1 FPS - not logging despite positive detection


I have a Cloud API system setup that is receiving a feed from a camera at 1 FPS.
It is running on an Intel Core2 Duo L9300 which is quite a slow CPU but it is detecting the license plates at 100% of the frames. The problem is that it often is taking a long time to log that license plate despite the fact that the visual display shows a green outline and the correct license plate. Is there a setting I can change so that it logs the license plate quicker?

The system is fine at 1 FPS as it is for car parks, we will be running several of them with this CPU if it is fine.
