UniFi Video 3.9.2 Release

by Ubiquiti Employee on ‎02-22-2018 08:06 AM

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


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.
  • 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.
  • 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.
  • 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.



  • 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/v3.9.2/unifi-video.Debian7_amd64.v3.9.2.deb
    sudo dpkg -i unifi-video.Debian7_amd64.v3.9.2.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

  • New version 4.2.13
  • Support for Adaptive Bitrate
  • Fixed crash caused by video settings change
  • Fixed web UI loading with panel overlays




No change: bundled version 1.0.30





  • Added support for improved alerts notifications to the web interface
  • Added support for dynamic bitrate adjustment when live streaming. Should significantly improve live streaming over cloud/WebRTC when enabled.

Security improvements:

  • N/A

Bug Fixes:

  • Fixed duplicate software update notification sent to web interface under certain circumstances.
  • Fixed encoder parameter being ignored by the camera, resulting in higher than expected bandwidth.
  • Fixed database missing index for fetching In-Progress recordings which improves UniFi Video service start-up time.
  • Optimized recording chunk processing to minimize Disk I/O impact on overall NVR system.
    - Improves video cache usage and reduces the system load average. Default video segment length is now also increased from 2 to 4 seconds.



Web Interface


  • Added critical Alerts badge and improved Alerts page presentation.
  • Added recording type column in recording list.
  • (Beta Feature) Added option to enable/disable Adaptive Streaming channels.  (Please see sticky post for more details)
    - We strongly recommend caution enabling Adaptive Streaming on the resolution that you are recording.
    - We recommend enabling Adaptive Streaming for the medium resolution for best live streaming results via mobile over the cloud or remote connections.
  • Updated buffering spinner animation
  • Revamped email templates for local SMTP email notifications.  Cloud alerts will be updated with these new templates at a later date.
  • Reordered camera table columns so that Link State is not obstructed by the camera settings panel and more inline with the OSI model.

Bug Fixes:

  • Made user group permissions required.
  • Updated UVC-G3-Pro rendering.
  • Fixed UVC-G3-Pro touch focus so it only triggers when clicking within the video image.
  • Fixed UVC-G3-Pro inability to select Low resolution within Live View or Live Feed.
  • Added missing 'Don't Change' checkbox for resolution settings when selecting multiple cameras.
  • Made 'Link State' column sortable.
  • Eliminated dual scrollbars in certain views when the window is a lower resolution



  • N/A for the UniFi Video controller software
  • 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.
