Hey there, @Pete-hd. Your observations are correct, and you are certainly doing this right. Optimising motion is best done through trial and error, as each environment varies. Activating the zones for detection and adjusting sensitivity separately presents the opportunity to adjust each individual option depending on the reaction of your current configuration. Keep in mind the sensitivity applies to your motion detection as a whole, rather than per zone. That being said, I can also very much understand your desire to visually confirm how sensitivity impacts your motion zones.
