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.

from onvif2 import ONVIFCamera, ONVIFService

nvr_ip = "192.167.11.155"
nvr_username = "user"
nvr_password = "passwd"

nvr = ONVIFCamera(nvr_ip, 80, nvr_username, nvr_password,wsdl_dir= "/home/itsupport/Desktop/vms_1/python_onvif2_zeep_master/wsdl" )

media_service = nvr.create_media_service()
record_search = nvr.create_search_service()
replay = nvr.create_replay_service()

filter= "boolean(//Track[TrackType = 'Video']),2023-08-20T08:07:43.000Z,2023-08-22T08:07:43.000Z,1,10,1"
scope = {"Scope" : {"RecordingInformationFilter": filter },
"KeepAliveTime":"PT60S"}

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