I have the impression that most security cameras on Amazon are subsidized with their subscription services.
Also, because many of these brands are no-name, you get the inverse volume discounts — you can get 1 camera for less per-unit cost compared to buying 2 or more.
Starting a business may make more sense if you're willing to go directly to the manufacturer, and have the manufacturer flash the firmware directly at the factory. Even then, why would people buy from you at $30 when they can buy an encumbered version for $15 and follow a few instructions?
