Surveillance typically involves monitoring individuals, groups, or activities for the purpose of gathering information, often without their knowledge or consent. Observation, on the other hand, refers to the act of simply watching or noticing something, without the connotation of monitoring or gathering data covertly.
An observation is a statement of something that has been directly witnessed or perceived. An explanation, on the other hand, is a statement that clarifies why or how something happened, providing reasoning or insight into the observation. Observations are what we see or experience, while explanations seek to make sense of those observations.
A short range observation refers to gathering data or information from a close distance, typically within a limited range or proximity to the subject being observed. This type of observation is often used in fields such as wildlife research, surveillance, or security monitoring where detailed and immediate data is needed.
Visible observation refers to the act of physically seeing or watching something with the naked eye. It involves directly looking at an object or phenomenon to gather information or draw conclusions based on what is observable through sight. This type of observation is typically used in scientific research, surveillance, or monitoring activities.
