What does a combined technology sensor in an intrusion system aim to achieve?

A combined technology sensor in an intrusion detection system aims to minimize false alarms caused by environmental factors. These sensors integrate multiple detection technologies, such as motion detection, video analysis, and sometimes audio sensing, to create a more reliable system. By utilizing diverse methods of detection, the sensor is better equipped to differentiate between actual intrusions and benign events, such as animals moving through the monitored area or changes in lighting. This capability is critical for enhancing the accuracy of the alarms generated by the system and ensuring that responses are reserved for true security threats.

In contrast, options related to increasing network bandwidth, improving wireless communication, or enhancing visual detection do not directly pertain to the primary function of combined technology sensors. While they could be relevant in broader contexts of system performance or individual technologies, they do not specifically capture the advantage of reducing false alarms by leveraging multiple detection methodologies.
