After the first day of receiving 6 notifications in under an hour, we had to turn off one of the advertised features. Luckily, a few weeks later they added the ability to adjust the sensitivity and I just so happened to have an iPhone in a drawer, and I was able to use the iOS app to put it on low. Now we don't get any notifications from the motion sensor. Now that I think about it, I am actually concerned if it is working at all on low. We have packages delivered and such and I haven't had any notifications since making the adjustment. I see in other reviews apparently changing to low makes it as useless as high. Where with high you get constant notifications and low it is nearly impossible to trip the motion sensor. I haven't done further testing myself, but that seems to be holding true here given the activity I know has been in front of it recently. The biggest issue I have had with this unit, which literally took 2 months of exchanges with their support before I figured out a solution, was getting the video, yes the head line feature, to work. On demand and button pushes would sometimes take 30 seconds to 2 minutes for the video to start coming through and even then it would be just primary colors or video with static in large areas of the video or a black screen with little dots of light randomly spread out. Completely useless if trying to id a vandal or package thief or to have a conversation with whoever was there because usually they weren't there but I couldn't tell since I couldn't see.
