 Try to reduce the scene complexity as much as condition allowed; it is not recommended
to use Intelligence Behavior Analysis in scenes with intensive targets, changing lighting
conditions or small difference between target temperature and scene temperature.
 Try to avoid the following scenes: scenes with reflective surfaces such as glass, bright
ground or water; scenes that disturbed by tree branches, shadows or winged insects;
scenes that against light or under direct light exposure. Control image proportion of objects
that are with high relative ambient temperature.
