Monitoring a physical area for unauthorized access by a user of a wireless device includes setting a wireless signal scanning range using at least one wireless scanning device, detecting a wireless signal within the scanning range, determining a status of the wireless device of authorized, unauthorized or unknown, monitoring scan data obtained from the scanning device during the time the wireless signal remains within the scanning range. A scan data pattern based on the monitored scan data is determined and compared to a scan data pattern database containing scan data patterns indicative of suspicious behavior and determining whether the monitored scan data pattern matches a suspicious scan data pattern based on the comparison. The system identifies the wireless device as unauthorized in response to a match with a suspicious scan data pattern and activates a security alert.
