1) Most important! No horrible Hikvision attitude
2) Better ONVIF support
3) I actually prefer some of their cameras (HDW-4300C for example is much better IMHO than DS-2CD2332-I or DS-2CD2342WD-I)
4) Quieter NVR!
5) No firmware bricking camera issues
6) I think Dahua app is just as good as Hikvision app for mobile
So I'm voting with my feet and my money, not sure what plan is yet. Might be a Dahua / other make combo.
In the meantime I'll still recommend Hikvision (mainly from AE) for newbs as it's still better than complete junk and I'll still help those who brick their cameras when Hikvision won't.
