I'm honestly really disappointed in it because 99% of the alerts I get from this camera are false alarms. The most frequent offender is light from passing vehicles. It is worse when it has rained and the reflection of headlights can be seen in the "zone" I have set up to send me alerts. You would think Google would be able to drop false alarms down to nothing for the common things like everyday street traffic, but apparently not.
They also have a weird rule where you can only get 1 notification within a 30 minute window. So if I take my garbage outside and the camera sees me, it will send an alert. If an axe murderer comes onto the property 20 minutes after that, the camera won't alert me.
