Video streaming vs wifi vs 4G

Hello everyone. I have a sever blynk location with rpi, as well as 3 cameras synchronized in the blynk app. But there is a small problem, when connected by 4G they consume a lot of mobile data. :frowning: So I wanted to ask the following: There is some form (widget) where you can enable or disable streaming the application. Because whenever I enter the app, streaming starts to work. I wanted to enable / disable streaming whenever I wanted. Thanks
