Post cameras IP addresses from USA, maybe someone will come in handy, or someone wants to be pampered.
I have not checked the passwords.
Try the factory setting for this type of camera (login: admin password: 12345; 1234; 0000; 111111; 888888; 000000;999999), from practice - most users do not change the factory logins and passwords on their devices.
You can try bruteforce, in 90% cases login: admin, and passwords consist of one digit in the range of 4 to 6 characters.
