Network Configuration
Dahua IP cameras feature a built-in Web interface to control all aspects of camera operation.
This section includes details about the supported network protocols, configuring IP addresses,
and configuring alarms and local recording options. Refer to the camera’s
Operations Manual
for full details.
Network Protocols
Dahua cameras support RTSP, RTP/TCP, RTP/UDP, HTTP, DHCP, TFTP, QoS, IP version 4
(IPv4) and IP version 6 (IPv6).
RTSP – Cameras communicate with video management systems over Real Time
Streaming Protocol. Do not change the RTSP port unless you are sure your VMS does
not use the default setting.
RTP/TCP – The Real-time Protocol/Transmission Control Protocol is best suited for
applications that require high reliability, and transmission time is relatively less critical.
RTP/UDP – The Real-time Protocol/User Datagram Protocol is used for live unicast video,
especially when it is important to always have an up-to-date video stream, even if some
images are dropped.
HTTP – The Hypertext Transfer Protocol is an application protocol for distributed,
collaborative, hypermedia information systems.
DHCP – The Dynamic Host Configuration Protocol allows network administrators to
centrally manage and automate the assignment of IP addresses. DHCP should only be
enabled if using dynamic IP address notification, or if the DHCP can update a DNS server.
TFTP – The Trivial File Transfer Protocol is a simple, lock-step, File Transfer Protocol
which allows a client to get from or put a file onto a remote host. TFTP lacks security and
most of the advanced features offered by more robust file transfer protocols such as File
Transfer Protocol.
QoS – Quality of Service guarantees a certain level of a specified resource to selected
traffic on a network. A QoS-aware network prioritizes network traffic and provides a
greater network reliability by controlling the amount of bandwidth an application may use.
IPv4 – The IPv4 (IP version 4) is enabled by default and obtains the IP address
automatically. The address can be used to allow or block network traffic that matches a
specified address or protocol. The IP address must be valid for the network. For more
information, contact your network administrator.
IPv6 – A typical IPv6 (IP version 6) node address consists of a prefix and an interface
identifier (total 128 bits). The prefix is the part of the address where the bits have fixed
values or are the bits that define a subnet. A typical IPv6 address may resemble the
following example: 2001:db8: :52:1:1. The IP address must be valid for the network.
Before making changes to the IPv6 address, consult with your network administrator.
