Wow, 3 times factory reset twice ?! Should we spin around the camera three times and make a special reset dance in front of it ?!
I agree with you, and even if I found the 4K-T a bit laggy (especially with higher resolutions), I'll keep the initial firmware for now as tripwire works fine and local SD card storage records correctly. (Surprising to read that I should use Internet explorer to have a quicker video player...) (unclear how it ended for you,
@mephisto_uk)
It comes from the developers that get "under the hood" of the firmware and have seen in some instances it takes multiple factory resets for the firmware to take properly.
It doesn't mean that people haven't had issues by just updating it directly without doing it, but if people have problems, we typically find they did not do a factory reset first and when they follow this procedure, it then takes and works.
Same with Explorer. While newer cameras are supposed to work with other browsers and not need the plug-in nonsense, keep in mind to ensure full compatibility, IE is still preferred. And this isn't specific to just Dahua either. And sometimes the plug-in nonsense is needed.
It comes down to IE was the most popular browser when these cameras started to be made, so they centered the firmware around one particular browser and they got lazy and never updated the internals of the program to play nice with other browsers as more became available and IE started to fade.
Back when the firmware was written, it was probably a pain to get it to play nice with every different browser, so they went with the most popular one.
They haven't had a need to address this because their intended market (remember it isn't us) is mainly businesses where they have enough light they can stay in default settings so they don't have a need to login to the camera via browser. It is us homeowners that push these to the limits and actually change settings.
As long as their intended market simply uses the NVR as a recording device and to display it on a monitor, they have no need to change what works for their intended market.
Further, Steve1225, who is an installer and works closely with Dahua, said it best here in this
post:
Even though Microsoft has sunset Explorer, it is still available in Windows 11 (hidden). Many older programs rely on the old Trident (HTML-) Engine from IE, even stuff as basic as the old Control Panel. Old browsers are old, so unlike modern browsers where the WebView can be its own component, it's either all or nothing. And since the engine is still required not to break Windows functionality and apps from before 2015, it's still included (but mostly hidden). The whole file manager system is still based on IE. That's also why Device Manager and Control Panel are still there too. Similar to Dahua and Hikvision, Microsoft changed the UI and not the core, and added new features to upgrade its OS. A lot of legacy stuff are hidden.
So contrary to popular belief, Internet Explorer isn't going away anytime soon.
YMMV
