This morning after leaving my house, I see 2 guys wearing FDNY shirts and holding clip boards knocking on my door through my front door camera. The guys turned around since nobody answered, walked into my drive way where my other cameras picked them up looking around the driveway for 2-3 minutes. Then they open my backyard gate to go into my yard, look around some more and also knocked on the back door and window to my bedroom and then they leave in some truck parked down a house or two. Anyone else find this strange?? The knocking on the front door ok, but opening the gate to the yard and looking around and knocking on the back door and windows?? 🤨
