Object Travels x Pixels?

Post by RoadHazard » Mon Aug 05, 2019 11:10 pm

I assume the trigger option "trigger only when object travels __ pixels" really means just what it says: that the object must travel x pixels in the X or Y direction before it will trigger. For example, setting this option to 200 on a camera with 2048x1536 resolution means the object must travel approximately 10% of the horizontal distance across the frame?

Or do "pixels" mean something different in the context of this option?

Here is a good YouTube video on Blue Iris: Triggers - Object Detection that should answer your question.

This YouTuber has many excellent Blue Iris video tutorials mostly based on Blue Iris 4 but should still be applicable to Blue Iris 5.

Handy, thanks.

My takeaway is that "pixels" really does mean the camera's pixels, not some special Blue Iris definition. It also has nothing to do with the low-res/high-res setting in Blue Iris. To higher the resolution of your camera, the more leeway you have to define the "object travels x pixels" setting.
