This is project build using “motion” which a software based motion detector. I have created a docker image for this project for portability reasons inside my Pi Zero W.
So what does this project do?
– If you need a surveillance system for your home you can build it yourself pretty cheap using a Raspberry PI and a webcam.
– Configure webcam it to stream and record footage full time or record only when a motion is detected.
– Moreover, this a fun project to run docker on a Pi simply to test docker for Pi Zero.
– This could be run on Pi Zero W/Pi 3/Pi 3 Model B/Banna PI/Orange Pi as well.
What not to expect?
-Well, this is a Pi zero. So, don’t expect it to render 1080p at 60fps. 😛
- Raspberry Pi Zero W connected to your local Wifi network [Raspberry Pi 3 is recommended.]
- Docker 18.06.1-ce installed on Pi Zero.
- USB webcam.
- Sufficient disk space on your SD to store the footage.
- Lots of patience 🙂
Setting up your Raspberry PI:
First, we need to create a folder where we need to store the footage. So, SSH into your Raspberry Pi.
Create a folder where you would like to store the footage. We will be using this folder later to map inside the docker container. Example, create a folder called “surv”.
Unplug any USB devices connected to your Pi, then type in the following:
Plug in your USB webcam to your Raspberry PI Zero, and you should see that the webcam is connected. Below are some sample logs, that I got once I connected the usb webcam:
Additionally, you could run the following to view connected video devices:
v4l2-ctl --list-devices ls -l /dev/video0
You should ideally see the USB webcam in the dmesg logs and in the lsusb outputs.
– Pull the docker image:
docker pull techantidote/motion
To run the docker container, run the following:
docker run -dit --net=host --privileged -v /dev/video0:/dev/video0 -v ~/surv:/footage --name watchtower techantidote/motion motion -n
Here, we are passing the /dev/video0 which the camera attached to the rasbperry pi to /dev/video0.
To view the live stream, open a browser and go to:
If you are testing the configuration, you can try the following:
docker run -dit --net=host --privileged -v /dev/video0:/dev/video0 -v ~/surv:/footage --name watchtower techantidote/motion
Now from inside the container, you can make changes to your configuration files and then start the motion service manually using the following:
service motion start
You can make now changes on the fly and then restart the motion service:
service motion restart
[Note: You may have to restart the docker container “docker start watchtower”]
I have already added the configuration files inside the docker image itself. If you need to tweak the settings such as the resolution/frame rates, you can edit the below two configuration files inside the docker container:
The log files for motion detection are stored in /var/log/motion/logs. If you would to view the log files real time, you run the following command:
docker exec -it watchtower tail -f /var/log/motion/logs
-Running docker inside a Pi Zero for motion detection may not be the best idea.
-Flashing MotionEyeOS which is Video Surveillance OS designed to run on single board computers.
