I did get the Key to go to 1.0 as I found the interval setting. Thanks.Are you changing the iframes in the camera? FPS and iframes and two different things. By default, it will double the FPS for iframes unless you manually change it. So if you change FPS from 15 to 22, the iframes will adjust automatically to double and thus the KEY of 0.5 unless you manually force them to match.
Which Amcrest model is it? Many here (including myself) have an Amcrest camera that we can set the FPS and iframes in the Amcrest camera to match. Maybe you have some obscure one that doesn't allow you to manually set iframe rates
Now to figure out Why this cam is performing the same as the REOLINKS
