Just picked up a 32 channel Acusense NVR on eBay for a steal (I know, Blue Iris is King but I want two way audio). I am worried that if they know the verification or QR code they can search for the device once it goes online. Does factory resetting it make a new code? I wouldn't think so because the code is also on a sticker on the unit. I have one camera in my room (to protect against false **** accusations) and DEFINITELY don't want anyone else but my eyes seeing that! Rofl!
