Reference Manual ATOM one 4K mini

1 Overview

This manual describes the usage of the ATOM one 4K mini camera system.
The general operation of the device is described in chapter 2. Information on firmware
updates is found in chapter 3.
We provide an open-source, free of charge GUI application which gives easy access to
most camera functions, for more details on the GUI see chapter 4.
Chapter 5 and 6 describe how to connect with the device and how the settings on the
device are handled using terminal commands.
For details on the camera functions, please refer to the API chapters of this manual which
start with chapter 7.
