\section{Hardware}
Discussed in this section are some of the hardware options to be
explored. More explicit instructions of a particular hardware installation
can be see in \ref{sec:hardware-overview}, page \pageref{sec:hardware-overview}.
Below is discussed camera options, for details on computers and other parts,
also see the Hardware chapter.
For the purposes here, are three main categories of hardware. Depending which
category of equipment is selected, it impacts everything else, such as the
software used. Main categories:
\begin{itemize}
\item Motion video cameras --- Moving images.
\item Still camera --- Still photos.
\item Allsky cameras --- Views of all, or nearly all of the sky.
\end{itemize}
Different types of equipment can be used in different categories.
Some can be used in multiple setups, most just in one.
If available, using motion video cameras will work best for
detecting \glspl{satellite} with the developing \gls{SatNOGS} toolchain.
Examples of motion video camera sources that could be used:
\begin{itemize}
\item The Imaging Source Cameras based on IMX174 --- Known to work. Recommended.
High quality cameras, believed to be usable following \gls{DFSG}.
\item ZWO ASI based on IMX174 --- Known to work. Not \gls{DFSG} compatible.
Uses proprietary SDK. Currently in prototype development.
\item UVC/Video4Linux2 --- ``Any'' video camera that works with the \gls{Linux} kernel.
Typically, the device will appear similar to \texttt{/dev/video0}. A camera
that works with the software isn't necessarily sensitive enough to detect
satellites, however, as most are designed for bright environments.
\item OpenCV --- Devices that work with OpenCV can be used.
To work well, they need to be sensitive.
\item Raspberry Pi --- The PiCamera can be used. A good lower cost option.
Recommended. Many non-Raspberry Pi devices are also compatible with the Pi
MIPI interface.
\end{itemize}
Still cameras can also be used productively. The current \gls{Python} toolchain
is in very early development and not completely usable yet.
See the list below for still camera options:
\begin{itemize}
\item \Glspl{telescope} --- Can definitely take images of \glspl{satellite}.
Not the best tool at present, as it isn't well integrated into the toolchain.
The \gls{FOV} is generally too small. The mounts are optimized for
different types of tracking than satellites. This is changing, and longer
term could be well-supported. Using \gls{RASA} style \glspl{astrograph}
is likely the best option.
\item \gls{INDI} --- Typically used for control of \glspl{telescope} and
associated instrumentation, such as tracking mounts and cameras.
Cannot be used directly with the current developing \gls{SatNOGS} toolchain.
It is not seen as the future path forward as it isn't well optimized for
\gls{SatNOGS-Optical} usage. That said, it is very useful at present for
running a tracking mount with KStars and Ekos, for example,
in lieu of a better option. Camera software in the \gls{INDI} platform typically
produce image \gls{FITS} files.
\item gphoto --- The \gls{Linux} kernel recognizes many cameras that can be
used with gphoto tools and drivers, available in \gls{Debian}.
This is the recommended option at present for still cameras.
\gls{DSLR} cameras, such as from major manufacturers Canon and Nikon, are
used with gphoto.
