To make sure the heat map function operates properly
• The human/car classification function performs at an optimal level when the camera installation angle is set
between 30 and 60 degrees.
• It is recommended to install a camera at the height where the full aspects of recorded objects can be seen.
If you set the camera location to <Outdoor> then the car/person classification function will operate. If you set it to
`
M
<Indoor>, the heat map cannot display detection results for cars.
