6.1.1 Connecting to Internet
Two common connection methods are shown below
1. Connecting via switch or router
2. To connect directly through network cable, the IP address of the computer should
be changed so that it is on the same network segment as the camera
e.g.: The factory-preset default IP address of camera is 192.168.100.100. The
computer IP address must be set with the same network segment, such as
192.168.100.101, so that the computer can be connected correctly with the camera
Change network settings

format, while resolutions of 1080P and below are encoded in either H.264 or MJPEG
format (the media player will choose automatically). However, some media players or

32
conference meeting apps may not display images when using 4K resolution due to
conflicts between the A71P H.264 format and the software itself. In that case, please
lower the resolution to 1080P.
To utilize the USB camera source, launch a media player like PotPlayer or a conference
meeting app such as Zoom, then select the camera source.
