30 Wireless-N Internet Home Monitoring Camera
Appendix D
If the client player is the QuickTime player, the latency is always approximately 3 second. If there is no audio
content in the streaming, you can use the extension parameter “[?|&]latency=no” to push the QuickTime
player to play the streaming video without any latency, but this method causes the frame rate to be unstable.
Example: rtsp://<ip>/img/video.sav?latency=no
Note that the camera is able to support the following four RTP protocols, but the user needs to specify the
desired RTP protocol in the player.
• Unicast RTP
• Multicast RTP
• RTP over RTSP (RTP over TCP)
• RTP over RTSP over HTTP (HTTP tunnel)
Return: Video and/or audio is returned.
