I got my HFW5231E-Z12E and it is very enthusiastic about storing a series of snapshots to my FTP when motion detection is triggered. I played with the anti-dither setting and looked around for anywhere that I can tell it "dude, ONE photo would be perfect, I don't need four to six of them per event."

The context is it's for LPR, and I want a visual index of the cars, so an extra three to five photos of an empty roadway don't help. Is this configurable and I'm just not looking in the right place?
