Aspects of the present invention include a system and method for detecting one or more objects detected behind an opaque surface, comprising collecting, by a plurality of sensors of a scanner, sensor data of the one or more objects behind an opaque surface; identifying, by one or more processors of the scanner, characteristics of signal strengths detected by a pair of capacitive sensors using the sensor data, including concurrent behaviors of a first capacitive sensor and a second capacitive sensor in the pair of capacitive sensors; analyzing, by the one or more processors, the characteristics of signal strengths detected to determine different regions of the one or more objects behind the opaque surface; and informing a user, by the one or more processors via a user interface of the scanner, of the different regions of the one or more objects behind the opaque surface.
