Abstract: Advertising devices, systems, and methods of monitoring an effectiveness of an advertising campaign are disclosed. An advertising device includes one or more imaging devices, a processing device, and a storage medium. The storage medium includes programming instructions that, when executed, cause the processing device to receive image data from the one or more imaging devices. The image data includes information regarding one or more individuals located in a vicinity of an advertising channel. The storage medium further includes programming instructions that, when executed, cause the processing device to determine a total number of the individuals to generate reach data, determine a subset of the total number of individuals that corresponds to a number of engaged individuals that observe the advertising channel, determine a duration of engagement for each individual to generate engagement data, and transmit the reach data and the engagement data to a remote computing device.
