rtsp://<address>:<port>/Streaming/Channels/<id>/
rtsp://<username>:<password>@<address>:<port>/Streaming/Channels/<id>/
Where <address> is the IP address of your camera, <port> is the RTSP port of the camera, and <username> and <password> refer to the login credentials of your camera.
Using the first format, you will be asked to login and verify your credentials before being allowed to view the stream.
Using the second format, you will automatically login when requesting the stream
<id> refers to the channel number and stream type of the camera. For example, an <id> of 101 refers to channel #1 (first digit, 1xx) using the main stream (second and third digits, x01).
Typically, you'll use a program such as VLC Media Player to decode the RTSP stream.

http://<username>:<password>@<address>:<httpport>/Streaming/Channels/1/picture
Where <username> and <password> are the login credentials of the camera in question, and <address> and <httpport> are the IP address of the camera and its HTTP port (default 80).
The above URL will present a snapshot of the camera's current live view. Typically, this is used to embed a regular snapshot based on a time interval on a web page, but there are of course many things you can do with the URL.
