The general principle of organizing access to an IP camera via the Internet. Connecting the PC to the domain How to access your home folder and other network resources

IP camera- These are devices that combine a video camera and a mini-computer. The features of the IP camera include the transmission of a video stream in digital format via Ethernet networks(Wi-Fi), which uses the TCP/IP protocol. Ethernet is a packet technology for transmitting local network data. The device receives an IP address on the network through which you can access the web interface, through which the camera is configured and where the image from the camera is displayed. But sitting at home or in the office and observing what is happening within the premises is not as interesting as if you organize access to an IP camera via the Internet, i.e. from any place on Earth with Internet access, see what is happening at home or in the office. How to set up access to an IP camera via the Internet That's what this article is about.

In order to gain access to your IP video camera from an external global network Internet) you must have a unique name (unique IP address) on the global network. First, let me clarify what IP addresses there are:

White IP- a unique address on the global network. Public "white" addresses are used on the Internet. A public IP address is the IP address that is used to access the Internet. A device with a public IP address can be accessed from anywhere on the global network, because public (global) IP addresses are routed across the Internet, unlike private (grey) IP addresses.

Gray IP- this is the internal IP of the local network, directly accessible only within this network.

Private gray addresses include IP addresses from the following subnets:
From 10.0.0.0 to 10.255.255.255 with mask 255.0.0.0.0 (class A network)
From 172.16.0.0 to 172.31.0.0 with mask 255.255.0.0 (class B network)
From 192.168.0.0 to 192.168.255.255 with mask 255.255.255.0 (class C network)

Static IP- this is a fixed address on the Internet;

Dynamic IP- an address that changes over time.

Providers generally provide either a dynamic gray IP address or a dynamic white IP (much less often). You can determine the address if you connect the provider’s cable directly to your computer/laptop using online services:

http://2ip.ru
http://smart-ip.net
http://speed-tester.info/ip_location.php
http://hideme.ru/ip

Or go to the router’s web interface and see what IP address you received from your provider. If you use a dynamic gray IP address, you need to contact your provider and order a “white” IP address service from them. If you are using a dynamic white IP, you need to go into the IP camera settings and see which DDNS services (the DynamicDNS service allows you to match Domain name with a dynamic IP address of a network device.) is supported by your video camera (if it is supported at all). After this, you need to go to the service website to register account DDNS by specifying a unique domain name. Then enter this name in the IP camera settings in the DDNS settings. After a certain time, the video camera will check your IP address and update the ddns record (please note that the update does not occur at the same time, there may be a delay due to caching of the address by your provider or you).

Setting up an Internet connection in the IP camera itself.

First, let's look at the easiest way to access the camera via the Internet. Modern IP video cameras can do without a router, i.e. can be directly connected network cable provider to the camera, configure the Internet via the web interface and voila. After this, you enter http:// (your white IP address) in the address bar, for example http://95.110.64.7 and connect to your IP camera.

This method has a significant drawback - the use of only one IP camera.

Setting up connections via the Internet for several IP cameras.

If you want to use several IP cameras, in addition to a “white” IP address or configured DDNS functions and several IP video cameras, you will also need a router. So, the principle is as follows - having configured the Internet on the router, connect all IP video cameras to the router, no matter in what way using an Ethernet cable or wireless Wi-Fi networks. After that, go to the web interface of the cameras and change the connection port, instead of 80, change it to any value from 1000 to 65000. In this case, the ports should be different on different cameras, for example, for camera 1 - port 1000, camera 2 - port 1001, camera 3 - port 1003. Next save the settings on all IP cameras. The next step is to forward the ports on the router, to do this, go to the router’s web interface, find the “Port Forwarding” item or similar and specify the camera port and its IP address and save the settings, more details about port forwarding are written in the article Port forwarding on routers Asus, D-Link, TP-Link, Zyxel . If you did everything correctly, enter the address http:// (your white IP address): (video camera port) in the address bar of your browser, for example http://95.110.64.7:1000. This way, you can connect to your IP camera1 from anywhere with Internet access.

In addition to a computer and laptop, you can connect to the IP camera using a tablet and smartphone. To do this, you can use the browser installed in the gadget or install the application from the store: for Android devices from the store Play Store, for Apple devices with Apple Store. Launch the store and in the search bar enter the IP camera manufacturer and the word camera, for example “D-link camera” or “TP-Link camera”. In the list of applications, select the application, install it, enter the settings, usually it is enough to indicate the connection name, IP address, port and login and password for the connection.

In order to connect your new device to the network, you need to follow several steps.

1. Make sure your Computer or Router is set to auto mode obtaining an IP address.
2. If you are already our subscriber, and you have already connected some devices to our network, then contact technical support with a request to disconnect all devices from your account. If you are a new subscriber, then skip point 2.
3. Open any browser (Opera, Chrome, Mazila, Explorer...), enter the address of any site in the address bar field. The system will automatically redirect you to the user account.

Be careful, because from this moment the system can open two versions of the page: one normal, without the error Fig. 1, and the second with the error Fig. 2.

In the second case, you will need to restart your browser (just close and open it again), because... The lease time for the temporary address has expired.

In the first case, you need to enter the login and password that you were given upon connection, or when signing the contract.

4. After entering your login and password, a window for registering the device in the system will open. Here you just need to click the “Registration” button, see Fig. 3.

5. After this, the system will display a message about successful registration, see Fig. 4.

6. The system informs you that registration has been successfully completed. After this, you need to restart all your devices (Router, Computer...).

7. If you accidentally double-clicked the “Registration” button, then you will receive a system message in response, as in Fig.5. The system simply informs you once again that your devices need to be rebooted.

On computers included in the domain of the mathematical and physical faculties of VSPU (FIZMAT domain), you can use your username and password to log into the system. This will allow you to create your own settings appearance and behavior of programs, store personal files, and use network resources, including the home folder on the server. Your settings will not affect the settings of other users, personal documents will be available only to you, and you can access them from any computer in the educational building.

Note.
In some cases, your home folder may contain other sections. Currently it is possible to have the following folders:

Archive
This is a folder in which you can store files that are large enough that you don't need to access them frequently and that aren't of critical value to you. This folder, like private, is accessible only to you.

How to access your home folder and other network resources

Whenever you log on to a computer with your credentials, the following network drives are mapped to the computer for your session:

Z:
This is your home folder. Contains folders private, public And shared(see above), as well as a link to this document.

X:
This is a network folder that combines various local network resources (network folders for the server and classrooms).

The most important of them are:

Homes
Home folder directory. Here you can find your home folder, as well as the folders of other FIZMAT users. If you want to transfer some files to some FIZMAT user, then use this resource by copying the files to Public in the home folder of the corresponding user.

Tutorial
This folder contains educational materials on various subjects that you can use in class or for homework.

Media
This folder contains collections of drawings, presentations, sound files, and electronic textbooks that can be used in the classroom. If you would like to add to these collections, please contact technical support.

Public
This is a link to \\server\public . This folder is intended for temporary storage of files and information exchange for unregistered FIZMAT users.

Attention! Safeguarding your data in a folder Public not guaranteed. The folder is limited in size and is subject to periodic cleaning.

If you have a need to create additional folders or links to existing resources, then contact the service technical support FizMat. For example, teachers can link to their folders Shared For quick access students to the teaching materials laid out for classes.

Where is the best place to save your data?

If only you should have access to the saved data, then save it in Private your home folder, or in the folder "My Documents" the computer on which you work under your account. These folders keep your data safe, but each option has pros and cons:

Accessible from any computer on the local network

Data is stored on a server protected from technical failures

− The volume of your files on the server is limited

Not registered on the network - how to fix the error: so, you have your own new one Samsung Galaxy S7 or any of the other androids and suddenly you find the Not registered on the network error. Message "Not registered on the network" usually appears when trying to make a call. The easiest way to solve this problem is to manually add a network operator. Take a look at this guide to see what you need to do.

Error correction Not registered on the network

1. Go to Settings
2. Find Wireless Networks
3. Go to More – Mobile Network
4. Click Telecom Operators

The device will search for all available networks in your area. From the list of found networks you will need to select your mobile operator. Ready.

If the phoneSamsung Galaxy S3, 4 or 5 says Not registered on the network, what should I do?

Yes, any, even these flagship smartphones, like Samsung Galaxy S3, 4 or 5 are also affected by this error. Usually the message Not registered on the network appears when you want to make a call or write a text message to someone, and suddenly this error pops up. What to do then? Why does this error occur?

In order to make a call or write an SMS, your mobile operator must receive your phone number, when this is impossible to do, then a window pops up with the message Not registered on the network or the subscriber is not registered on the network.

Why does this happen? This is probably not important, but for information - sometimes when updating the Android operating system, the numbers and letters in the IMEI change to SN 0000. Sometimes this happens when replacing a SIM card, the phone cannot find the network and needs your help.

Offline mode

First way, which can easily help is to turn on and off airplane mode on your phone. Each of you knows how to do this. What happens? When you turn on airplane mode, the radio on your phone turns off and it stops receiving a signal. After you turn off the flight mode, the radio transmitter will again search for the operator’s network signal. If this method does not help and the phone again says Not registered on the network, go to method number 2.

SIM card

Second way, also very simple, is to remove the SIM card from the phone. Before removing, turn off the phone so that the firmware does not accidentally leak; do not immediately insert the SIM card back, you need to wait a little, literally a couple of minutes. So, we took our phone, turned it off, took off the cover, took out the SIM card, waited a couple of minutes, inserted the SIM card, put the cover back in place, and turned on the phone. We are trying to call. If the error Not registered online no longer appears, then hurray, we succeeded! Well, if not, don’t rush to get upset. Let's move on to method number 3.

Checking the functionality of the SIM card

Third way provides for this possibility when the cause of the error Not registered on the network is not the phone, but a faulty SIM card. What to do in this case? Let's check the functionality of your SIM card on another device. If she doesn't work there either, then contact your mobile operator to replace the SIM card. If the SIM card in another phone works fine, then you should use method number 4.

Firmware is to blame

In the fourth method, we recommend updating the firmware. First, check to see if an update has arrived over the air on your phone itself and you haven’t noticed. If there are no updates, then you will have to reflash your phone yourself.

Do you want to connect your computer to a local network, but don't know how to connect it to a domain? This is very easy to do, and you can use different methods.

The question of connecting a computer to a domain usually arises among system administrators who need to create a local network. A domain system means that all computers on the network use the settings of the main PC. Let's try to figure out how to connect a computer with an operating system to a domain Windows system 7. For other OS, the connection is not too different.

What are the benefits of a domain structure? With it you can use, for example, group policies and centralized management. This allows for efficient work.

Important Requirements

Before you enter a Windows 7 computer into the domain, you need to check whether the PC meets a number of requirements and whether all settings have been completed. There are quite a few of them, although most of them should already be produced. Check the following:

• The following versions of Windows 7 must be used: Professional, Ultimate or Enterprise. Only these versions can be joined to a domain;
• Must be present LAN card. But this goes without saying;
• A local network connection must be made. In most cases, although you can connect Windows 7 to Windows Server 2008 R2 in offline mode, but that's a separate topic;
• The correct IP address must be specified. It can be configured manually, obtained from a DHCP server, or it can be an APIPA-address (its values ​​start with 169.254.X.Z);
• You need to make sure that the controllers (at least one) are available for connection;
• Also check the controller connection (for example, you can ping it, that is, check the quality of the connection);
• The DNS server must be configured correctly. This is important; if it is not configured correctly, problems may arise when connecting to the domain. Even if the connection is successful, failures are possible later;
• DNS servers must be available. To do this, you need to check the connection using the PING program;
• Check your local permissions. You must have local computer administrator rights;
• You need to know the domain name, administrator name and password.

Connecting a PC to a domain

There are two ways to add a computer to a domain. Let's look at them in more detail.

First method

This standard way connecting a PC to a domain. Follow these steps:

• Click the “Start” icon, right-click on the “Computer” shortcut, select “Properties”;
• In the “Computer name, domain and work settings” item, click “change settings”;
• Open the “Computer name” tab and click “Change”;
• In the "Part of (something)" section, select "Domain";
• Enter the name of the domain to which you are connecting, click “OK”;
• Enter your name and password again.

Then restart your computer. After this, the PC will be connected to the domain on the local network.

Second method

You must use the NETDOM application. To connect a domain, command line you only need to enter one command:

[[("type":"media","view_mode":"media_original","fid":"334","attributes":("alt":"","class":"media-image"" height":"123","typeof":"foaf:Image","width":"938"))]]

Wherein:

• The parameters “DOMAIN.COM” and “DOMAIN” must be replaced with the domain name. You also need to specify your login and password;
• The extra "d" in "user" and "password" is not a typo;
• In Windows 7 NETDOM is already included in the operating system. IN Windows versions 2000, XP and 2003 need to install Support Tools.

To complete the connection, restart your PC.

What to do if the domain has “dropped out”?

This happens after the PC is connected to the domain. The computer simply doesn’t “see” it. You will notice this immediately, because you will not be able to log in. Do the following:

• Log in as a local administrator;
• Go to system properties and in the “Computer name” section, note that the PC is part of a workgroup;
• Restart your computer;
• Then reconnect the PC to the domain as described above;
• Reboot.

The computer should now join the domain.

Placing a computer in a specific container

The disadvantage of the described methods of connecting to a domain is that the PC is placed in a standard container, usually in the “Computer” folder. And to move to another location, an administrator is needed. But you can place the computer immediately in the right container. There are two options for this.

Method number 1

To do this, first create an empty account where the computer is located (you need to have rights to create an object). In the ADUC console, a new account is created with the same name that will be used to connect to the domain. Then use the connection method described above. The system will see an account that already exists in the domain, but is simply not mapped to it. After matching, the computer will fit into the desired container.

Method number 2

You can use the Powershell command:

• Log in with administrator rights;
• In the command line, enter “powershell” (then you can use PoSh instead);
• The command to include a PC in the corp.company.ru domain from under the corp\company_admin account, creating an account in the corp.company.ru/ Admin /Computers container, where company is the name of the computer, will look like this: add-computer -DomainName corp .company.ru -credential corp\ company_admin –OUPath “OU=Computers,OU=Admin,dc=corp,dc=company,DC=ru”;
• A new window will open in which enter the company_admin user password;
• Then the “WARNING: The changes will take effect after you restart the computer pcwin8” window will appear (pcwin8 means operating system). Restart your computer.

Now the PC will be located in the desired container, where the domain refers.

To correctly connect a PC to a domain, it is better for the administrator who created this local network to do it. He knows about all the pitfalls in this domain, and therefore can quickly connect. If you decide to connect your computer to the domain yourself, then in case of any problem, leave the PC in this state until a specialist makes a correction.
