https://felenasoft.com/xeoma/en/contacts/Cameras in Xeoma can be added via '+' menu - Simple search for local cameras (if cameras are in your local network)
or using '+' - Search by ip/password - specify ip address of the camera, login/password and port (if it's a default 554 or 80 port, you can leave this field blank)
You need to make sure that your camera can be seen in browser using its ip address (
