In practice, the terms ‘security company’ and ‘surveillance company’ are often used interchangeably, but there is a substantive difference between them. Surveillance generally refers to the passive observation and monitoring of a site, such as CCTV surveillance or regular patrols. Security, on the other hand, also encompasses active intervention, access control, incident management and the deployment of certified security guards with the authority to make arrests. AE Security provides fully certified security services in the broadest sense of the word, not just passive surveillance.
