UNVR Stacking

With stacked UniFi Network Video Recorders (UNVRs), you can dramatically increase the storage retention of a single UniFi Protect camera deployment. System-wide settings, user access, notifications and more can be configured and applied to both consoles automatically.


Before stacking UNVRs, ensure you have the following:

  • One (1) “Parent” UNVR Pro, configured and up to date
  • One (1) “Child” UNVR Pro, in a Ready for Setup / Factory Reset state

Note: Two standard (not 'Pro') UNVRs can also be stacked if both consoles are have a minimum UniFi OS version of 3.1.

How to Stack UNVRs

  1. Connect the child UNVR to the network, and power it on.
  2. Navigate to the Parent UNVR's settings through unifi.ui.com, or by signing in locally.
  3. A prompt will appear at the top right saying a new UNVR has been detected.
  4. Select “Stack” and follow the system prompts to stack your device.

Managing Stacked UNVRs

Cameras initially managed by the Parent prior to stacking don't automatically balance after stacking. You must select the camera and manually reassign it to the Child in the camera’s settings. This is useful to ensure your systems are operating at maximum efficiency.

Note: New cameras added after stacking are automatically balanced and adopted to the least populated console.

Removing a Stacked UNVR

To remove a child console, click on the image of the stacked devices. Select the Child device, and then select to Manage > Remove.

Key Points

Here are some key points to keep in mind:

  • You can only stack two (2) UNVR Pros, or two (2) UNVRs.
  • You can only stack two of the same device; you cannot mix a UNVR Pro with a UNVR.
