When talking about monitoring wireless internet, they mainly mean:

  • Surveillance via Wi-Fi router;
  • Remote access via wireless (3G, 4G) internet channel.

The first, by the way, is not entirely correct, since in this case we can do without wires only on the camera. server (or recorder) section. If the further signal path runs through a wired connection, then this is described above. Otherwise, we have classic wireless remote access.

When organizing any traffic, the first parameters of interest to us are its volume and the bandwidth of the communication channel. Determining the appropriateness of using a wireless connection is straightforward. This is done in two stages.

Evaluating the flow from surveillance cameras.

Since currently the H.264 codec is used, as a rule, we will focus on it in our calculations. We take the formula:

Rk = RgRvKtsv / 1024/1024 / KSZh. Where:

  • LCD. the size of one frame from our surveillance camera;
  • RG and RV. horizontal and vertical pixel resolution, respectively;
  • CCV. coefficient characterizing the number of transmitted colors;
  • KSZH. frame compression ratio.

As for the colors, for modern color IP cameras we take CV = 24. For monochrome (black and white cameras it will be equal to 2). For the codec mentioned above, the compression ratio is taken to be 75.

The first time we divide by 1024 to convert bits to kilobits, the second division gives the dimension of megabits. Please note. in bytes and translate, since the speed of the Internet, including wireless, is indicated in Mbps.

MultIPly the resulting frame size by the transmission rate (frame / second), we get the value of our stream. By the way, we can immediately take the camera resolution in megapixels, then the formula will be much simpler:

Pk = Resolution in megapixels KCV / CSI.

Thus, the stream of a 1 Mpixel camera at a speed of 25 fps will be: (124/75) 25 = 8 Mbps. Moving on to the most interesting.

3G wireless internet speed.

Maximum, under the most favorable conditions, it will be 3.6 Mbit / s. In reality, it will be 1.5-2 times less. Comparing our stream and the possibilities of a wireless connection via the Internet, we see that we can watch a megapixel picture at a maximum of 6 frames per second.

If you wish, you can calculate other options for wireless GoPro viewing via the Internet and decide how much they suit you. I am not campaigning for or against. numbers are numbers.


It is assumed that if a person is looking for information on how to do something with his own hands, then he does not have sufficient skills in this direction. Surveillance, including remote access via the Internet, is NOT an exception here. For those who independently want to choose, install and remote monitoring, the following sequence of actions can be recommended:

  • Problem Statement. Formation of System Requirements.
  • Choice of equIPment with the ability to access the Internet.
  • Installation and configuration of cameras, recorders, etc.

Despite the seemingly triviality of what has been said, many users ignore the first point, as a result, as a result, they cannot get what they need. Let’s use specific examples to consider how to correctly do it yourself monitoring the Internet on various categories of objects.

Remote access to the Internet monitoring system is implemented most often through IP equIPment. It may have “standard” network functionality or be able to work as part of various services. The second for self-installation and configuration is easier and preferable.

Of greatest interest here are:

  • P2P surveillance;
  • And Cloud Services.

The providers of THESE services have tried to simplify the process of installing the equIPment as much as possible, so organizing Internet monitoring with your own hands in THESE cases will not be a problem. Surveillance of the Internet using P2P technologies uses wireless connections, with “cloud” you can also work by wire.

How To View CCTV Cameras Via The Internet

The use of specialized cameras that support certain services has one drawback. the impossibility of building surveillance with a large number of cameras.

To do this, you should use a wired connection to the Network, and the system will include a recorder or a computer with support for the required number of cameras.

Setting up such remote monitoring can be carried out through the Cloud service or in the order described on this page.


Increasingly, the usual format of offline surveillance is being replaced by Internet surveillance, which allows remote control of the system, camera control, change settings, broadcast data online or view stored archived materials.

To organize observation of this type, the following types of equIPment can be used:

  • Directly IP surveillance cameras;
  • Personal computers, servers;
  • Fixation devices (recorders).

The main requirement for network devices is the ability to identify them. The role of the identifier is played by IP addresses, for the Internet it can be:

  • Static (white). Constant length of the entire operating time of the device,
  • Dynamic. Periodically changing provider.

Some ways to organize monitoring of the Internet channel are discussed below.


Internet monitoring is by definition a remote connection. The only question is how many surveillance cameras we can view at the same time. This is determined by the bandwidth of the communication channel, which consists of:

  • EquIPment capabilities;
  • Your tariff plan;
  • Provider restrictions.

If you are interested in connecting a 4-channel recorder, then for wired Internet, the organization of remote access to such a system will not present any problems. With a large number of surveillance cameras, there may be restrictions on the transmission rate, that is, 25 frames per second may not be seen. Also, you have to sacrifice image resolution.

The method of organizing remote Internet surveillance is determined by the parameters of your IP address.

Internet monitoring with static IP.

Setting up such a connection is NOT difficult. The used device (camera, recorder, computer) in the settings menu is assigned an existing IP address, after which it connects to the Internet. Naturally, for this, our equIPment must have the appropriate software. Hardware capabilities.

After that, we type the desired address in the address bar of the browser (the easiest way) we get access to our surveillance device and its functionality.

But, a static IP address, firstly, costs money, and secondly, the provider may refuse to provide it for a number of reasons. Therefore, the Alternative could be the following option.

Dynamic IP monitoring (DynDNS or DDNS).

Any IP address can be bound to a symbolic link. An example of this can be any site, the domain name of which is converted by the DNS server to the Corresponding address, after which the user gets access to the Needed resource.

Dynamic DNS service is able to track IP changes and bind specific network equIPment to a specific symbolic name.

True, this requires that the surveillance system devices operating via the Internet can track changes in the network address assigned to them and report this to the dynamic service server.

For a personal computer, this is achieved by installing the appropriate program. The client. Other equIPment of the surveillance system (recorders, routers) must have DynDNS support, which should be taken into account when choosing them, if, of course, you plan to work with them via the Internet.

Cloud surveillance service.

In essence, in terms of traffic management, it is similar to a dynamic service, however, it provides a number of additional features both during the installation process and during its operation. (.)


Any IP camera is suitable for organizing Internet monitoring. The only question is how to connect it. “Classic” execution requires the above manIPulations with IP addresses and setting up intermediate devices: router, computer or registrar.

You can, of course, connect it to the Internet directly, but in practice this method is rarely used:

  • First, you need a dedicated line and white IP addresses;
  • Secondly, there is no possibility to create an archive, that is, monitoring will be carried out only in online mode.

Alternatively, there is a way to organize monitoring of the already mentioned Cloud service. But even so, use “naked” the camera is impractical, especially if there are several of them. The direct connection option is possible via wireless Internet, but there are also pitfalls here, which are written at the end of the article.

By the way, some are interested in the use of wireless (Wi-Fi) IP surveillance cameras for THESE purposes. There is nothing special here. The use of Wi-Fi technologies allows wireless signal transmission from the camera to the router. nothing more. Then everything happens according to the standard already described schemes.
