'Inconvenience is kept to a minimum' sounds about right for Aurora, as far as Ned's heard. No doubt those backup procedures would involve robot labor, carried out in some quick and discreet way so that the estate owners barely even noticed anything was the matter. When Ned thinks about that, he feels (though he wouldn't admit it) rather glad that he isn't like them, that he can adjust to a lack of electricity and find the fun in it.

"Do you think we should check?"

Ned knows that tampering with the cameras is in some ways asking for trouble, but they usually weren't replaced for hours. Still, he's hesitant, reaching out in the darkness to set a hand on Daneel's arm.

"What if it... I don't know, what if it's booby trapped and shocks you, or something like that?" He's torn between his desire to know, to let Daneel investigate, and his concern for Daneel's safety (even if Daneel isn't as concerned for it, himself).
