If you want to see each other through their cameras without their knowledge, do you have such software?

If you want to watch the video without telling him, it must be voyeurism. Go find voyeurism software, which is usually brought by Trojan horses.

Watching the other party through the video also spread to the internet, and the other party knew that it would call the police in the future. He saw it with peeping software.

If he doesn't accept it, you won't meet. There is no other way but to peek at the software. Give him a Trojan horse, and you can see him through his camera.
