• The traffic of the network and the object of the image affect
the frame rate. The network congestion causes frame rate
slower than the setting.
• When more than one client were viewing, the frame rate
becomes slower.
• Ethernet switching hub can smooth the frame rate especially
in viewing on the Multi-Camera screen.
• Your connection to the Network Camera does not have
enough bandwidth to support a higher frame rate for the
streamed image size. Try reducing the video streaming size
to 176x144 or 320x240 and/or disabling audio.
• Audio will consume 32 to 64 kbps. Disable audio to improve
video. Your Internet connection may not have enough
bandwidth to support streaming audio from the Network

correctly.
• If FTP does not work properly, ask your ISP or network
administrator about the transferring mode of FTP server.

video streaming size.
