D. Bandwidth Estimation
The frame rate of video transmitted from the device depends on connection bandwidth
between client and server, video resolution, codec type, and quality setting of server. Here
is a guideline to help you roughly estimate the bandwidth requirements form your device.
The required bandwidth depends on content of video source. The slow motion video will
produce smaller bit rate generally and fast motion will produce higher bit rate vice versa.
Actual results generated by the device may be varying.

Note: Audio streaming also takes bandwidth around 32kbps. Some xDSL/Cable modem
upload speeds could not even reach up to 128 kbps. Thus, you may not be able to receive
good quality video while also streaming audio on a 128 kbps or lower connection. Even
though the upload speed is more than 128kbps, for optimal video performance, disabling
audio streaming will get better video performance.
E. Configure Port Forwarding Manually
The device can be used with a router. If the device wants to be accessed from the WAN, its
IP address needs to be setup as fixed IP address, also the port forwarding or Virtual Server
function of router needs to be setup. This device supports UPnP traversal function.
Therefore, user could use this feature to configure port forwarding of NAT router first.
However, if user needs to configure port forwarding manually, please follow the steps as
below:
Manually installing the device with a router on your network is an easy 3–step procedure as
following:
