I’ve looked in Pamac, in the all category which includes repositories, flatpak and AUR, and nothing…any idea on how to install it? i want to connect a Sony a6000
This is the official site and it’s supposed to be open source: https://digicamcontrol.com
The packages name is digikam.
It is in extra/digikam.
But what you linked to is not that.
It appears to be a Windows only program.
Open Source doesn’t mean Linux…
Reading the first paragraph:
Control your camera settings remotely from your Windows PC via USB.
I think that’s a clue 
this isn’t Digikam.
When I can’t find something using pamac (which also searches AUR). I’ll head over to alternativeto.net. When I find something, I come back and search Manjaro repositories. If I absolutely need it, I’ll install from AUR. But I try not using the AUR.
Searched: alternative to digiCamControl, opensource, linux
arch also has a list of applications: List of applications - ArchWiki
You can try entangle, available in AUR and as flatpak. Therefor you must enable flatpac in settings of software under third party.
I hope I’ve retranslated it correct from german.
But you will find it.
Oh ok…thought there would be a linux version…thanks for the options…i’ll try them cause wanted to connect my a6000 for streaming without a cable…and it appears that Digicam does that…but, anyway…will let you all know what happens with my experiments 
Also, does anyone thinks it could work with bottles or something like that?
