Question: How do I activate my password with the latest firmware for Hikvision devices?

Answer: The devices need to be activated by creating a strong password. There are four kinds of characters that can be used for password: numbers, uppercase letters, lowercase letters, and special characters. A strong password contains more than two kinds of characters and the password length must be no less than eight characters.
Example: 1234abc+ 
Once the password is strong enough, the activation interface will accept it as valid.
