by Ubiquiti Employee on ‎03-28-2018 02:35 PM

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
  • 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
  • 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



  • 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/v3.9.5/unifi-video.Debian7_amd64.v3.9.5.deb
    sudo dpkg -i unifi-video.Debian7_amd64.v3.9.5.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 

Camera Firmware

  • No change: bundled version 4.2.13



  • No change: bundled version 1.0.31




  • N/A

Security improvements:

  • N/A

Bug Fixes:

  • Fixed an error in motion recording that caused Minimum Motion Event Trigger content to be truncated for short recordings
  • Fixed motion recording playback sometimes including an extra video segment
  • Fixed motion images sometimes not included in alert emails
  • Fixed cloud disconnections caused by websocket pong timeouts, when network is slow or cloud server responses are slowed down.  This solves the repetitive disconnected/reconnected cloud issue.  If your UniFi Video install continues to be disconnected after upgrading, it should come back to a Connected status in 15 minutes or less
  • Fixed Email username field not populated correctly
  • Fixed UniFi Video cloud re-connection hanging after the controller is disconnected either due to degraded network or the UniFi Video installation losing its IP address


Web Interface


  • N/A

Bug Fixes:

  • Fixed motion recording length rounding down by 1 second (e.g 9:59 instead of 10:00 minutes)




  • Expanding a single live view from a matrix results in stuttering video (investigating)
  • Minimum Motion Event Trigger (MMET) is not accurate in some cases which leads to false positives. We are currently testing an improvement after fixing a bug in the camera firmware
  • Minutes between alerts for non-cloud connected installations has a minimum of 5 minutes.  We are evaluating the most intuitive way to handle the various scenarios of upgrades and switching between cloud and non-cloud connected systems
  • We are aware of some issues with the iOS app and have addressed 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 in the form of iOS App updates.
