Authentication: Depending on your network security requirements, the Network Camera provides three
types of security settings for streaming via RTSP protocol: disable, basic, and digest.
If basic authentication is selected, the password is sent in plain text format, but there can be potential risks of it being intercepted. If digest authentication is selected, user credentials are encrypted using MD5 algorithm, thus providing better protection against unauthorized access.
The availability of the RTSP streaming for the three authentication modes is listed in the following table:
| Quick Time player | Real Player |
Disable | O | O |
Basic | O | O |
Digest | O | X |
Access name for stream 1 ~ 5: This Network camera supports multiple streams simultaneously. The access name is used to differentiate the streaming source.
If you want to use an RTSP player to access the Network Camera, you have to set the video mode to H.264 /
rtsp://<ip address>:<rtsp port>/<access name for stream1 ~ 5> For example, when the access name for stream 1 is set to live.sdp:
1.Launch an RTSP player.
2.Choose File > Open URL. A URL dialog box will pop up.
3.Type the above URL command in the text box. 
rtsp://192.168.5.151:554/live.sdp
4.The live video will be displayed in your player as shown below.

RTSP port /RTP port for video, audio/ RTCP port for video, audio
■RTSP
■The RTP
■The RTCP
The ports can be changed to values between 1025 and 65535. The RTP port must be an even number and the RTCP port is the RTP port number plus one, and thus is always an odd number. When the RTP port changes, the RTCP port will change accordingly.
If the RTP ports are incorrectly assigned, the following warning message will be displayed:
