Note: This function requires an API license.
This command returns a list of specific events for specific cameras. The parameter startid is required to return a list of events. If omitted, or startid is zero or negative, an empty list will be returned with the lastEventId value. The lastEventId value can be used to query for new events.
All other arguments are optional and can be used to filter the kind of event. Filters are and-ed together, meaning the event must match all filters. The argument types is a comma separated list of types (strings) the event must match All events that match one of the types supplied are returned (after ending together with the other filters). If this parameter is omitted, all event types are returned.
The results are always sorted in ascending time. Because of the internal working of the system, it could happen that the order of eventid’s differs from the order of eventtime’s. For example, the result list, ordered by eventtime, could have an eventid sequence of 1, 2, 3, 5, 4, 6.
The result will also give the last event id back. To get only the last event id, issue this command with a zero or negative start id.
Every event in the eventlist has several result fields. Refer to the Event result fields table for a list of all result fields. The value of all event result fields depends on the software version and setup.
The list can be limited by supplying starttime, endtime and/or limit. Refer to chapter
Result list. for an explanation of these parameters.
The parameters deviceid and serverid can be used to get events from a specific device (from a specific server).
