Batteries could last a year in a house with adults or 6-8 weeks if you’ve got kids playing in the backyard and forget to disable the motion detection. Quality is good, does not work without internet. You can toggle notifications from the app. We had a high school kid drive through our backyard one afternoon and we got a notification instantly, within 30 mins we not only figured out who it was, he was notified we had him on camera (he didn’t tear up the yard he was playing cat and mouse with other kids/cars) and he apologized.
