Remind me on a Dahua NVR, where you go to set the # seconds it should pre-record for a camera's IVS rule?
For example, if my IVS rule is triggered, I want the camera to record the 15 seconds BEFORE the event happened as well, so in my DMSS app I can easily see what led up to the IVS event trigger...
(hopefully that make sense -- I assumed this is on the NVR, not the individual cameras)
