Stick up wired cam set up issues

Hi, have a new wired stick up cam. Was working really well until the power went off and has not come back online. Have tried the below - restarting the modem/router - pushing the Orange button - tired a different Poe injector box - removing and trying to re add the unit - full hard reset holding the set up button down for 10+ seconds - different network cables All that happens is that the unit comes on and the blue light remains constant and does not flash or change at all. Anyone have any ideas???
