The niche of people who actually care about privacy is vanishingly small, and I would hazard a guess that it overlaps strongly with the niche of people who would buy a raspberry pi to tinker with. At this point, we're better off rolling our own with cheap CMOS camera modules, IR LEDs, 3d printed enclosures, arduinos, and rpis. Perhaps there's room in the market for a few people to do this as a side hustle, and sell completed boxes with software for those who don't have time to build their own, but likely not much more than that. Alternatively, any decent A/V store will still sell you wired cameras and base stations that don't connect to the Internet at all. Then your inconvenience is fishing coax or cat5 through the walls of your house.
