A:AnswerNo - it doesn't. You can enable the alarm via Alexa, but you can't use the Show to see the video at this time (given the integration it could be a future enhancement).
A:AnswerYou can adjust the sensitivity on the camera. We have not had to adjust ours. I have gotten a few notifications for garbage trucks and larger vehicles. I live across the street from a school and there are a lot of vehicles. I do park my vehicle in my driveway so that may cut down on some of the notifications. I love my camera. It has really helped me feel more comfortable about what is happening outside my house.
