I am sure the motion sensor is good for a backyard where there's little movement, but not for the front of the house where there's constant movement. I set up motion zones to let me know when there's someone in it, and it triggered every time when someone was caught in the camera, disregarding the zone set. I got so many false alerts each day that I had to turn it off.
But honestly, I want more than what it offers that I cannot tap into... for instance... if someone is trying to break-into my house in the middle of the night I need a phone call or a way connect the camera to my alarm system. A simple phone notification won't wake me up.
It would also be useful to review every time the camera saw a person in the middle of the night when it matters most... not during the day when dozens of people walk in front of it.
I also need to be able to distinguish when it detects a person that's far away, like across the street, and someone who's right in-front of the camera, filling most of the frame.
