Doorbell chimer & Camera view

Whenever I attach the video doorbell to the entrance, the chimer bells begin to vibrate uncontrollably, and then rings when no one is pressing the ring button.  When I remove the doorbell, it stops, when I connect it again, the chimer begins to vibrate again, which makes it ring.

I don't know what could be the remedy.

Also, my doorbell is in the corner of my door, so half of the camera is taking in my brick wall instead of the rest of my yard.  Is there some extension Simplisafe has that can extend my doorbell and make it stand out to see more of the view?

Thanks.
