I find the LTS firmware numbering confusing. The firmware on the LTS web site is the same version as what's in my NVR, but a newer build number. (NVR has V3.3.6 build 160105, web site has V3.3.6 build 160810). Is it worth reloading for a newer build of the same version? Do the LTS version numbers track the Hikvision numbers? If they do, then the above referenced Hikvision 3.4.80 isn't available from LTS for my 8916 NVR.
Added on edit:
The good news: I upgraded to the latest firmware build. Initiating it via the web interface was easy and worked flawlessly. There is nothing at all in the manual about upgrading firmware via the web interface.
The bad news: Nothing about the timeline presentation changed. Showing events on the continuous record timeline is something I would expect to be a very basic requirement for even a low-end security recorder. And with the 3 interfaces, it all works differently:
Head interface: All events are accessible on a list. They are not shown on the timeline if using continuous record.
Web interface: Events are not accessible at all if using continuous record.
PC interface: Some events are accessible on a list. No obvious pattern as to which are and which aren't. Not shown on timeline if continuous record.
I'm pretty disappointed with this "Platinum Enterprise Level" NVR right now. If I find out it's user error I'll correct my outburst.
