I wouldn't really call it a mistake. 
It has been recording most of the summer now. 
I caught the assesor measuring the house, and a maintenance guy "watering the lawn" . 
It has not given me any problems.   
As for the internet, not really a big concern of mine.   
I just wish it came with the pir sensors is all, that and the outgoing signal seems to be in quad mode only, which makes the details kind of small.
