The main settings of IP DVRs when commissioning ⁠ ⁠

I do not urge you to clearly follow how I will indicate below the typical setting of the IP DVR. But for beginners and for a guideline, in order to “not forget” something to configure something, it will definitely go. This description refers to the input of the IP DVR IP.

Consider by the example of setting IP DVR RVI.

Your DVR is already connected to the network and you know its IP address. The IP address of the DVR can be configured by connecting it to the monitor and using the mouse go into the network settings and there you can already see it or register it you need. After on the computer, start the Internet Explorer browser (yes, it is for this browser that all manufacturers drag their software) and write the IP address of the DVR. A request for the installation of a plugin for a browser will appear, install and log it in the DVR control panel.

First of all, go to the settings (“set”) and connect the IP camera to the DVR.

Next, you set up the quality of the recording of video surveillance cameras. Compression use codec h.264 or higher. Bitrate. Vbr, I already wrote about it. The rest is adjusted individually depending on the current task.

If necessary, “call” each camera 🙂 For example, the first camera can be called. Yard.

If you plan to use P2P (remote connection to a video recorder from the phone), then turn on. I have already written about my attitude to P2P. Solution How to configure remote access without p2p. And if you have a public static IP address, then you are here.

There are usually these settings by default, but be sure to check.

Be sure to set up time in the DVR. This is a very important point when watching videos.

Change the administrator password. If necessary, create additional accounts.

If the DVR is connected to the monitor or TV, then set up a comfortable resolution and, if necessary, turn off the assistant.

Set the automatic reboot.

Next, you set up the type of recording constantly or by movement. Perhaps from the basic settings everything. I will be glad to answer your questions. Perhaps someone will share their experience in the basic settings. Good luck!

Connection of the RVI DVR to the Internet using P2P.All RVI registrars support the P2P function, with the exception of the MA series, also the version of the chip 2.616 and above.one. First of all, you need to connect the DVR to the 3G router, with a configured Internet connection, or directly connect the Ethernet cable from the provider to the network port of the registrar and configure PPPOE. If your provider does not support PPPOE, then the connection is performed through the router. When connecting using a router, do not forget to turn on the DHCP on the registrar2. Next, you need to enable the P2P3 function in the DVR. After you turned on the P2P you need to restart the DVR DVR no longer requires settings4.

How to connect a DVR to the Internet via router

First, let’s look at a few points.

one. Which DVR can be connected to the Internet?

Anyone with the port “Ethernet”, and there are now the vast majority.

Thus, you should not think that you can only connect to the network of video surveillance registrar. What is also called analogue (DVR with support for AHD, TVI, CVI formats) is also suitable, subject to the specified condition.

  • Creating a video of the archive on the user side (HDD DVR);
  • Remote access to the cameras AHD, TVI, CVI (that is, not IP);
  • the ability to use free tariffs “Clouds” while connecting several video cameras.

He is a “intermediary” between the registrar and the Internet. Almost any model is suitable, including so that you already use at home to work on a computer.

The main condition is the presence of a free LAN port. In its absence, it will be necessary to acquire an uncontrollable switch (sweatshirt) as an extensor.

During the wired connection, it is enough to connect the port “Ethernet” of the DVR with a free lan porter.

For those who have not encountered this, I can recommend material about how IP video surveillance works.

After we connected the DVR to the router, we can move on to the organization of remote access to it. We mean that the router is connected to the Internet.

connect, video, recorder, phone, monitor, connection

By the way, this can be a wired connection, which is typical for most apartments, and using 4G connection.

In the latter case, you need a router with a built.in 4G modem or the ability to connect such a modem via USB.

How to connect a DVR to the phone via the Internet

As already mentioned, the easiest way is to use a cloud video surveillance service.

You should know that specific models of registrars can work not with all cloud services, but usually with one, less often two. The description (instructions) indicates the “clouds” supported by him.

I would recommend the first option, since the tariffs of various providers of cloud services differ much more than the for recorders supporting one or another service.

In order not to repeat, I will give a link to the material about the organization of video surveillance through the phone. All the organizational technical points are described in detail there in detail.

After that, it remains to install an application of the selected cloud service on the smartphone and register our registrar there.

Since in this case the connected DVR is a network device, the procedure is no different from those that are performed when connecting via IP video surveillance chambers via the IP phone.

In addition, there is a video. In any case, just consider that instead of the camera you have a registrar. All actions are carried out one in one.

A few more quite common questions.

How to connect a DVR of a particular brand to the Internet (Hiwatch, RVI, Hikvision, Dahua, etc.)?

There is practically no difference, the only thing that by default they will have different logins and passwords. IP default addresses may also vary, but these are all trifles.

connect, video, recorder, phone, monitor, connection

How to connect a DVR to the Internet via Wi-Fi?

Firstly, there are registrars with a built-in Wi-Fi module, but their proposal is limited.

Secondly, if so impatient (although in most cases there is no sense in Wi-Fi connection), then you can use the Wi-Fi access point.

Any DVR is connected to it by wires (patch cord through the port “Ethernet”). And she is already connected to the Wi-Fi to the router.

There is no separate text material on this topic yet, sorry.

Network setting RVI camera 1nce2120

Download the configtool utility. Using this utility, we will produce all network settings. Network settings can be done not only through configtool. If all the devices are in one subnet, then you can enter the address of the camera 192 through the browser.168.one.108. Serve the power to the camera-open the browser and see the entrance to the Web-Inteatheis of the camera. First you need to log in. Default login Admin.

When first connecting to the Web-intese, a system message will appear with a proposal for the installation of the Activex component. Click OK and the operating system will automatically install the components.

So, the first inclusion of the camera, provided that we are in the same subnet. We introduce 192 to the browser.168.one.108

Choose a region and language, then create a password for entering the Web camera settings and enter an email to restore password.

Setting through Configtool

It is necessary to specify (search settings) subnet in which the camera will be searched. Since only 255 addresses are possible on the network 192.168.1, then indicate from 0 to 255. Click OK and find the camera.

On the right there are green buttons with which you can: change the IP address, details-view the IP address and version of the software with the serial number of the camera and enter the Web-Inteatheis. The camera will open by default in the IE browser.

Choose the camera. Next, we will go into the settings change IP address and set the checkplace in DHCP. Unless of course you need to set a static IP address. Since the router has already seen this camera at the address, then by DHCP he issued the same address 192.168.one.108. If we connected the camera to another router, from another subnet, then the address will change.

Now we go to the Web-Inte Web. There we install the password and email. Then it is proposed to enable P2P service. P2P allows you to connect the camera to the DMSS application to watch a live video. About it a little later.

Open the Web-Inte Web camera via Configtool or simply enter the camera address. In my case it is 192.168.one.108. We also enter a new password there.

To watch a live video, you need to install the Activex component. Just click on the link and all automatically be installed. In Web.the intese is made all the main camera settings. The Camera Data, such as serial number for remote connection to the camera, is indicated in the system.

We set up remote access to the DVR using 3 or 4 G connection

Often business owners or just wanting to see what is going on in the country set video cameras and a DVR. However, such a solution has a little inconvenience. the DVR is installed locally, but I would like to see what is happening on the observed object from any place. The Internet comes to help.

I must say right away that the task of setting a remote video surveillance may be at a standstill if you are faced with this for the first time. Many DVRs say that they support 3 or 4G, as if hinting that you can use mobile Internet for remote access. This is what newcomers come across.

Often your modem simply will not understand the DVR. This is a very good argument. In addition, mobile operators give these modems a gray IP address or simply redirect to their gateway or block ports. Even if you were given a dynamic IP (I remind you that the gray IP addresses start from the range 10., or 172 or 192, the rest are all white, but dynamic), then after a break in the connection to your device will be assigned a new IP, which negates the previous settings. Sometimes this is solved by using DDNS (dynamic DNS), where you can contact the device according to the symbolic name, and not by constantly changing IP. There were many such services before, but almost all of them became paid. Only No-IP remained.com, but he will be useless in this situation. So that DDNS knows that the IP on the device has changed, he needs to inform him of this. All DVRs that I saw do not know how to do this.

In this case, you still will have to install a router and raise DDNS on it and configure port testing. If you still want to use a 3G/4G connection, then there will not be so many options for connecting to it. this is a static, cloud, VPN (paid and quite expensive) or specialized services like this

However, do not forget that wired Internet is also used to connect. While the No-IP service.COM allows you to configure remote video surveillance, and it will be free. The theme of the NO-IP setting is not included in this article and I will miss it (you can see on the No-IP website).

In addition, there is always an “iron” solution in the direct and figurative meaning of this word. Some models of modern routers support the built.in DDNS, the address which receives guaranteed from its cloud. In this case, access by the remotion to the router and the registrar will be quite simple and you will not have to pay for it. Nevertheless, there are restrictions, here you need to go deeply to the issue, studying both the documentation of such a router and what is required of remote access.

Attention! Next, we will build on the fact that statics or white IP address for DDNS are used. If this is not, it is better to read the Комментарии и мнения владельцев after this block.

However, back to the topic of our article. Often they still want to access the DVR of 3 or 4 G connection. For a 100% guarantee of the implementation of the plan, it is worth buying a 4G router (I recommend using ZYXEL Kinetic as the most convenient solution). DDNS Dyndns and No-IP services are already built in its firmware. The first became paid and is useless to us, the second is completely free. We register on this service and create a free host, according to which we will try to reach our DVR. After receiving Login, password and host name, they will need to be entered into your router, restart it and already try to penetrate it. If the ping goes on this host, I am postponing, the static IP is no longer needed. You will simply drive into the browser the name of the registered host and the number of the open port, which you throw. If the ping did not go, then you need a static IP.

Having received a static IP, you will need to configure the router to pass the ports.

I will make a reservation right away. the instructions given will be relevant and if the DDNS service worked for you. Therefore, be careful.

So, let’s say we have Yota operator and we use his modem. Well, the settings in ZYXEL will be very simple. In the settings of the rules of broadcasting addresses (menu security broadcasting network addresses (NAT)), pour TCP port 80 (used by default) to access the web configurator of the Internet center.

If we turn to the icicom that the operator gave us, we will get to the Zyxel Kinetic web Mord. Please note that in case of access to the DVR, it is necessary that it be physically connected to the router. Then it will be necessary to indicate the IP of the registrar in the field in the field “redirect”.

That’s it, now you can drive your iciciter into the video recorder into the browser.

In general, this topic is very extensive. I gave the most stereotypical example. There are many options. However, if you need help, write. How I can, I will help.

Small adjustment of the article from 19.02.2017

Despite the fact that the article already has a respectable age. almost four years, nevertheless, judging by the issues that they are addressed to me, you still need to supplement it.

Please note that you can come to the registrar or cameras in just a few ways:

  • Having a public static address. Everything is simple as I described in the article. However, the difficulty is that it costs crazy money and therefore does not always fit.
  • DDNS services. These include such services such as No-IP.com. But there is also a feature here. These services allow you to enter the remote resource by the domain name. But only if there is access to them. In other words, these services will work only when you can already go to the registrar remotely. There are simply public static and dynamic addresses. The piece of iron was rebooted, and you were given a new address that you do not know. In this case, DDNS helps just. In the case of cellular operators, you are always given gray dynamic addresses. No need to look at what is written by 2IP services, showing the address on the Internet. This is the address for NAT. The TCP/IP protocol itself implies the fact that at least one address should be public. As a result, mobile operators create a pool of gray addresses on their modems, which by means of NAT go to the Internet. In other words, these are ordinary local networks. Theoretically, there is a chance that having two identical modems of the same operator, you can get to the remote registrar as a local device inside the network. But this is a very big luck. And since these are non.public addresses, DDNS will not help here, you can not even waste time setting them up.
  • Will save VPN in this situation. But they are paid. I did not describe their work and configuration, since VPN access providers have extensive wiki pages. But this method will access 100%. Links in the article are stupid, since you can find more or less optimal on the Internet. You need to keep in mind one thing. the demand for VPN will always be high and the will not always be adequate. But you can look for.
  • P2P or cloud. All the same to the gray address. But the quality of the cloud leaves much to be desired. But there is a freebie.
  • Progress does not stand still and services appear to connect remotely to any device by 3G/4G connection with the gray address. For example, this service is notable for the fact that it stands very cheap (compared to VPN that have lined up, although you can rummage there). But the benefit of working with him is still outweighing all other options.

Connection of the phone to Hikvision DVR

Steps for access to Hikvision DVR from a mobile phone are very simple. Install the IVMS-4500 application on a mobile phone, press the Hik-Connect button to create an account, and finally add DVR, pointing it on its mobile chamber of its QR code.

The step.by.step process of setting up the Hikvision DVR for viewing via the Internet:

  • Install the application on a mobile phone. Now that there is basic information about the IP address DVR and ports, you can download a program for remote access to DVR.
  • Open the Play Store on Android or App Store on iOS to download and install the Hikvision IVMS-4500 application.
  • Create an account by clicking in the next window “Register Hik-Connect”.
  • Enter email address and press the “Get Code of Confirmation” button
  • Check mail, enter the code, “further” and create a password.
  • Add DVR to the IVMS-4500 app.
  • Open IVMS-4500 and press the button
  • The program opens a camera for scanning a QR code that is located in DVR.
  • In the next window, request a code located on DVR.
  • After its input, the application shows the connected device, thus setting up the Hikvision DVR to view via the Internet completed.

Setting a video surveillance system

The idea is to initially connect the cables from the digital DVR to the router and work in a local configuration for testing, and then in a remote network under the usual control mode.

If the user already has access to the DVR from the Internet using a mobile application, and the local and remote configuration in test mode demonstrated normal performance, but something still does not work properly in normal mode, the following steps can be performed.

DVR. Local connection and configuration:

  • Connect the DVR with the CAT5E network cable to the router.
  • Connect the router to the Internet provider. When setting a router, the DVR pay attention to the router. It usually has blue ports that are used for internal devices, and a yellow port for connecting to the Internet.
  • Check a local DVR connection.
  • Before setting up the remote mode, they are convinced that there is access to a digital DVR using a computer or laptop with web browsers: Internet Explorer, Google Chrome or Firefox.
  • Most digital DVR and IP cameras are compatible with Internet Explorer (IE), so it is recommended to first try this web browser, and then others.
  • In it (IE), the IP address DVR, as well as the name of the user and the password, which are created.
  • Usually, when the user for the first time tries to access DVR through a web browser, a message appears with a request to install a plugin. Just press to accept the offer, and unpack it.
  • After entering the correct name of the user and password, you can see your cameras through the web browser, which means that the local installation is in order.
  • DVR works correctly through a local network and sends a video to a web browser (IE).
  • It is convinced that DVR has all the correct information about the network to configure remote access, which can be checked in its menu.
  • Press on the DVR “Configuration” and “Network” menu.
  • The main settings menu of the network are checked by the following: IP-address IPV4 DVR, depending on its range, the IPV4 subnet mask usually coincides with the mask of the computer, the IPV4 default gateway. This is the IP address of the router, DNS server. You can use 4.2.2.2 and 8.eight.eight.eight.
  • If the DHCP flag is installed. The protocol of the dynamic configuration of the host, the digital DVR will receive all the information from the router, they simply make sure that it is true and remove the DHCP flag.
  • Set up DVR ports, the program uses them to communicate with a web browser, computer software and mobile application. These are virtual ports, not physical. Information is available in the “Network” menu in the “Basic Settings and Port” section.
