I've got a custom setup with my C100's - A server listens to their RTSP streams and records the data to disk. This works fine.

However, I also want to listen to the notifications that the camera sends out when motion is detected.

To do this, I need to know what data is being sent, and how I can subscribe to it, or intercept it.

Is it TCP or UDP? Can I subscribe, listen, or poll? Or is this all done through the tp-link servers?

If needed, I can use wireshark to intercept the data, but it's a lot less trouble to get the answers here.
