Do any of you know how to receive notifications by email or sms (or alarm outputs) about a user logging in remotely to a Dahua or Hikvision recorder? Can any of you have a working solution?
Well, if you can't drag the water to the sea, drag the sea to the water
You may (or may not) be aware of API interfaces on Dahua (and probably Hikvision):
GetActiveUserInfoAll

You can "query" your device every 1s and work around that information for sms/mail information.
