Could I just double check this with you with respect to the NVR?
I was reading this post:
Finding the Latest Hikvision Firmware for your NVR
and it would seem that my NVR model is listed under one of the other firmware versions:
76/77 || NI-E1/E2/E4 (E Series)
If I then search for firmware for that model on the EU hikvision portal I get a list of the following firmware versions
V3.4.80 build160718 English+Multi-lingual - 2018-12-23
V3.4.82 build160818 - 2018-12-23
V3.4.90 build161008 - 2018-12-23
V3.4.91 build161220 - 2018-12-23
V3.4.92 build170228 - 2018-12-23 <<<<< Has release notes
V3.4.95 build170626 - 2018-12-23
V3.4.96 build170921 - 2018-12-23
V3.4.97 build171031 - 2018-12-23
V3.4.98 build171121 - 2018-12-23
Most of them don't have any release notes but one of them does (see above). If I look at the release notes for the supported product list, then my NVR appears to be listed?
So what is the difference between the DS-76xxNI-E1/4P/A and the DS-76xxNI-E1-A?
Also my NVR is running V3.4.98 build 171121 which seems to be the latest according to the EU portal but looking at the UK portal for the equivalent firmware, it's shown as V3.4.101 build181024..
All very confusing?
