System Requirements

  • NVR appliance or a 64-bit OS from the Files section below
  • Intel Atom D2500 CPU
  • 100GB HDD
  • 4GB RAM
  • Google Chrome
  • 500GB HDD or larger
  • RAM Disk for Windows installations - How-To


Important Notes

  • All Linux commands below are for the NVR appliance and Debian 7. Different Linux distributions will have slightly different commands.
  • Updating from a UniFi Video installation prior to 3.3.0 might take an hour or longer, depending on the amount of recordings in the database. To get up and running immediately, perform a clean install instead of upgrading.  This is the last version that will contain this note.
  • Your Ubiquiti Account (SSO) is the same account you use to login to the community forum. If you want to use a different account for UniFi Video, first log out of the community before setting up UniFi Video for cloud access.
  • When adding a new camera, your camera password will be reset and configurable under NVR Settings.  Username remains the same.  This is the last version that will contain this note.
  • Systems that are not the hardware NVR (airVision-C or UVC-NVR) must have some form of an NTP daemon installed to prevent timestamp and time synchronization errors.
  • Email and push alert enable/disable settings are now per-user instead of being system-wide. Alert settings can be found under the "Alerts" tab of each configured user.  This is the last version that will contain this note.
  • Although downgrading is not technically supported, if you do choose to downgrade from a version below 3.8.0, you'll need to factory default your cameras while on firmware less than 3.8.0 in order for the cameras to be managed by controllers less than 3.8.0.  i.e. Downgrade the controller, make sure the firmware on the camera has downgraded to something lower than 3.8.0 (3.7.0 for example), factory default the camera, manage the camera.  This is the last version that will contain this note.



  • Windows: Run Installer as Administrator
  • Hardware NVR/Debian Install manual installation (other Linux files are linked at the bottom of this post, simply change the URL and filename to the appropriate operating system):
    wget https://dl.ubnt.com/firmwares/ufv/v3.9.3/unifi-video.Debian7_amd64.v3.9.3.deb
    sudo dpkg -i unifi-video.Debian7_amd64.v3.9.3.deb 


Cloud Setup

New Installations

  • Visit https://video.ubnt.com using Chrome from a computer on the same network as your UniFi Video installation.


  • Connect to your NVR locally (over HTTPS using the server's IP address on port 7443), then click 'Connect To My Ubiquiti Account' under NVR Settings.



Change Log 

System and Configuration

  • To reduce disk I/O on NVR appliances, UniFi Video logs for all Linux installations are now symbolic links to the data mount point (e.g /srv/unifi-video/logs). They remain accessible from /var/log/unifi-video but are no longer directly written to that partition.


Camera Firmware

  • No change: bundled version 4.2.13



No change: bundled version 1.0.30




  • N/A

Security improvements:

  • N/A

Bug Fixes:

  • Fixed password pattern to allow all characters (including spaces). Only requirement is password length to be at least 8 characters long
  • Fixed webRTC threadpool queue size to allow a system to handle request surges
  • Removed unnecessary set-nvr-disconnect-notifications cloud
  • Disabled AV cache usage monitoring on Windows. If a RAMDisk is installed, the following can be added to your system.properties file to monitor the RAM disk usage: app.av.cache.space.check=true


Web Interface


  • N/A

Bug Fixes:

  • Fixed MediaSource buffer and segment size to trigger hardware acceleration when streaming live video



  • Minimum value for 'Minutes Between Alerts' for standalone SMTP settings is 5, this should only be applied for Cloud connected installs.  We have already fixed this and it will be included in the next version.
  • We are aware of some issues with the iOS app and are addressing it by rolling back to a known working version on as many models as possible.
    - iPhone X users will continue to experience audio issues for the time being, we will be working as quickly as possible to resolve this as well as incorporate the full support for new camera models.
