Read the blue question marks in the configuration to understand more.Here it is tracking... Notice it is RED and has a frame count?Here is is NOT tracking. Notice it is not red and the detected frame count is 0That value will increase for every frame that is detected. Once it reaches the specified frame count, the Tracking Start script will execute.There are tons of blue question marks and information about tracking within the camera control configuration. Even right beside the Start Tracking script edit button is a blue question mark. The drop down to select the number of detected frames is also on the same page as the Start Tracking script.
