Port
Base Port
The network base port is used for communication between systems. In order for the servers and
remote systems to be connected together, the port number must be identically set.
HTTP Port
HTTP port use for web-based connection.
RTSP Port
Enter the RTSP port is used for RTSP-based connection. The default RTSP port is 554.
RTSP (Real Time Streaming Protocol) is a standard for connected client(s) to control
streaming data over the World Wide Web.
Authentication
RTSP Authentication
If RTSP Authentication is set on the network page, the user should enter the correct user ID
and password when any RTSP client is connected.
HTTP API Authentication
When HTTP API authentication set to ON, HTTP Authentication is asked for all clients which
use HTTP API .
RTP Session
RTP (Real-Time Transport Protocol) is an Internet protocol used for transmitting single real-
time multimedia data such as audio and video to a select group of connected clients. Normally
RTSP uses RTP to format packets of multimedia content. The RTP Session menu is used when
the RTP is streaming without an RTSP connection. The RTP stream will be transmitted to
the destination set. The SDP (Session Description Protocol) file can be found in the server, and
a client can retrieve it using an http connection.
Domain Name System (DNS) is a database system that translates a computer's fully
qualified domain name into an IP address. Networked computers use IP addresses to
locate and connect to each other, but IP addresses can be difficult for people to
remember. For example, on the web, it's much easier to remember the domain name
www.amazon.com than it is to remember its corresponding IP address (207.171.166.48).
Each organization that maintains a computer network will have at least one server
handling DNS queries. That server, called a name server, will hold a list of all the IP
addresses within its network, plus a cache of IP addresses for recently accessed
computers outside the network.
