3. ZOOM in on the video will enable the detected object to be enlarged. You may see from the FLAME WINDOW above the VASE. The picture at the left is ZOOM OUT, the VASE looks small in the video. The picture at the right is ZOOM IN, the VASE looks larger in the video and the size is much larger than the FLAME WINDOW, which means, the detection could be faster.

(IF the FIRE is smaller than the FLAME WINDOW (ON THE RED SQUARE), the algorithm will not be able to trigger.)
