You will get notifications and alerts. The camera would also start recording if you have that feature. But you can adjust the settings to low sensitivity which I did. I live on some what a busy street; school buses, garbage trucks and large SUVs still get picked up and I get alerts along with people approaching my door. I believe they’re coming up with an update that will learn what’s actually passing by and who is coming to your door soon. I overall love it, the only downside is with low sensitivity it doesn’t alert you fast enough to those quickly approaching your door but it does start recording right away.
