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:
Access name for stream 1 ~ 3: 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
H264
and use the following RTSP URL command to request transmission of the streaming data
rtsp://<ip address>:<rtsp port>/<access name for stream 1 to 3>
For example, when the access name for
stream 1
is set to
livesdp
:
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
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 (Real-Time Streaming Protocol) controls the delivery of streaming media. By default, the
port number is set to 554
■ The RTP (Real-time Transport Protocol) is used to deliver video and audio data to the clients. By
default, the RTP port for video is set to 5556 and the RTP port for audio is set to 5558
■ The RTCP (Real-time Transport Control Protocol) allows the Network Camera to transmit the
data by monitoring the Internet traffic volume. By default, the RTCP port for video is set to 5557
and the RTCP port for audio is set to 5559
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:
