I have a lot of IoT devices in and around my home, including some cameras. I don't trust any of the smart devices, which is why they all have offline/locally controlled operation modes and are segmented off from the rest of the network with their own manufacturer/purpose specific VLANs and firewall rules.
I don't think most people comprehend what their devices are doing, or how their data could be used against them. My robovac has a LIDAR sensor that maps the house - that's cool - what isn't cool is that by default it uploads those maps to Xiaomi and they can connect it via GeoIP (or GPS if I ever use their app) and have the location and floorplan of my home. I'm not special enough for that information to be very valuable, but it's still super creepy and I would prefer they not have it.
