Setup

Follow this guide to set up your system to run the ONVIF Device Service.

System Requirements

Intel™ Core® processor
Ubuntu 20.04.4 LTS or later
ONVIF-compliant Camera

Note

The instructions in this guide were developed and tested using Ubuntu 20.04 LTS and the Tapo C200 Pan/Tilt Wi-Fi Camera, referred to throughout this document as the Tapo C200 Camera. However, the software may work with other Linux distributions and ONVIF-compliant cameras. Refer to our list of tested cameras for more information

Other Requirements

You must have administrator (sudo) privileges to execute the user guide commands.

Dependencies

The software has dependencies, including Git, Docker, Docker Compose, and assorted tools. Follow the instructions below to install any dependency that is not already installed.

Install Git

Install Git from the official repository as documented on the Git SCM site.

Update installation repositories:
```
sudo apt update
```

Add the Git repository:

sudo add-apt-repository ppa:git-core/ppa -y

Install Git:
```
sudo apt install git
```

Install Docker

Install Docker from the official repository as documented on the Docker site.

Verify Docker

To enable running Docker commands without the preface of sudo, add the user to the Docker group. Then run Docker with the hello-world test.

Create Docker group:
```
sudo groupadd docker
```
Note

If the group already exists, groupadd outputs a message: groupadd: group docker already exists. This is OK.
Add User to group:
```
sudo usermod -aG docker $USER
```
Restart your computer for the changes to take effect.

To verify the Docker installation, run hello-world:

docker run hello-world

A Hello from Docker! greeting indicates successful installation.

Tool Descriptions

The table below lists command line tools this guide uses to help with EdgeX configuration and device setup.

Tool	Description	Note
curl	Allows the user to connect to services such as EdgeX.	Use curl to get transfer information either to or from this service. In the tutorial, use `curl` to communicate with the EdgeX API. The call will return a JSON object.
jq	Parses the JSON object returned from the `curl` requests.	The `jq` command includes parameters that are used to parse and format data. In this tutorial, the `jq` command has been configured to return and format appropriate data for each `curl` command that is piped into it.
base64	Converts data into the Base64 format.

Table 1: Command Line Tools
