What classification is given to a privately owned and monitored alarm system?

A privately owned and monitored alarm system is classified as a proprietary system. This classification indicates that the monitoring and maintenance of the alarm system are handled by the owner or a designated party rather than through a public or municipal oversight. Proprietary systems are tailored to the specific needs of the owner and often involve unique configurations and monitoring solutions that are distinct to their properties. Combining private ownership with monitoring creates a controlled and customized approach to security, ensuring that the system meets the individual requirements of the property owners without the need for public resources or services.
