It may not be a supported feature but I believe that they are triggered by sound. So my question is, how do I prevent my cameras from being triggered by sound? Mine are consistently triggered by vehicles, like garbage trucks, that drive by. I have two cameras on the front of my house, one at the front door and one at the garage, neither has a view of the street. Without fail a truck drives by, triggers the front door camera, then the garage camera. I get notification after notification after notification… with videos that show no movement, only sound. Any ideas??
