The paper deals with digital surveillance in the postmodern world. We define a new term 'Surveillance of Things' in the context of the study of the surveillance, and try to determine, whether and how the surveillance of people is connected with surveillance of things. We pay particular attention to the Internet of things and analyze in detail the principles of Sigfox network. We work on the presumption that information about people obtained through surveillance of things are interpreted incorrectly and can have a direct impact on groups of people and also individuals.

The article examines wages in the field of information and communication technologies (ICT). Based on the so-called ISPV data (adjusted for inflation), CZSO and Eurostat data, several analyses were performed. The main conclusions are: (1) The number of ICT workers grew faster, their share in total employment increased from 2.2% to 3.9%. (2) From 2008 to 2013, the overall trend in wages is declining and they have been growing significantly since 2014 (influenced by both economic growth and falling inflation). (3) Wages of ICT specialists (CZ ISCO 25) grew considerably faster than those of ICT technicians (CZ ISCO 35). 4) Wages for the entire ICT and for the CZ-ISCO 25 category grew faster than GDP. (5) The gender pay gap in the Czech Republic is among the highest among the countries surveyed, although in 2019 it decreased compared to 2008. (6) Within the Czech Republic, the differences between the salaries of men and women in ICT are smaller than for the entire economy.
