Switching TCP/UDP Transmission Mode You can select the communication port of the video/ audio data as TCP or UDP. This function can be used when the Video mode (page 36) is set to MPEG4 and the ActiveX viewer is used. Notes fire-wall is installed between the camera and the computer, or depending on the network environment, the video/audio may not play properly when UDP (Unicast) is selected. In this case, select TCP. UDP (Multicast): This is selectable when the multicast streaming (page 36) is On. When UDP (Multicast) is selected as the transmission port, RTP (Real-time Transport Protocol) and UDP multicast techniques are adopted for video/audio transmission. By selecting it, the network transmission load of the camera can be reduced. If a router which does not correspond to the multicast or the fire-wall is installed between the camera and the computer, the video/audio may not play properly. In this case, select TCP or UDP (Unicast). • The function may not operate correctly when you use personal firewall software or antivirus software on your computer.

In an environment capable of reading Web page, you can watch or listen to the video/audio by selecting TCP port. UDP (Unicast): When UDP (Unicast) is selected as the communication port, RTP (Real-time Transport Protocol) is adopted for video/audio communication. As RTP is the protocol for running video/audio data, video/audio can be played smoother than when TCP (HTTP) is selected. If the Switching TCP/UDP Transmission Mode 29
