I've had mine for a month or so.
I tried to set it up properly, but kept getting hundred of email alerts, with a useless link (was hoping to see a photo of the so-called perpetrator...)
I guess the email is telling me: Hey stupid have a look at the live feed now, hopefully someone is still there..
Even with Sound detection OFF, it sends a message every few minutes, I tried adjusting the area monitored... to no avail..
So I gave up... it's really only good to watch a live feed it seems.
I have hope a firmware or software update will provide a permanent fix. Call me the optimist.
