We place great importance on preparation for an observation task, as this best leads to obtaining the required end-result.
Surveillance can refer to surveillance cameras, aerial surveillance, profiling, social network analysis, computer surveillance, and, of course, human operatives that carry out surveillance.
Computer forensics refers to both data recovery and the investigation of criminal activity. Data recovery involves the recovery of data that was lost to an individual or business whereas the investigation of criminal activity is much more complex in that it involves laws, legal systems, and the finding of evidence that can be produced in court
“Absolute and focused observation is necessity for any successful surveillance.”
