Password Rule

Summary
To ensure the highest level of protection, LTS has launched a new login procedure
that requires users to create a new password for the admin account upon the first login to
all devices. The password must contain 8 to 16 characters, combining numbers,
lowercase letters, uppercase letters, and special characters. 
At least two types of the above-mentioned characters are required to activate the device.

The system will check the password strength; 

“Risky” passwords will not be accepted (no bar).

 For the latest DVR/NVR/IPC firmware.
The password can not contain the User Name inside.

The IP cameras starting with firmware v5.3.0 WILL NO LONGER HAVE A DEFAULT
PASSWORD.
