I have had to shut down the sound detection on my V2 because the phone ringing would set it off and send me a notification. Then, if a message was left, the beep of my answering machine every 2-3 minutes would set it off. Is this normal?
Well, yes, it’s normal. After all, it detected sound and acted accordingly. There is no setting for ignoring certain types of sound. You can try to decrease the sound sensitivity in the settings to the point where it ignores the phone and beep but still catches other sounds you want. But if the phone ringer is loud or close to the camera, that might not work.
