Video Performance Information
The video quality is dependent on the video parameter settings and the
network quality. If you want to have a better video quality, you will usually set
higher resolution and higher frame rate. This is fine when you are viewing the
video locally in the same network. But when you want to see the video
remotely through the Internet, you need to know the Internet speed (bandwidth)
connected to your home network. If the “Internet speed” setting of your IP
camera is very large, but your real Internet speed (bandwidth) is relatively low,
the video quality could be very bad. In some worst case, the video display
could be disconnected. In order to have the best video quality, you better have
broadband service from your ISP and set the “Internet speed” of the IP camera
a little lower than the real Internet speed provided by your ISP.
To notice that when multiple users are displaying the videos from the same IP
camera at the same time, the video bandwidth times number of users will be
needed for the Internet speed.
