Can Genius Vision offer technical support over AplusView software?

No.

AplusView software technical support to their users is conducted by Asoni. When there was still a valid contract between Asoni and Genius Vision, some technical support of the rebranded AplusView software is offered from Genius Vision to Asoni (and Asoni, in turns, offers their support to their customers). However, Genius Vision did not directly reach to AplusView's users.

As this article suggests, Genius Vision and AplusView should be considered as different software. The ways to request for technical support are different. Genius Vision technical support are offered exclusively to Genius Vision NVR software users.
