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.
