. The PI OS install for Raspberry Pi is very simple. Our goal is to install a Raspberry Pi OS Lite (64-bit) image on each device SD card.

Download the Raspberry Pi Imager SW for their website , install and open. You will select your device and then Raspberry Pi OS (Other) Then select Raspberry Pi OS Lite (64-bit)
Then Customization. Very routine information but this is the tricky part. You need the Public Key from your YubiKey to enable SSH Authentication. The imager makes this very easy. Raspberry Pi connect is not installed due to the security implications but is a very interesting tool.

Sensor Requirements

The sensor is based on a Raspberry PI Zero 2W
After PI OS Lite is installed and booted on the device, its only additional requirements are as follows:

First, a clean update

sudo apt update && sudo apt full-upgrade -y

and second,

sudo apt install ffmpeg

ffmpeg is not a small install

Once completed the sensor device can proceed to OS Hardening

The Edge Server will require the following

  1. Motion Application
  2. MariaDB Database
  3. NGINX Web Server
  4. Supporting Video Libraries
