 ====== Raspberry Pi Camera on ZoneMinder ======
-===== Install v4l2rtspserver on camera =====
+I spent a lot of time trying to find some good software to run on a Raspberry Pi to turn it into a camera. Even tried to write my own using Perl, but all the libraries are in Python, so it took too much for a simple project.
+I found the v4l2rtspserver (https://github.com/mpromonet/v4l2rtspserver) and decided to try it. The author has a good page, but assumes I knew how to configure ZoneMinder (which was mistaken).
+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.
+===== Configure Raspberry Pi =====
+Enable wlan by adding the following to /etc/wpa_supplicant/wpa_supplicant.conf
+<file>
+country=US
+network={
+   ssid="your ssid"
+   psk="your psk"
+}
+</file>
+Now, do the install
 <code bash>
+# Set up Camera
+raspi-config # go to Interface, and enable camera
+reboot
+ls -lh /dev/video*
+raspistill -v -o test.jpg # Verify camera works
