Find recording from nvr within specific time

[Puneet94100]

we are using Dahua NVR and we stream live cameras through it. As Dahua stores the recordings in somewhere we want to access the past recordings (of specific time). The code I mentioned gives the whole saved recording of NVR. But as I said I want specific time's recording. I have provided the filter for that as well but it seems to be not working probably. Please guide.

scope = {"Scope" : {"RecordingInformationFilter": filter },
"KeepAliveTime":"PT60S"}

source_token = record_search.FindRecordings(scope)
get_result = record_search.GetRecordingSearchResults(source_token)
