I just purchased a smart home loaded with Ring and Nest devices installed by the previous owner. I'd like to start by getting the Ring doorbell camera working that is mounted to my front door. I've checked around but am still unsure what model I have. I purchased a screwdriver that was described to work for removing the cover security screw,  but it didn't fit the single screw located on the bottom center of the Ring camera.  Can anyone please tell me what model I have going by this picture? Thank you
