Unfortunately, it is not possible to control Vespera from a computer. The instruments can only be operated using the Vaonis dedicated Singularity app. Connecting to a computer is only intended for downloading photos from the instrument's internal memory.
The FTP protocol is available for the following models: Vespera 1 / Vespera II / Vespera Passengers / Vespera X_Edition / Vespera Pro
Vespera III and Vespera Pro 2 can use a USB-C cable.
