Systems (100) and methods (110) for operating a physical security surveillance system. The methods involve: detecting the constant unencrypted radio transmissions of mobile phones in order to capture in a cloud-based archive the identities, geographical trails, speeds and motions of most people nearby deployed units. Once recorded by a locally deployed sensor (104), the aggregated data (102) from the recorded mobile phones (106) is pooled in a globally inclusive database, synthesized, processed and filtered. On a paid-subscription basis, the data is accessible in a searchable archive that includes dozens of search parameters and filters. Users may visualize geographical trails of mobile phones on a multi-featured map, a geographically corresponding input of Google Street View, or a geographically corresponding input of video surveillance. Users may receive text message alerts when designated blacklisted individuals trespass in designated surveillance zones.
