What is the purpose of a siren in an intrusion detection system?

The purpose of a siren in an intrusion detection system is to alert an individual that the alarm system has been triggered. Sirens serve as an audible warning signal that draws attention to the event of a security breach or unauthorized access. When the intrusion detection system detects suspicious activity, the siren activates to notify individuals nearby, which can serve to deter the intruder and prompt a response from security personnel. This immediate auditory alert is crucial for effective incident management and aids in protecting the premises.

In the context of intrusion detection systems, capturing video footage and providing communication might involve different components such as cameras and communication devices. Regulating temperature is entirely unrelated to the functions of an intrusion detection system. Thus, the primary role of the siren focuses specifically on alerting individuals to ensure prompt action is taken in response to potential threats.
