It's the Ring doorbell and app.  I have one on my house, and it records any movement at my door. And when someone rings the doorbell, it sends a notification to my phone and I can talk to and see whoever is there from wherever I am. It's really cool!   I think I need to set up a bait bowl and wait for Fatty McGoo to come by and steal it all, to later post online and shame the fuck out of them.
