UniFi Video Server as a LXC Container on Proxmox

To be clear, UniFi Video. Not UniFi Protect,
Specifically tested with:
ENV: Unifi-Video 3.10.10-3.10.12 on Ubuntu 18.04.xx LTS as a LXC Container on Proxmox 6.2-4.

Build:
Basic Container Build with the following specs
Unprivileged
6GB Boot
Spec’d mount point for video storage needs: mp=/var/lib/unifi-video/videos
(300GB gets me around 11-12 weeks / 6 cameras on Record Only Motion Mode)
2 Core minimum / which should sustain to 12 Cameras
1GB RAM / per / 6 Cameras
0.5GB Swap / per / 6 Cameras

Configure:
Set Proxy and tz:

#!/bin/sh
printf 'Acquire::http::Proxy "http://<squid>:3128/";\nAcquire::https::Proxy "http://<squid>:3128/";' >> /etc/apt/apt.conf.d/proxy.conf

ln -sf /usr/share/zoneinfo/<country>/<area> /etc/localtime
date

Update and install basics:

apt clean all
apt update
apt dist-upgrade
apt install vim ncdu htop

Though mongodb, mongodb-server, openjdk-8-jre-headless and jsvc are required; by installing the deb file then fixing dependencies all of the required packages are installed and if at a later date they are not required they can be easily autoremoved.

Camera setup and everything else is not covered here.

Able to check for updates by going to this url, https://community.ui.com/tags/unifi-video and checking the “Latest UniFi Video Software Releases” section for new version changelogs.

Personally with cameras around my home I prefer not to have any of it open to the internet. All my cameras and recorder are on a firewalled subnet/vlan. Using a togglable rule in pfsense I enable and disable the recorder to access the proxy when running updates.

The only other firewall rules to keep in mind are NTP access to port 123 on pfsense so the recorder and cameras can keep accurate time, and the recorder access to DNS on the firewall for updates.
