Nice, it actually supports several popular Amazon US "no-name" brands, including Imou and Wansview! (Plus, several mainstream Eufy, TP-Link and Wyze cameras are supported by thingino as well.) Seems to be more user-friendly than OpenIPC, too.
More info is at my installers repo https://github.com/wltechblog/thingino-installers or my YT channel (WLTechBlog)
Do you know if Wansview Q5 can be installed easily or not? I think it's one of the only cams on the thingino list that's available in the US with super-fast Amazon FBA shipping for under $20 USD and with lots of stock.
Oh, wait, Cinnado D1 is only $14.99! https://www.amazon.com/dp/B0CBBT5RMP
That's cheaper than Wansview Q5! (Unless the Woot deal returns.)
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?
Frigate is a reasonably immature project but it is getting better with each release. Blue Iris is adored but it does have a Windows requirement so that might disqualify it for you.
