Wireless-N Internet Home Monitoring Camera
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.
