Answer

It is desirable to make dua when one sees the House of Allah.

Saaidun Hudaifa Ibn Aseed Radiallahu Anhu narrates that the Prophet of Allah Sallallahu Alahi Wasalam used to make dua upon looking at the Kabah saying, “O Allah! Increase the honor, status, and magnitude of your house”. (Tabarani)

Seeing the House of Allah is also a very blessed action, however, the reward is based on the actual seeing (ru’yah) of the House and not by watching it on the television or internet.
