Section 3 - Configuration
NOTE:
Microsoft® Internet Explorer does not support server push technology; therefore,
using http://<ip address>:<http port>/<access name for stream 1 ~ 4> will fail to
access the Network Camera.
RTSP Streaming
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.
Access name for stream 1 ~ 4: 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 and use the following RTSP URL command to request transmission
of the streaming data.
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.
