5 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.

5.1 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.
