Get over OCD and either accept it or not use better cameras LOL.
These security cameras are not very secure (ironic isn't it), and they don't use HTTPS or other security measures, which is why we say and preach do not allow these cameras to touch the internet.
But don't be fooled by consumer cameras like Ring and Blink that this message won't pop up because they have a whole other host of vulnerability issues.
Plus it is best to use Internet Explorer for these cameras, yeah we know LOL, but it also isn't as sensitive to these things, in addition to potentially giving you access to more menu options.
