Assign the DVR MAC address as static IP (DHCP reservation : Chose an IP address for DVR out of DHCP range). Please check router manual or contact network administrator for default gateway IP, login password or how to get MAC masking menu etc. Open DVR menu and note down MAC address of your DVR. Īfter collecting all the information open DVR network menu and the put the details as below. We can get public IP address through any website like. It is basically your internet IP address. To access remotely we need to set primary DNS and secondary DNS too. To access locally just assign IP address, Subnet mask, and default gateway. Multiple DVRs can be connect and accessed through CMS software installed in PC or mobile device. We connect the DVR as shown in the image. Open web browser and type the default gateway IP found through “ipconfig/all”. Check with the Network Administrator if there is single router or multiple in network. The router’s IP address is usually but not necessary the same as the Default Gateway. Open the command prompt (type cmd in search programs) in Windows OS and enter “ ipconfig /all”. OSI model and the 7 layers in terms of Video over IPĬonnect the DVR to the network switch through Ethernet cable. OSI (Open Systems Interconnection) is reference model for how applications can communicate over a network. Virtual ports like 80 for HTTP, allow different applications on the same computer to share network resources simultaneously. We are not talking about physical ports like Ethernet, USB but virtual ports. Network switches and routers used to create WAN. Network switches are used to create LANs.Ī wide-area network (WAN) spans a relatively large geographical area (i.e., any telecommunications network that links across metropolitan, regional, national or international boundaries) and typically consists of two or more local-area networks (LANs). The address is used to establish an IP connection to the same machine or computer being used by the end-user like local host.Ī LAN (local area network) is a group of computers and network devices connected together, usually within the same building. The 127 is the reserved for loopback addresses, such as the 127.0.0.1 address assigned to a PC. IP Addresses are divided into 5 Classes Class UDP (User Datagram Protocol) is a protocol that sends independent packets of data, called datagrams, from one computer to another with no guarantees about arrival. TCP guarantees that data sent from one end of the connection actually gets to the other end and in the same order it was sent. When two applications want to communicate to each other reliably, they establish a connection and send data back and forth over that connection. TCP (Transmission Control Protocol) is a connection-based protocol that provides a reliable flow of data between two computers. MAC address (Media Access Control address ) or physical address, is a unique identifier assigned to network interfaces for communications on the physical network segment. The router is the default gateway for a network. If a TCP/IP computer needs to communicate with a host on another network, it will usually communicate through a device called a router. The subnet mask is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network. The first part of an IP address is used as a network address, the last part as a host address. I am only covering the points used in CCTV networking.Īn IP address is a 32-bit number that uniquely identifies a host (computer or other device, such as a printer, router, DVRs, IP camera etc.) on a TCP/IP network.Īn IP address has two parts. Full explanation of the theory and technology behind IP networks is beyond the scope of this post.
