DH_NVR5XXX-4KS2 3.216.0006

I downloaded DH_NVR5XXX-4KS2_MultiLang_V3.216.0000006.0.R.20190223 from Dahua wiki and installed on a couple of Non POE 5208-4ks2. it was installed over V3.216.00002..20181106

I had no issues updating and do not see any changes that stand out. Andy said it was mainly for LPR cams..
This is the international version and he said he would put up a new PAL version soon.

Just updated to this firmware, it looks like I've gained ANPR function but IVS no longer works properly.

So is this version and the other version for people detection?

Whats the issue with the IVS? I have not seen any issue with mine but I do set it up in the camera not the NVR.
