CONFIGURING THE DVR ON THE LAN
4
Objectives Learn to obtain the information from the LAN
The information obtained will be used to configure your Network device ( DVR, video server, router etc ) properly . Learn simple commands to obtain Network information
5
DISCOVERING YOUR NETWORK
6
1. Network ID 2. Subnet Mask 3. Default Gateway Information Required
Information required from the network: 1. Network ID 2. Subnet Mask 3. Default Gateway
7
Information Required 1. Network ID.
Defines the scope or range of IP addresses available on the network. Obtaining the current IP address from a nearby computer will help to assign the proper information. Determine the available host addresses on the Network. Help us to assign an IP address to the Network Device
8
Network ID Examples **First and last bits are reserved.
Example #1 using Class C IP address Network segment is: Host segment : Available host : 2 – = 254 * N 8 Example #2 using Class B IP address Network segment is Host segment : Available host : 2 -2 = = * N 16 Example #3 using Class A IP address Network segment is Host segment : Available host :2 -2 = = 16,777,214 * **First and last bits are reserved. N 24
9
Information Required 2. Subnet Mask
The subnet mask will determine if the IP address belongs to a single network or it is part of a multiple network
10
Information Required 3. DEFAULT GATEWAY ROUTER WAN IP 24.65.1.130
80 The default gateway IP address will provide a route or map the connection to the Internet through the Router e.g 110 LAN
11
Useful tools
12
DOS Commands 2 commonly used commands are:
The DOS commands are simple and powerful tools that help us obtain information and test your network devices on the LAN 2 commonly used commands are: ipconfig ping
13
DOS Command Window The DOS Command Prompt DOS Command Window
Windows 2000/XP Option #1 Click Start Select Programs /Accessories Select the DOS Command prompt option Option #2 Click on Start Click on Run Type CMD and press OK DOS Command Window
14
Ping Command The ping command helps up to do a simple diagnostic of the network connectivity The ping command sends a packet to the destination host and waits for a reply packet from that host. Results from this echo can help to determine if the host is reachable and present on the network.
15
Ping Command Example RESULTS: Type ping 192.168.1.16 press Enter
RESULTS: Reply from Request time out Host unreachable ICMP. Internet Control Message Protocol
16
ipconfig Command IP address ( PC) Subnet Mask Default Gateway
Helps us to obtain information from the network IP address ( PC) Subnet Mask Default Gateway Type ipconfig press Enter Extended version: Type ipconfig /all press Enter
17
Learning to use and apply the Information obtained from the Network
18
Assigning the Proper IP Address
3 Ways to Assign an IP Address: 1. IT Administrator 2. The Guessing Method 3. The DHCP Method
19
Assigning the Proper IP Address
1. From the IT Administrator On medium to large networks it is recommended to get the IP address from the Network Administrator This is recommended because using the wrong information may cause serious problems on the customer network and unnecessary headaches
20
Assigning the Proper IP Address
2. The Guessing Method Get the IP address from your local PC. Use ipconfig command.. Note : Make sure both units (DVR and PC ) are connected to the same LAN
21
Assigning the proper IP address
3. ADDING A NUMERIC VALUE Example: We have to test and see if someone is using the existing IP address. For example, if the computer IP address is , lets add 5 numbers to the last octet : = 171 Open the DOS prompt and type ipconfig and press enter The resulting IP address will be 4. TEST THE IP ADDRESS Use the ping command to 2. Write on a paper: ( Example) IP address Subnet mask Default gateway If you receive a “reply from” that means somebody is already using this IP address on the network
22
Assigning the proper IP address
5. APPLYING THE SETTINGS Let’s try to use another IP address adding another number to the last octet (lets add 4 numbers, = 175 ) and try again Example: Once we had selected the IP address , we will need to use the same subnet mask and the same default gateway from the computer Perform a ping command to to test if someone else is using the IP address The final values (example) for the DVR will be: IP address 192. 168. 45 175 Subnet mask 255 Default Gateway 192 168 If you get a “request timed out” message, it means that nobody is using the IP address and therefore, you may use it on the DVR.
23
Testing the Network Device
1. Configure the Network Settings on the DVR according with the information from the table. 3. Test if the unit communicates properly on the LAN using the ping command 4 . If you have a “reply from” message your connection is OK. Note : If you have a “request timed out” message, check your settings or physical connections. 2. Connect your Network Device (DVR, video server )to the Network.
24
Assigning the Proper IP Address
3. The DHCP Method . Optional The DHCP server (Router) assigns an IP Address to the Network device ( DVR, Video server etc) automatically. The Network device must support the DCHP feature. General Procedure Access the Setup/network menu on your device (DVR) and select the option to DHCP. Make sure to have your device (DVR) connected to the LAN. Wait a few seconds and check if the IP address refresh on the screen. Once the new IP address was assigned from the DHCP server (Router), write down the IP address on a piece of paper. Go back to the Set/up /Network Menu of the device connected on the LAN and turn off the DHCP mode to Static IP mode and assign the new IP address, subnet mask and Gateway.( if needed). DHCP = Dynamic Host Communication Protocol

CONFIGURING THE DDNS
27
Why DDNS? DDNS-Dynamic DNS Remember a name rather than a IP address
EverFocus Name Service: Dvrname.everfocusddns.com It’s free It’s easy Router port forwarding need to be set still
28
EverFocus DDNS Register from EverFocus Devices Directly
For EDR/EDVR: Set the DVR name and then press SELECT button to submit
29
Check Name Availability
Before register on DVR, check name availability online:
30
View Registered DVR Type the DVR name from browser to go to real machine For example:aaa.everfocusddns.com
31
CONFIGURING THE ROUTER
32
The Router Configuration
The final step to accomplish Remote Viewing access Why the Router is so Important? Allows or deny access to your LAN from the WAN ( Internet). Perform Network communication between your LAN and WAN. The router control remote access using “ports”
33
Common Ports Every IP address is divided into ports.
One IP address can be used by multiple programs to send and receive data at the same time. Examples : - (Port 110 ) Browse the web ( Port 80 ) Port numbers are from 0 to Ports 0 to 1024 are reserved for use by certain privileged services. Application FTP UDP http Telnet ftp VCD VCD VCE DHT VCD VCE
34
PORT FORWARD / DMZ PORT FORWARD DMZ ( demilitarized zone )
Allow users to open single to multiple ports to give access the Network Devices (DVR, Video server) from the Internet (WAN) . The router maps the internal IP address from the LAN to the external IP address using the ports .This process is called Port forwarding Allows to open all the ports at once in the Router for the Network device IP address . Is a nice feature if you are having problems forwarding ports for some application or device. The Network Device with the DMZ enabled is now wide open to internet traffic.
35
THE PORT FORWARDING RULES
WAN IP Ports open? yes 80 Ports to open on the Router for DVR : Ports 2000, 8000, 9000 for IP address 110 ROUTER Local area Network
36
THE PORT FORWARDING RULES
WAN IP Ports open? Example with multiple DVR’s on the same LAN yes 80 Ports to open on the Router for DVR 1 and DVR 2. Port 5410 for IP address Port 5400 for IP address Port 5410 Port 5400 ROUTER LAN
37
How Port Forwarding Works
WAN IP : DVR1 : Port :5400 ROUTER #1 If the user has installed the CLIENT application to view the cameras .The application will try to access the IP address from router #2. ( ) The CLIENT application must have configured the IP address from router #2 address ( ) and the required port “5400” to view the cameras on DVR1 or Port 5410 on DVR2 INTERNET ROUTER #2 DVR 2 : Port :5410 Broadband Modem WAN Broadband Modem Computer IP address Note : If the Client application is web based you have to enter :5410 Local Area Network
38
How to Access the Router Menu
Procedure 1. Obtain the Default Gateway IP address using the ipconfig command from the DOS prompt. 2. Open the Internet Explorer and type in the address bar the Default Gateway IP address -> , press ENTER 3. A LOGIN screen will appear . Enter the user name and password to access the Router menus (if needed). Login Screen
