I hate to add a me too to this, but I am going through the same hell.
Already emailed the ever helpful Aver Surveillance site which came back with Admin 111111.
I mean seriously, my cat could give me a better response.
I bounced that back to them two days ago seeking PIN generation for the Admin@0000 login and have received no help.
--Thanks for any help possible
Fimware version is 3.04.08.00.07
Tried all same combos as above and battery etc.
