to ensure the clear visibility of facial features. 
3.  Select indoor environments with calm air and consistent temperature condition. 
Outdoor environments with rapid temperature changes are not recommended.   
4.  If this scheme is used in entrance scenes that connect indoors and outdoors 
environments, It is suggested that the installation location should be kept at a 
certain distance from the entrance (such as customs or security checkpoints).   
5.  Avoid objects with high or low temperature placed in the scene. 
6.  The devices should be installed firmly, thereby avoiding face detection and 
temperature measurement errors caused by shaking. 
7.  Skin-surface temperature can be affected by environment temperature, if it’s too 
hot and cold in outdoor environment, we recommend people to stay indoor for 
more than 3 minutes before temperature measurement.   
2)  Camera Installation 
  The camera should be set right in front of the one-direction path, capturing the 
full faces of passing persons. The installation height and the distance between 
the camera and measured objects is depended on the resolution and focal 
length of thermographic camera, as shown in the following table.   
  There are tripods, tripod adapters, wall mount offered by HIKVISION for flexible 
or fixed placement, but these items require additional purchase. Only device 
with resolution of 384*288 is recommended to be installed on the wall.
