UNVR Stacking

We strongly discourage stacking UNVRs; instead, we recommend employing an ENVR and/or take advantage of Vantage Point if more space/power is needed. Stacking UNVRs is possible, but some key features won't be available across both consoles within a stack, due to resource limitations on the parent console.

Requirements

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.

ENVRs cannot be stacked. Use Vantage Point instead for a scalable experience.

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:

1. Open UniFi Protect
2. In the dashboard, click on the Second UNVR
3. Open the Manage pane by clicking the "⌄" icon
4. Select Remove.

Stacking Limitations

There are certain limitations to stacking: 

• Stacking only supports two (2) UNVR Pros, or two (2) UNVRs.
• Moving a camera between the child and the parent will erase all prior recordings. 
• Face recognition and LPR are not supported on cameras on the child console. 
• Vantage Point is not supported with stacked consoles. 
• AI Key and AI Port and only supported with cameras on the parent console. 
• Pairing cameras with sensors and access hubs is only supported on the parent console
• It’s not possible to access the child NVR directly. If something happens with the parent console, the user is locked out of the child console.
