Object Detection at the Edge


Install the following tools on your Edge device: Docker and docker-compose. Use the following links to help you:

My Edge device is currently running Fedora 27, with the following versions of the abovementionned packages:

  • Docker version 18.02.0-ce, build fc4de44
  • docker-compose version 1.19.0, build 9e633ef

We use IP cameras from SV3C, more specifically the POE models (that can do 1080p):

Getting ready

  1. Clone this repository locally: git clone
  2. Make sure Docker is running: sudo systemctl start docker
  3. Put yourself in the cloned folder: cd video_detection

Note: you do not need to need to build any Docker container. It will be built automatically for you if not yet available. See the build instruction in the docker-compose.yml file.

Running the Object Detection on the Edge device

Note: unless you have installed Docker and performed these post-installation steps, you will need to use sudo to use docker-compose. For some reason, it does not find the docker-compose executable and I have to use the full path to it, i.e. sudo /usr/local/bin/docker-compose up (to be investigated later, or maybe a reboot will solve it).

  1. Set-up the IP camera following the online User Guides
  2. Take note of the IP address assigned to the camera

We use an environment variable to pass the IP address of the camera to the container that will capture the video stream. The name of the variable is IP_CAMERA. 3. Start the Object Detection service

sudo IP_CAMERA= /usr/local/bin/docker-compose up
  1. Open a broswer at to see the results

Notes about running on Clear Linux

It is possible to run the same set-up on Clear Linux. Unfortunately, it is not possible to use Clear Containers for this yet (a bug has yet to be filed).


Same as for Fedora 27 (or any other OS really), install Docker and docker-compose. Use the following guides to help you:

$ sudo curl -L`uname -s`-`uname -m` -o /usr/bin/docker-compose
$ sudo chmod +x /usr/bin/docker-compose

Because of the current issue with Clear Containers 3, we have to change the default behaviour of Docker when running in Clear Linux (bare metal). The background is that, by default, it will pick the Clear Containers 3 runtime (cc-runtime) when running bare-metal so we need to force the system to not do that.

One way to achieve this (not sure whether it's the best way) is to modify the docker.service file (/lib/systemd/system/docker.service) and change the ExecStart line to this:

ExecStart=/usr/bin/dockerd --storage-driver=overlay2 --default-runtime=runc

Now reload and restart the daemon:

$ sudo systemctl daemon-reload
$ sudo systemctl restart docker

Verify that the runc runtime is being used:

sudo docker info | grep Run
