  Mini-EUSO is a space experiment selected to be installed inside the
International Space Station. It has a compact telescope with a large field of
view ($44 $\times$ 44$ sq. deg.) focusing light on an array of
photo-multipliers tubes in order to observe UV emission coming from Earth's
atmosphere. Observations will be complemented with data recorded by some
ancillary detectors. In particular, the Mini-EUSO Additional Data Acquisition
System (ADS) is composed by two cameras, which will allow us to obtain data in
the near infrared, and in the visible range. These will be used to monitor the
observation conditions, and to acquire useful information on several scientific
topics to be studied with the main instrument, such as the physics of
atmosphere, meteors, and strange quark matter. Here we present the ADS control
software developed to stream cameras together with the UV main instrument, in
order to grab images in an automated and independent way, and we also describe
the calibration activities performed on these two ancillary cameras before
flight.
