What is the difference between reconnaissance and surveillance?
"I think reconnaissance deals with gathering information about targets whereas surveillance deals more with movement and coordination of units. "
Reconnaissance looks for new (or more) detail about subject targets whereas surveillance looks for indications of confirmation or change of existing information; hence, its frequent relationship to "movement". NATO defines the two (as taken from the NATO reference: APP-6):
Surveillance. The systematic observation of aerospace, surface and subsurface areas, places, persons, or things, by visual, aural, electronic, photographic, or other means.
Reconnaissance. A mission undertaken to obtain, by visual observation or other detection methods, information about the activities and resources of an enemy or potential enemy, or to secure data concerning the meteorological, hydrographic, or geographic characteristics of a particular area. .
The major difference between passive surveillance and active surveillance is that passive surveillance relies on pre-existing data or data that is usually reported by public health officers or health care providers to health departments while active surveillance involves proactively collecting data from patients or participants from the general population.

Overt surveillance is when the subject has been informed of the nature and scope of the surveillance being conducted and/or the surveillance devices are clearly labeled and displayed.

Research is usually very purpose-driven and is set to answer a question by doing something hands-on, such as an experiment or a study. I consider surveillance to only be watching. You may still be answering a question, but you yourself would not do any kind of experimenting as a means to answer that question.
A casework style of supervision helps the offender with problems, providing counseling, and ensuring that the offender completes supervision. On the other hand, A surveillance style of supervision is when the offender is being monitored and enforce the offender to comply with the rules and supervision. If they detect a violation then they will revoke there probation and put them back into custody.
