CERN's Future Circular Collider Study involves two accelerator stages in a common 91-km tunnel. In the first stage, FCC-ee, electron-positron collisions will be studied at very high luminosities in the centre-of-mass range between 90 and 365 GeV, allowing measurement of the the Z, W, and Higgs bosons and the top quark with very high precisions. In the second stage, FCC-hh, proton-proton collisions at 100 TeV will allow searches for BSM physics at the energy frontier as well as very precise measurement of Higgs couplings. FCC-ee is characterised by very high event rates - over few years, 5 x 10^12 Z bosons will be produced - and hence very low statistical uncertainties. This poses strict requirements on the quality of detectors in order to minimise as far as possible also the systematics uncertainties. The FCC-ee physics landscape is still under exploration and not all detector requirements are still completely developed. In this talk, I will discuss the currently understood detector requirements and the technologies suggested for dealing with these by the Detector Concepts currently taking form.
