 Anyway, no GUI needed, so I did the Raspberry Pi OS Lite (https://www.raspberrypi.org/software/operating-systems/) and set it up, then did the following. Ended up with a pretty decent camera that is not "phoning home" with all your images.
+===== Get raspbian image onto SD =====
+  - Download the Lite version of Raspbian from [[https://www.raspberrypi.org/downloads/raspbian/]]
+  - write the downloaded image to the micro-sd (do not uncompress)
+  - mount /boot from SD onto /mnt
+<code bash>
+touch /mnt/boot/ssh # enable ssh
+# only do the following if you need wifi. Change country code, ssid and psk for your system
+# see [[https://www.raspberrypi.org/documentation/configuration/wireless/headless.md]]
+cat <<EOF >/mnt/boot/wpa_supplicant.conf
+ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
+update_config=1
+country=<Insert country code here>
+network={
+ ssid="<Name of your WiFi>"
+ psk="<Password for your WiFi>"
+}
+EOF
+</code>
+Insert SD into your Pi and boot up.
