe observation from a distance by means of electronic equipment or other technological means. For example:
eavesdropping;
telephone tapping;
directional microphones;
covert listening devices or "bugs";
Minox subminiature cameras;
closed-circuit television;
GPS tracking;
Bait car;
electronic tagging;
CCTV Images;
military reconnaissance;
Reconnaissance aircraft, e.g. Lockheed U-2;
Reconnaissance satellites;
"trusted" computing devices;
Internet and computer surveillance;
However, surveillance also includes simple, relatively no- or low-technology methods such as direct observation, observation with binoculars, postal interception, or similar methods.
Counter surveillance, inverse surveillance, sousveillance
Surveillance is the art of watching over the activities of persons or groups from a position of higher authority. Surveillance may be covert (without their knowledge) or overt (perhaps with frequent reminders such as "we are watching over you"). Surveillance has been an intrinsic part of human history. Sun Tzu's The Art of War, written 2,500 years ago, discusses how spies should be used against a person's enemies. But modern electronic and computer technology have given surveillance a whole new field of operation. Surveillance can be automated using computers, and people leave extensive records that describe their activities.
Counter surveillance is the practice of avoiding surveillance or making surveillance difficult. Before computer networks, counter surveillance involved avoiding agents and communicating secretly. With recent developments — the Internet, increasing prevalence of electronic security systems, and computer databases — counter surveillance has grown in scope and complexity. Now counter surveillance involves everything from knowing how to delete a file on a computer to avoiding becoming the target of direct advertising agencies.
