Last week I purchased Raspberry PI Infrared IR Night Vision Surveillance Camera Module 500W Webcam. This webcam features 5MP with OmniVision 5647 sensor which is in fixed focus mode. The high-definition 5MP camera delivers outstanding photos but can also shoot video, ideal for drones or a CCTV project. The camera overcomes the disadvantages offered by our other Raspberry Pi Cameras as it has provision for night surveillance too.
It cost me 1190 bucks (INR) and took just 3-4 day time to arrive. This Raspberry Pi Camera Module is a custom designed add-on for Raspberry Pi. It attaches to Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data.
Under this blog post, I will showcase how to install the latest Docker 18.09.0 on Raspberry Pi. I will test drive BuildKit on top of this credit-card sized device and finally showcase how to turn this small Pi into low-cost HD surveillance camera using a single Docker Image.
Pre-requisite:
Hardware:
- Raspberry Pi 3 ( You can order it from Amazon in case you are in India for 2590 INR)
- Micro-SD card reader ( I got it from here )
- Any Windows/Linux/MacOS
- HDMI cable ( I used the HDMI cable of my plasma TV)
- Internet Connectivity(WiFi/Broadband/Tethering using Mobile) – to download Docker 18.09.0 package
- Keyboard & mouse connected to Pi’s USB ports
Software:
- SD-Formatter – to format microSD card (in case of Windows Laptop)
- Win32DiskImager(in case you have Windows OS running on your laptop) – to burn Raspbian format directly into microSD card.(No need to extract XZ using any tool). You can use Etcher tool if you are using macbook.
Steps to Flash Raspbian OS on Pi Box:
- Format the microSD card using SD Formatter as shown below:
2. Download Raspbian OS from here and use Win32 imager(in case you are on Windows OS running on your laptop) to burn it on microSD card.
3. Insert the microSD card into your Pi box. Now connect the HDMI cable from one end of Pi’s HDMI slot to your TV or display unit and mobile charger(recommended 5.1V@1.5A).
4. Let the Raspbian OS boot up on your Pi box. It takes hardly 2 minutes for OS to come up.
5. Configure WiFi via GUI. All you need is to input the right password for your WiFi.
6. The default username is “pi” and password is “raspberry”. You can use this credentials to login into the Pi system.
7. You can use “FindPI” Android application to search for IP address if you don’t want to look out for Keyboard or mouse to search for the right IP address.
Enable SSH to perform remote login
To login via your laptop, you need to allow SSH service running. You can verify IP address command via ifconfig command.

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run
containers which can be used to obtain root privileges on the
docker host.
Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface

We have reached finally to the interesting topic of this blog post. Now we are going to run a Docker container which runs CCTV surveillance software – all with a single-liner CLI.
Cloning the Repository:
$ git clone https://github.com/collabnix/docker-cctv-raspbian
$ cd docker-cctv-raspbianBuilding the Docker Image
docker build -t collabnix/docker-cctv-raspbian .Configuring Camera Interface
Before you execute run.sh, you need to configure Camera Interface by running the below command:
# raspi-config
It will open up command-line UI window, choose Interfacing , select Camera and enable it. Save and exit the CLI window.
Running the Docker container
Before you execute run.sh, you will need to load the required driver “bcm2835-v412” to make your camera module work. If you miss this step, you will end up seeing a blank screen even though the application comes up without any issue.
root@raspberrypi:~/rpi-motion# sudo modprobe bcm2835-v4l2
root@raspberrypi:~/rpi-motion# ls$sh run.shThat’s it. Browse over to http://192.168.1.5:8082(either using Win Laptop or macbook) to open up CCTV cam which initiates the video streaming instantly. Cool, isn’t it?
To summarize – Docker containers can make it really easy to turn your Pi box into HD surveillance camera in just few minutes. In my future blog post, I will bring up more exciting use cases around Docker and Pi. Stay tuned !
