Ok I saw again the entire scene from timeline.. The woman when she entered for the first time was calm and didn't care about the cams, she starts to reorder and clean but she wasn't surprise to see the cams. After a few minutes she called maybe her husband (?) telling him to come to remove the cams (maybe she wasn't capable with technologic stuff).. When the man came he didn't know if he could remove the cams, so they started to argue.. Mainly about the mess, then about the cams too but it seems they already knew about the cams... So she called someone maybe James or someone else, maybe they were expecting to find the apartment in order and without cams...
