What is the main difference between audible and silent alarms?

The distinction between audible and silent alarms primarily hinges on their operational purpose and functionality. Audible alarms are designed to emit sound, serving as a deterrent by alerting not just the occupants of a space but also individuals outside the premises to potential intrusions or emergencies. This loud signal can trigger a response from nearby individuals or security personnel.

In contrast, silent alarms operate quietly, usually notifying only the authorities or a monitoring service without alerting the intruder or other individuals in the vicinity. This discretion can be crucial in situations where making noise could compromise safety, such as during a robbery or when dealing with intruders.

Understanding this fundamental difference underlines the strategic application of each type of alarm in security systems, emphasizing how they are deployed based on varying circumstances and security needs.
