Final answer:
False. A stand-alone automated access control system can constitute an ESS as it performs the task of controlling access to a physical space.
Step-by-step explanation:
False. An ESS (Electronic Security System) typically consists of multiple subsystems that work together to provide security measures. A stand-alone automated access control system would indeed constitute an ESS as it performs the task of controlling access to a physical space. For example, it may include components such as electronic locks, card readers, and a management software system.
