This would be an attractive solution but none of the user agents worked for me. I have one camera - DS-2CD2543G0-IS - [out of 8] which has always showed live feed and config previews in Safari but the rest are untouchables, even though they mostly have a more recent firmware update than the DS-2CD2543G0-IS.There is second solution for this problem (if there is no a newer firmware for that HIK cam/nvr) - use developer mode in Safari (Preferences -> Advanced -> Show Develop menu in menu bar) and set User Agent to Google Chrome or Firefox (Develop Menu -> User agent -> Google Chrome). After this the original firmware on Acusense G2 (before firmware upgrade) showed me working Live View in Safari on Mac.
Is the latest version of Safari (13.0.5) on MacOSX Catalina?This would be an attractive solution but none of the user agents worked for me.

I'm actually using Safari v13.1 on High Sierra [Os 10.13.6].Is the latest version of Safari (13.0.5) on MacOSX Catalina?
Only a cable, a POE switch, the router and the dreaded iVMS-4200. I don't use an NVR.Is there any router/firewall/NAT between You and cams? Are the cams connected to NVR POE ports?
At this moment I have AcuSense NVR (7616-NXI-I2/S4) which don't support Live View without plugins on any browser (there is no web socket function in this model - I don't known why????). I wait for replacement for classic I-series model (7616-NI) so I can confirm/deny is the classic I-Series NVRs works under Safari.Thanks for the advice @steve1225
But the specific issue here is the stability issue for accessing an I-series NVR on a Mac and I can confirm to you from our testing that all the things you mention above do not work for the I-series NVRs, especially the Developer/user agent setting which is something we tried long before Hikvision started introducing a 'Plug-in free' solution and we tried to use Safari with the user agent set to IE and it made no difference (as @macman says) because Hikvision then and still now do not have the software/plug-in to install on the MacOS that fully supports their camera/NVR software and so although now with the latest NVR & Camera firmware you can get a live view image and control camera/NVR settings, there are still lots of menus, settings, and buttons that are missing when viewed on a Mac through any browser.
I have remote access to new G1 cam (from ColorVu line) and this cam also works under Safari for me. I attach pics from live view + system info + display settings. So HIK have working live view in latest Safari - there can be older fw's for some cam models which have older Java Script and simply don't validate Safari as valid browser with working WebSockets.When v5.6.x and v4.22.xxx firmware were introduced for the G1 cameras and I-series NVRs they added a Download Plug-in button when accessing from any browser, installing this is what drastically improved the Chrome & Firefox browser compatibility and we know this because we have installed it on a PC and Chrome/Firefox run better now on a PC, but when you try and download this from a Mac browser the file is still .exe file which cannot be installed and so that is the thing we have been chasing for Hikvision to update.
Also, I should add that the G2 AcuSense camera you have actually uses a completely different firmware and is newer software & hardware than the majority of the G1 cameras so it may be that Hikvision has already introduced changes in those cameras that makes them more stable on modern browsers, hopefully, this improvement for the AcuSense cameras is what will be applied in this new v4.40 firmware coming in May but as always with Hikvision we will have to wait and see if it makes any major difference.
