Key Differences

Surveil is primarily associated with continuous observation or monitoring, typically for security or intelligence purposes. On the other hand, a survey is a method used to gather information, opinions, or data from a group of people through questionnaires or statistical studies.
The term surveil is often used in contexts related to law enforcement or espionage where discreetness and ongoing vigilance are paramount. Whereas, surveys are commonly employed in research, marketing, and social sciences to assess trends, preferences, or behaviors among a specific population.
Surveil typically implies a more secretive or covert action, focusing on the surveillance of specific targets or areas. In contrast, conducting a survey is a more open and interactive process, involving engagement with participants to collect data.
Surveillance activities are usually not disclosed to the public or to those being monitored, emphasizing secrecy and confidentiality. On the other hand, surveys often require informed consent from participants, especially in academic or market research, reflecting a level of transparency and ethical consideration.
The tools and technologies used in surveillance include cameras, wiretaps, and sophisticated software for data analysis. Conversely, surveys primarily utilize questionnaires, interviews, and statistical software to analyze the collected data and draw conclusions.
