PASSWORD
Strong and unique passwords are crucial to network security. Proper configuration of passwords
and other security settings is the responsibility of the installer and/or end-user.
SETTING A NEW PASSWORD
When you first set up the NVR, you will need to set your own username and password. It is
important that you record these and save them in a secure place for future reference.
•Language: Choose from one of the languages as the OSD language (default, English).
•Device ID: Enter a Device ID (default, 000000). See System Configuration, General Settings on
pg. 221 for more information on the Device ID.
•New Admin Password: Enter your new password. The password must be 8~16 characters,
combining at least 2 different types from among the following: uppercase letters, lowercase
letters, digits, and special symbols. You can view your Password Strength below to help you in
choosing a stronger password.
•Confirm Password: Enter the password again.

•Unlock Pattern: Select Enable to allow unlocking with a pattern unlock. A separate screen will
open to allow you to "draw" your chosen pattern (see Set Unlock Pattern screen).
•Apply: Click Apply to confirm your settings. A Recover Password screen will open allowing you
to set password recovery questions should you forget your password.

•Security Question Configuration: Check this box and choose three security questions using
the dropdown boxes beside each one and type in your answer exactly as you would always
answer it.
•Certificate Of Authorization: If you check this box, you will need to insert a USB drive and
click the Export button to save a secret key to the USB drive that will allow you to reset the
password in the future.
•Super Code: This option would allow the device to be unlocked by a temporary, time-bound
super code generated by an authorized dealer at your request if, at some future time, you were
to forget the password.
NOTE: Since the Super Code option is obviously much less secure, SECO-LARM does not
support this and would not be able to provide a super code.

HARD RESET
If you are unable to reset the password using any of the methods described above, you can reset
your NVR to factory default.
NOTE: Resetting your NVR will restore all settings to their factory
defaults resulting in the loss of all stored customizations, data,
and other settings and should be considered only as a last
resort.
1. To initiate a hard reset, find the reset button on the back just under
the USB port (see diagram, right).
2. Use a small pin or paper clip to press and hold the reset button for 10
seconds until you hear a beep.
