How to change the signal from an IP camera. Connecting an IP camera via a router. Cloud video surveillance - connecting a digital IP video camera via the NOVIcloud cloud service.

The devices use the web protocol to transmit video and are usually used as surveillance and control systems. Any computer connected to the network can access the IP video cameras registered in it. And if there are no particular problems with choosing a device today, then not everyone can figure out how to connect it.

Some models also allow planning, so motion detection is not always active. Then you need to configure what happens when motion is detected. For example, send a signal to an alarm system, which then triggers an alarm. To do this, you specify one or more recipient addresses. For example, with three images or a short video clip to the receiver.

My network camera is not working, what should I do?

If you have a domain with webspace or server, you should know something about it. The network camera registers with the server as you do it yourself, for example, upload multiple pictures. The network may be congested. If possible, reduce the resolution and image quality to maintain a fluid video image. Add cameras to compatibility mode. . If your DVR or network recorder does not recognize your hard drive, the following options are available.

Connection features.

Let's start with the fact that connecting an IP camera can be done via a wired connection or wireless technologies. Everything directly depends on the specific model of the device, connectors and interfaces of the equipment to which the connection will be made, and on the wishes of the user himself. You should decide in advance how the camera will be connected in order to purchase the necessary equipment.

Format your hard drive. . However, the network camera cannot cache a large video file before downloading. This is also possible with the security cameras just mentioned. We explain how the system works here. Since the network camera does not transmit analog video signals only video signal, but much more, it can no longer be equated with this technique.

The camera is now part of your network. It all depends on what kind of system you get. Additionally, there are many other features that vary from manufacturer to manufacturer. In addition, you can make the camera available to multiple users in different places. This is not possible with analog video technology. The intuitive setup also provides beginners with the knowledge of how to configure the router to get quick results.

If we talk about wired connections, today in most cases twisted pair is used. When installing analog models, you can resort to coaxial cables, but in this case the connection distance will be limited to 300 meters. In addition, this type of cable has a limited number of conductors, which was enough for analog, but not enough for digital.

Below is a simple configuration with the following components. The network camera home page displays live video from the camera along with links to display camera configuration, Image Settings, Network and Email. This guide consists of two parts. The first part describes the background of port forwarding and the use of port numbers.

Checking the operation of the CCTV camera

The following picture shows how the router is connected to your home network via the Internet. Also look at how the router connects as a "switch" between your home network and the Internet. This is the number that makes the device visible to other devices on the network. This allows the router to communicate with all other devices that are connected via the Internet.

Therefore the choice falls on twisted pair. So, which one is suitable? Today, the following types of cables are used in network video surveillance systems:

The most common due to its low cost and ease of installation. Distinctive feature– absence of shielding shell. One of the significant disadvantages is low resistance to interference. Therefore, when installing them, you should avoid placing them close to electrical wires and other sources of interference.

Connecting the WiFi camera to the Internet

To establish a connection, you need to redirect the home network where your network camera is located. As long as you are connected to the Internet, you can communicate with your router through your home network. You must tell the router which device you are connecting to. You can implement this using port forwarding.

Connecting an analog camera to a PC

Computers, phones, and other devices on a network use different and sometimes multiple ports to connect. Ports are used to differentiate between these various types communications. Currently, port 80 is mainly needed for communication. This port is used by default to access the website. The network camera has its own web server software that creates its own website with the camera image and settings.

It differs from the type of twisted pair presented above by the use of a foil sheath that protects against interference. If you have to connect IP cameras in places with strong interference, then an FTP cable is preferable.

It can be called the most protected. A copper braided sheath is used. In addition, each conductor is shielded with foil, which protects against powerful interference. In addition, most manufacturers make a fire-resistant PVC outer shell.

Of course, you can set your network camera to a different port, for example the default port for this connection is port 80. Now you can connect to devices externally using the port number. If you want to access multiple network cameras, you need to assign a port number to each camera.

Connection without a router

However, this does not know which device should be available on the network. The setting you should do on your router is port forwarding. Three steps must be completed. Set the camera to a different port number. Set up port forwarding in your router.

Based on user reviews, we can say with confidence that optimal solution will become a UTP cable. Unlike others, it does not require grounding, is significantly cheaper (even coaxial), and is easy to install.

It is best to lay wires for connecting cameras while finishing the room, so that later you don’t have to look for a way to “hide” the cable.

Setting up port forwarding in your router

If you have multiple cameras, each camera must have its own port number. Click "send" to save your settings. The camera will restart. When this is done, only the installed port number can be reached to the camera. Unfortunately, routers different manufacturers Dont Have standard descriptions router settings. Therefore, the port forwarding configuration on each router may be different.

You must log into your router. Other popular addresses. In most cases, you will be prompted to enter a username and password. You can also find out what you need to enter in your router's manual. Sometimes the data is also marked at the bottom of the router.

Twisted pair can be classified:

By area of ​​application.


The UTP cable for connecting the video camera must have crimped RJ-45 connectors on both sides. You can do this yourself using a special tool (pliers) or buy a ready-made connector.

Once you log in, you will be taken to the router settings website. Here you need to find the menu item where port forwarding is set. The following options are possible. "External Port": Enter the camera port number here. For other types of routers, you can find out where the port forwarding is on your router via the Internet.

When you get a picture of your network camera, everything worked! If steps 1 and 2 went correctly, the other settings are quite simple. If the settings are correct, an image of the connected network camera will appear. On the way, check that everything is in order. It's easy with webcams that cover your eyes when you're not at home. And you can even see yourself from the other side of the world. There is a match for every requirement.

The advantages of connecting via twisted pair include the ability to create an entire system of cameras on one line using a switch. Of course, the IP camera needs power; it can be organized in several ways.

Firstly, you can simply lay an additional cable, which will provide energy. The method seems simple, but requires additional costs for work and materials. Secondly, you can resort to installation in close proximity to cameras and power supplies. Finally, providing power via loose conductors in a twisted pair cable. However, this method is only suitable for devices that support PoE (Power of Ethernet) technology.

A simple webcam for 20 euros is usually sufficient for simple tasks monitoring. In principle two are available different solutions. On the one hand, there are computer cameras. The computer remains turned on and the webcam software sends images via e-mail owner or transmits the video to the Internet.

Find the right CCTV camera

Only a power cable is required if the camera cannot run on battery power. The camera is then connected directly to the camera so it can send live images. If a fixed area needs to be monitored in an interior that is always well lit, a simple camera with a hard viewing angle is sufficient. If the camera needs to be able to monitor large rooms or areas with different angles review, it is best to use a rotating and turning camera. Such cameras can often even be controlled via the Internet.

In addition, there is an option that allows you to transfer information signal and supply voltage along the same conductors.

With a wireless connection everything is much simpler. The main requirement for IP cameras and other equipment is support for WiFi connections. This method saves the user from installing wires, replacing them in case of damage and other related problems. However, this is not without its drawbacks either.

Connecting to a DVR

Or they automatically adjust the range of presets over and over again. These cameras are available in stores from approximately 180 euros. Cheap cameras only produce 640 by 480 pixels, which in itself is quite common, but will ultimately disqualify the cheapest one, basically with poor quality Images. This type of moving camera is best mounted under the ceiling so that it can cover all corners and areas of the room. If rooms are not lit at night, a camera with night vision is recommended.

If, on the other hand, the camera needs to monitor an external area that is not lit at night, the camera must have a weatherproof housing and be equipped for night photography. The camera's Night Vision mode provides bright, clear images in the dark thanks to infrared illumination. Suitable external cameras are available from approximately 250 euros. More advanced cameras are also equipped with a heated housing, so that the camera does not become foggy in spring and autumn, and in winter the cold disk does not bother you.

Wireless cameras are more expensive. Additionally, the WiFi network may be unstable, resulting in frequent connection dropouts. When connecting in this way, you should take into account the presence of walls, access to the network of other users, and other factors.

CONNECTING AN IP CAMERA VIA A ROUTER

So, let's start with what a router is. Although, everyone modern man familiar with this useful device. It is often called a router, switch or switch. It is a device for accessing a worldwide or local network to a number of computers and other devices simultaneously.

Camera software provides motion detection

Even electronics can be damaged in extreme cold. Most webcams can continually update images or even provide a constant video stream on the Internet. But no one can or can spend hours on the Internet looking at a live image to see if something untoward will happen. Therefore, modern webcam software provides various features that make monitoring easier. This includes motion detection.

When motion is detected, a reference image of empty space is first stored. As soon as something moves, the software recognizes it as a deviation from the reference image and records the corresponding images. If nothing moves, the camera doesn't record. Good software will even allow you to monitor only a specific area. The user marks the desired area in the reference image. In this way, zones can be blown out in which the required movements occur.

Its main task is to transfer data packets from the provider to the user. Today there are two types: wired and wireless (can be combined).

The router can become a device to which a number of IP cameras, as well as user computers, will be connected. The connection method (wireless or wired) depends on the camera and router. Wired requires a UTP twisted pair (straight) with an RJ-45 connector at the ends. The first end goes into the corresponding connector of the router, the second end into the camera.

UniFi Video app

In most cases, the software can also send emails with recorded images to let the owner know that something has happened in the monitored area. In addition, some programs also send images directly to the smartphone.

Public CCTV display

Video monitoring: An information sign is often required. The legal side cannot be ignored. If the surveillance also includes a public space, such as a citizen test or the street in front of your home, public staircases, or other areas that are considered public, then you should point out the video surveillance.

Don't forget about powering the device, which can be provided by a power supply or PoE technology. The user's computer is connected to the router via a network cable, after which the IP camera is configured.

For the first wireless connection of an IP camera to a router, you will need a UTP cable. It is necessary to enable WiFi on the device via a computer. You need to enter a special panel to configure the camera’s operation in wireless networks, where you must specify the user’s WiFi password. After this, it will be connected to the network, and the cable can be disconnected.

In this case, you must attach a clearly visible sign that informs you that there is constant video surveillance in the area. Additionally, you should also ask your neighbors to get permission if the camera only needs to capture part of your neighboring property. Network video surveillance is the future of video surveillance technology. Network cameras are a powerful and, above all, simple way to implement video surveillance for your own four walls. Their easy installation makes network cameras extremely user-friendly and easy to upgrade.

The switch allows you to connect several devices simultaneously, the image from which will be transmitted to one or more computers. To do this, you will need a model with a set of LAN ports (if a wired connection is made). In addition, the user will have to assign each camera an IP address obtained from the provider.

The same goes for wireless connections. Because modern cameras presented a large number models, detailed instructions should be found in the package or on the manufacturer's website.

Connecting through a router has many advantages, but there are also disadvantages. The first is that the distance to connect devices is often limited to 100 meters. If exceeded, problems may occur with the quality of the transmitted image, as well as with power supply. In this case, intermediate switches will be required.

A wireless connection, which has a certain range established by a specific router model, is not ideal in all respects. In addition, minor obstacles can seriously reduce this radius.

CONNECTING THE IP CAMERA TO A COMPUTER

Often, one IP camera is enough for a user to, for example, provide surveillance small room. In this case, you can avoid spending on purchasing a switch by connecting the device directly to a personal computer. The principle is similar to other connection methods.

To connect an IP camera directly (directly) to a computer, a UTP cross cable is used, and not a straight cable, as is the case with a router. The difference is that the cross view is used to connect devices of the same type.

The first attempt to access the camera interface may be unsuccessful - the computer is on a different subnet. Therefore, it is necessary to find out the IP addresses local network computer (in the Network and Sharing Center) and camera (in the attached documentation).

Then you need to change the camera's IP address to the one the PC uses. This is done using the software included with the device. After this, the image from it will be available to the user at the specified IP address.

Connect directly to network card computer allows you to save on buying a router or recorder. However, this method makes it possible to connect a single camera. To create a network of several devices, you will have to purchase additional equipment in any case.

CONNECTING THE IP CAMERA TO THE RECORDER

Recorders are special devices that organize the operation of IP cameras, digitizing material and recording it on removable media. Any modern video recorder can work with a personal computer as part of a local network or be used autonomously.

Recorders are equipped with various additional features, for example, recording only if there is movement in the frame (motion detection). As a rule, accompanied software, which makes it possible to control the device remotely.

The standard operating mode involves recording around the clock. Modern models are different high speed traffic. They can be connected to monitors on which images are displayed in real time. In addition, the video will be shown from several cameras at once. You can also study already filmed material.

IP cameras are connected to switches, which, in turn, are connected to the LAN port on the recorder. In this case, the cameras receive power from their own adapters. Many modern models are equipped with PoE ports, which allows you to connect cameras directly, providing them with energy.

This method eliminates the need to buy a router, but there is a caveat. Please note that one camera occupies one PoE port. That is, you can connect a certain number of devices comparable to the number of ports.

There are also IP video recorders with built-in switches. In this case, each camera is connected via a separate communication line, which is not always convenient.

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 over an Ethernet network (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 access your IP video camera from an external network (from the global 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 what DDNS services (the DynamicDNS service allows you to map a domain name to the dynamic IP address of a network device.) your video camera supports (if at all). After this, you need to go to the service’s website to register a DDNS account and specify 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 disadvantage - use 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 differ by 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 Play Store, for Apple devices from the Apple Store. Launch the store and enter the IP camera manufacturer and the word camera in the search bar, 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.
