Notovia's tense observation horrors

Most of these nine games from Notovia ask you to stare at quiet rooms on night-watch screens and catch objects that move, disappear, or show up where they should not, then send in a form before time runs out. I'm on Observation Duty 5 gives you six places to check through the night, while I'm on Observation Duty 4 centers on clearing each strange event to stay until morning. For something different, Trader of the Night swaps cameras for company shares, asking you to trade carefully to clear what you owe.
