How to get alarms from Hikvision IPCamera

[smontoya]

Hi all,
I have an Hikvision IP camera DS-2CD2120F-IW model with firmware v5.4.5 and I need to get alarm events produced by Line Crossing Detection to work with them on my web application.

Which ways do i have to get this information?

I am trying to understand XML from ISAPI method GET /ISAPI/Event/notification/alertStream
but I do not have a clear idea.
What is activePostCount?
How to count Line Crossing Alarms with this method?
Which is what is giving me back this method?
