I have a logic to down load a video on an event. The start time of the event is set to 5 seconds prior to the occurrence of the event and duration to 15 seconds. So I am attempting to download the video after a delay of 20 seconds of receiving the event notification in my service.But i receive a file with zero bytes. To get successful download, i had to wait for 2 minutes before calling the direct download api. Is this a limitation or I can do something to correct?

  Hi @...,

  I assume you want to download events that occurred while the recording is still in RAM (~last minute before live). 

  This limits you from the immediate download.

  So once the video is available on the disk, it would be available for download. Is my understanding correct.

  In that case can i be assured that the delay between live video and the one stored on hard disk is 1 minute. Or is it dependent on the hardware?

  Hi @...

  You can not be assured for all systems that it is one minute since it depends on hardware and the number of processes within Nx Witness (logging, rules, etc). More than 1 minute is rare though.

  Thank you! Norman. I will later verify on arm based hardware and confirm.
