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.
