What is a 'verification' signal in alarm systems?

A verification signal in alarm systems serves as a confirmation that the triggering event of the alarm may indeed be a legitimate occurrence. This type of signal is part of an effort to reduce false alarms, which are a common issue in security systems. When an alarm system sends out a verification signal, it indicates that the system has validated the alarm condition through various means, such as corroborating information from sensors or other security measures that suggest an actual intrusion or emergency may be happening.

This verification process is important as it helps distinguish between false alarms—which could occur due to benign errors or malfunctions—and genuine threats that require immediate attention. By clearly identifying potential legitimate events, verification signals assist in prioritizing responses from security personnel and emergency services, enhancing the effectiveness of overall security strategies.
