Optimise Distance between Camera and Detection Area
For SPOTBOT to detect a human figure, the general rule of thumb is that the human figure must be greater than 15% of the height (vertical size) of the video frame sent to SPOTBOT. Please refer to the picture below. Also, try to avoid situations where human figures exceed the height (vertical size) of the video frame.
Therefore, ensure that your camera is installed at an optimal distance from the area that you want SPOTBOT to monitor.
