The licensing on this project is wonky. They have an MIT license, but then they say you can't use the software for commercial purposes without contacting them. That's in contradiction to an MIT license. An MIT license is basically "use it for anything". If you don't want that, then use some kind of "copyleft" license for non-commercial users, and specify separate commercial terms for users who want to keep closed source with their modifications.
Are you a representative of a camera installation company or do you sell services? Please do not distort the information that is written on the site. And it says there that the project ASKS everyone who uses the firmware for commercial purposes to contact. You are simply confusing MIT with real life realities.
