Is there any API that I can mark same flag on record? For example, I want to know the record include some alarm.

Please elaborate, I do not understand what you would like to do.

I’m so sorry about this. I would like to mark some flag on record video so that I can search the video by the flag. For example,I need to record a time from 12:00 to 13:00 that trigger a record video. Ehen I can search by my record to know which time trigger a record video?

There are so many ways..

  • If you trigger an event then the event could trigger a rule so that you know for a fact that something has been recorded. Events can be searched for.
  • You could use bookmarks to flag the time that you have an interesting recording that you want to be able to find again.
  • You might say that if there is recording then it is interesting, then the task would be to search for periods with recorded video, SequenceDataSource would be an excellent tool.
  • Alarms denotes what is interesting, alarms can be found.

If you want to explain your idea further please describe what a user would see and would do.
