is there a default license and if yes what is its capacity ?what license used for in cloudivs ? What is the basic features come with license

No, but we can apply for a temporary trial license, valid for up to 90 days. If there is no license, we can only try the basic live and video functions

Licenses simply release your work into the public domain or grant permissions to individual copies. It also means that you have given up copyright income, and there is no obligation to list you as an original author or contributor. Open source license agreements are easier to contribute to others without having to seek special licenses. It also protects your rights as an original, at least confirms your contributions.

All functions are implemented through licenses. By default, the basic video surveillance function is free of charge.

If you have any questions, welcome to reply and exchange, looking forward to your reply and good comments. thank you.
