Connect the hotel lobby wifi, can the hotel computer engineer see me and others' WeChat videos? Like video clips?

Usually, the WiFi network in the hotel lobby is a public network, which can be used by all guests, so the hotel computer engineer should not see the content of your WeChat video call with others.

However, if you use the hotel computer or network when using WeChat video call, hotel engineers may see that you are using WeChat video call, but they usually can't see the video content.

Generally speaking, as long as you don't use WeChat video call on the hotel network, you should be able to protect your privacy. However, in order to ensure your safety and privacy, it is recommended that you pay attention to protecting personal information when using public networks.
