Is there such a RTSP Ping?
===

I am currently working on a WinForm app to stream videos from IP camera using the RTSP protocol in C#. Everything worked fine. Part of the requirement for the app includes a function to check whether the IP camera is online or not. 

So I did a ping function using the System.Net.NetworkInformation.Ping class to ping the IP camera. Say if the RTSP url of the camera is as follows rtsp://**[CAMERA IP]**:554/Master0-RTSP/1.0, I would only need to extract the **[CAMERA IP]** part and use the Ping class to see if the camera is online or not by using its IP.

Initially, it works until an issue came, say if one to enter an IP which may not be the intended IP Camera (say an IP of a computer) the ping function would still work if the entered IP of the entered device is online.

I tried to search for something like a RTSP ping but could not find one. Was hoping for any advices or opinions on this matter. Any example in C# are greatly appreciated. Thank you for your kind attention.
