NetSurveyor is a Wi-Fi network discovery tool used for detecting and analyzing nearby wireless access points. It provides detailed information in real-time, including signal strength (RSSI), MAC address, SSID, and security settings. Its key feature is the ability to display this data through various diagnostic views and charts, such as time-courses of signal strength and channel usage heatmaps. This directly aligns with the investigator's need to gather and visualize real-time data about local wireless networks for a security audit.
