The aim of ADMOS aim is to develop a compact monitoring device that can be installed additionally on public media interfaces, which is able to provide information about the displayed advertisement, and to give feedback about the obtained contact number and the pattern attributes. The ADMOS system will consist of two cameras (one facing the board and the other facing the public) integrated together with a mobile communication unit so the collected information can be monitored through the internet. The objective is to gain detailed information about the composition of the sample, what means to define the age, gender of the people walking by and whether the person has noticed the advertisement. The system will be controlled through a software that will be able to analyse the collected data and present the results for the system owner (according to a day/week/month/year campaign). The system will enable the user to check the media device 0-24 h and send automatic alerts in case of a failure. As a result ADMOS will offer the user (both advertiser and outdoor media owner) a tool that can give an objective and accurate analysis of the audience for any advertising board (digital or paper based). In addition the system will be able to monitor the board as well assuring the owner and the advertiser that the right images are displayed. The benefits of this technology will mean that more effective and directed advertising can be achieved (reducing unnecessary and ineffective marketing).
