Common Pitfalls
Translation Traps (for Russian speakers)

- Прямой перевод 'надзор' может быть слишком узким; 'надзор' часто предполагает проверку качества (factory oversight), тогда как 'surveillance' – скрытое наблюдение.
- Не путать с 'observation' (нейтральное наблюдение). 'Surveillance' всегда подразумевает цель контроля или сбора информации.
Common Mistakes
- Using it as a countable noun (e.g., 'a surveillance' is incorrect).
- Misspelling: 'surveilance' (missing one 'l'), 'survelliance'.
- Incorrect preposition: 'on surveillance' instead of 'under surveillance'.

FAQ
Frequently Asked Questions
It is denotatively neutral but often carries negative connotations related to loss of privacy, state control, and intrusion, especially in contemporary discourse.
No, 'surveillance' is typically an uncountable noun. You cannot say 'a surveillance'. Instead, use phrases like 'a surveillance operation', 'a surveillance system', or 'a period of surveillance'.
'Observation' is general and neutral (scientific observation). 'Surveillance' implies a specific purpose—control, security, or gathering information—and is often systematic, sustained, and can be covert.
Yes, but it is less common and more formal/technical than the noun. It is a back-formation from 'surveillance'. 'Monitor' or 'watch' are more frequent in everyday language.
