Image_processing from jpeg camera feed?

Ok the issue I have is I have a JPEG camera and when I go to its feed (the camera http://…cgi) and refresh the page there is ALWAYS a new image based on the feed… but home assistant seems to “refresh” its copy of the image every 30 seconds or so …
I want to use image_processing on the said image and I have its scan_interval set to 1 seconds … the issue is that I get 30 scans on the same image since HA’s feed is only updating every 30 seconds …

How can I force the update interval to be less, as right now this is useless for person detection as they can simply walk through the zones undetected?!

Thanks,
Kris
