4. The object distancedepends on the focal-length of the lens mounted in the camera. 
5. In order to guarantee the captured face recognition rate, the requirement for face capture are: left or right face turn angle is less 
than about 30°; pitching angle is less than 20°. 
6. Face illumination must be uniform, if the brightness is low or there is a large area of shadow, need to do the light filling. 
7. When the capture scenario is backlight, the camera’s BLC/HLC/WDR need to be turned on, or fill the light. 
8. The face recognition do not support black & white mode for now. 
4.5 Network Configuration 
4.5.1 TCP/IP 
Go to NetworkTCP/IP interface as shown below. There are two ways for network connection. 
Use IP address (take IPv4 for example)-obtain a local IP address automatically through DHCP. A typical router has a DHCP server 
built in, and therefore is able to assign an IP address to the camera. 
Use PPPoE-Click the “PPPoEConfig” tab to go to the interface as shown below. Enable PPPoE and then enter the user name and 
password from your ISP.
