I told you it could be a browser issue LOL
While it is weird to us that they use a no longer supported browser, but there is a reason...
Many manufacturers have focused the firmware around Internet Explorer (which was the standard once upon a time), even brand new cameras unfortunately. Keep in mind we are not the intended audience of Hikvision and Dahua, it is professional installers with specialized equipment and/or don't update their equipment, so they are not going to invest in changing the firmware until they see a need. As such, those end users usually don't get into the userface like we do. If you try to call Dahua they will tell you to pound salt and talk to your installer.
So until their professional installers and their intended market demand or require it, we won't see it and us complaining they don't care because we are not their intended market. They are not going to reinvent the wheel and throw put all firmware and start new until there is a need.
We are just fortunate to be able to get our hands on these cameras. And then a forum like this to help us set it up!
