I do have one of those ring doorbell things and we also have a couple of cameras elsewhere on the outside of the house for security purposes (long story).
We do have a couple of cameras in the house in order to keep an eye on our cat that is an indoor cat only.
I have a doorbell camera, but that's about it. Mostly it just goes off when neighbors come and go or if someone's coming in/out of the house, but it's been nice to have because we can see who's at the door if we're not expecting someone or I can check on packages we've received while I'm not at home to make sure there's no issues.
We have two outdoor camera font, back and then an indoor for the basement. it is only setup to operate in the evening or when we are gone, otherwise the privacy shutter is closed.
I don't currently have a camera setup due to I am renting this house. But I think I may invest in one in the near future. I do like the idea of having eyes on the house when I am not around. I need to upgrade my internet before I do that though.
