Microsoft now loves MS Edge as much as loved MS Internet Explorer years ago and switch IE to Edge form time to time.
But HiWatch still love MSIE - you cannot watch cameras in any other browser.
It is annoying thing in W10, but it become a nightmare in W11 - you even cannot find how to run IE.
You can create vbs file to run IE -
CreateObject("InternetExplorer.Application").Visible=true
Took from here
