Most of their IDEs you can use for free for non-commercial purposes and even if you need to buy them; when you compare software development to any other profession our tools are incredibly cheap.

This still fundamentally suffers from the oracle problem like all blockchains solutions. You can always attack these blockchain solutions at the point where they need to interact with the real world. In this case the camera is the “oracle” and nothing prevents someone from attacking the proposed camera and leveraging it to certify some modified footage. The blockchain doesn’t add anything a public database and digitally signed footage wouldn’t also achieve.
