What factor can lead to false alarms in alarm systems?

Improperly set sensitivity levels can lead to false alarms in alarm systems because these settings determine how responsive the system is to potential security threats. If the sensitivity is set too high, the system may register benign activities—such as pets moving around, small animals, or even environmental changes—as threats, resulting in frequent false alarms. Conversely, if the sensitivity is too low, actual security incidents may go undetected. Adjusting the sensitivity levels appropriately is crucial for striking a balance between security and minimizing unnecessary alerts, thereby ensuring that the system only triggers alarms in response to genuine threats.
