Overview

This article explains how to reset an NVR Appliance to its original factory settings.

NOTES & REQUIREMENTS:  The following guide is based on UniFi Video version 3.1.x and later. Factory resetting an NVR will remove all previous management settings and video data. Any custom configuration changes applied by the system administrator will be lost, such as file-systems mounted on iSCSI volumes or locally attached external disk drives. The default IP address of the NVR appliance is 192.168.1.30 (but will retrieve a DHCP-assigned address if a DHCP server is present).

Introduction

Back to Top

There are three methods to factory reset your NVR: via Graphical User Interface, Command Line Interface, or the reset button on the actual device. 

Graphical User Interface (GUI)

Back to Top

1. Open the NVR landing page in a browser (http://<NVR_APPLIANCE_IP>/). You do not need to include the default port "7443" as the NVR hardware itself is what will be managed, not UniFi Video.
   
2. Click on the gear icon on the upper right hand corner of the page to access the Configure Device page.
3. Log in as "root" system account (username/password should be either ubnt/ubnt or root/ubnt). If you've changed this password, and don't have it anymore, proceed to the Hard (physical) reset method.
4. Navigate to the Maintenance tab.
5. Click "Reset to Defaults" button next to "Reset To Factory Defaults:"
   
6. Re-open the NVR landing page in a browser (http://<NVR_APPLIANCE_IP>/).

Command Line Interface (CLI)

Back to Top

1. Open a shell session to the NVR appliance e.g. ssh root@<NVR_APPLIANCE_IP>
2. Enter the following command-line
   nvr-systool reset2defaults
3. Re-open the NVR landing page in a browser (http://<NVR_APPLIANCE_IP>/).

For more options, type nvr-systool --help to list other administrative parameters. The nvr-systool is used by the NVR management console where this CLI approach is equivalent to the GUI steps.

Hard (Physical) Reset

Back to Top

1. Press and hold the Reset button (the crescent moon button) located below the Power button for 10+ seconds. The device will take up to 60+ seconds to restore the default configuration and return to the original factory version.
2. Re-open the NVR landing page in a browser (http://<NVR_APPLIANCE_IP>/).
