CGI Commands

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.
