The safety of property and the safety of the home have been of interest to man since ancient times. Powerful doors and tricky locks, and later wireless surveillance cameras for the home, are designed to prevent intruders from entering private property.
A modern surveillance camera with a Wi-Fi network interface can not only perform the recording function everything that happens in the protected area, but also transfer footage CCTV online over the internet in the country.
The owner can conduct video surveillance of the house via the Internet around the clock, just by laying powered by a 220V socket to the camera and connect the device to the router.
WiFi Wireless Video Camera for Home easy to install and works with almost any router. Sometimes, however, there may be software incompatibility with the router, but this is only possible if the device distributing the Internet is released by a manufacturer that is not very well known on the market.
Wireless camcorder usually for home has the following features:
Equipment can transmit video high definition.
The owner will be able to see everything that happens in his house from anywhere in the world.
For this you need any device connected to the internet, camera IP address and password.
Special software allows set up broadcasting and carry out recording and video surveillance over the Internet for giving online. Included to many cameras go even motion sensors, which can inform the owner about the intrusion into the house of uninvited guests and even send their photos.
The camera has its own own IP address, built-in web interface And alarm module. It can function wherever there is an internet connection.
Wifi surveillance camera for home provides great opportunities. Firstly, you can place the camera by choosing the most advantageous place with the highest viewing level. More no need to run wires and be limited to the possibility of summing them up, because you no longer need to connect to a server or registrar.
Wireless video surveillance system for home has and other benefits:
The wireless Wi-Fi camera is considered one of the best on the market, and its competitor is .
Even such an advanced method as remote video surveillance in the country with online video viewing has its drawbacks. This is about signal quality.
WiFi zone limited by distance, so on large objects you need to use antennas. This shortcoming applies to a greater extent to vast territories and affects little apartments and small houses.
The signal is being transmitted using radio waves microwave range. Signals are transmitted in the middle frequency range. The range of the wireless signal we need has its own international classification: WLAN.
A camera that provides wireless video surveillance for a summer residence needs to be set to the highest possible height, its location should provide the best overview.
Every device has blind area”, these features must be taken into account during installation.

An excellent option would be for video surveillance wi-fi for home with 3G router. This is a simple kit, but it is quite effective. The camera will not only record video surveillance for the home via the Internet in the visibility zone, but also send a message in case of intrusion.
Step-by-step instruction how to make video surveillance in the country via the Internet:
Important! The password must be complex. You can even use random number generator and generate a password, or at least part of it.
Take some random numbers, letters, and something memorable for you and remember the password. Or write it down and save somewhere in a secluded place.
IP camera needed to plug to the switch, and it to the computer. After that change network address in which the surveillance device is operating. For this you need to go to the network and sharing center.
The item we need is LAN connection.
Press the button " Intelligence and look at default gateway.
Need to change it to the IP address of the camera, which we received using the program that comes with the kit.
To use wireless video surveillance for a private home, you need in the web interface camera connect it to work via WI-Fi. Choose in settings your network, enter the password and save.
Determining how a network will work in a particular location is not a trivial task. For this tests needed who will evaluate the solution you have chosen.
A huge number of factors influence the network: antenna type, number of connected clients, various obstructions. Also note that the camera transmits data at a rate from 128 Kbps to 3-4 Mbps, and this is a very serious load on the access point.
Router manufacturers write on the box maximum load, which the device can withstand, but these figures are always too high, and we accuracy matters. Use special programs that show all connected subscribers and the transfer rate of their data and signal.
However, 20 Mbps is enough for one camera. This is a decent speed for home Internet and acceptable for the camera. A smaller channel will result in poorer picture quality and transmission delays.
To amplify the signal, you should use an antenna and adjust it horizontally and vertically.
Before installing the antenna, be sure check its frequency range. With a weak, bad signal, you can turn the antenna towards the camera.
To ensure reliable protection of information that is transmitted, many different methods are used. Can be used encryption, firewall and passwords.
Firewall gives access to the system registered to users, but not authorized - completely refuses access.
Passwords give access to systems observations, and the encryption of the information protocol prevents attackers from viewing the video stream.
Now many organizations use wi-fi video surveillance systems. After all, the considered method allows, if desired, to view the video stream even at some distance. What's more, the WiFi-enabled camera eliminates the need for a dedicated wired system, greatly reducing installation costs.
The central source directly involved in the operation of a video surveillance camera is the Internet. However, for wireless operation, you need to connect a special router so that you can perceive the video signal from a distance and send it to the monitor.
This router is directly connected to the cameras. You can monitor what is happening from anywhere, not only using a computer, but also a mobile phone. The main thing is that the components of the wireless network are configured for an Internet connection.
How does a w-ifi security camera work? The principle of operation of a Wi-Fi camera is to transfer an image to an ip video server online. In this case, you can record on additional media related to computer technology. If you plan to install one video camera, then a router or access point is not needed.
To date, there are several schemes that allow you to establish the work of wireless video surveillance. The most popular is the connection of wi-fi cameras with a network video recorder through an access point.
Sometimes, after installing CCTV cameras, problems arise with their operation. Therefore, before starting the installation, you should understand the general structure of the wi-fi camera.
So, the device in question consists of a processor, matrix, board, connectors. This collection is usually called a module. The device works properly only if the light is correctly focused on the matrix. To accomplish this task, the wi-fi camera must be equipped with a lens.
Camera board in the case
A set of components for collecting wi-fi cameras
According to the method of mounting lenses, the following types of connections are distinguished:
The main difference between these compounds is the amount of light passing through the camera lens. If you visit a specialized goods market, you will notice a large number of modifications of the C / CS type.
The first step is to adjust the focus of the video camera system by changing the distance from the matrix to the lens. It is necessary to rotate the regulating part on the body gradually, loosening the fixing screw. Although some camera models do not require adjustment, since the lens is initially fixed at the set point.
In the modern world of telecommunications, the image from CCTV cameras can be observed while in another city if routers are installed in the system in question.
By configuring routers, you can achieve good picture quality. So, each home network video camera should have access to a virtual server. Thus, it is necessary to dial a specific router address and a specific forwarding port. The system requires the above procedures in cases where monitoring is carried out with multiple cameras.
The principle of operation of wi-fi surveillance cameras through a router
Module configuration. In the set of the equipment in question, users are usually provided with a program for Wi-Fi surveillance cameras. With its help, you can correctly configure the IP address of the module and the local network. Images are viewed through the LAN and the global Internet. But such a process is carried out only if one of the two types of IP addresses is available for the camera as a monitoring device. When this is not possible, users resort to DDNS technology. Then automatic updating of the information that is on the server is provided, and the access to the video surveillance camera occurs through the domain address.
Modern models of the devices in question are suitable for connecting thanks to a patch cord if they support P2P technology. The setting here is done by entering the device ID and the password of the program itself, which is included in the package from the manufacturer. Additional actions to improve the image in this case will not be needed.
If the installation of wireless video surveillance is planned for the first time, then the whole process may seem quite simple.
Consideration should be given to the location and methods of installation of the equipment. These two factors affect further setup and image transmission quality. After all, the principle of operation of the security system can be changed, depending on the type of module used.
So, there may be street surveillance cameras on the objects. They work like a well-coordinated mechanism, since the router, camera and modem are in the same housing. In this case, it will be enough to put the necessary SIM card, which will automatically configure all the necessary functions, as well as connect the camera to the Internet. Naturally, these systems are very convenient to use in places where it is difficult to establish access to the Internet.
Installation of a video surveillance camera on the street
Wi-Fi cameras (IP) of video surveillance are digital wireless devices equipped with a CMOS matrix, built-in recorder (function is optional) and video data compression processors.
Information is transmitted over digital data channels using TokenRing and Ethernet networks using IP data protocols.
The principle of operation of the cameras is similar to a computer system that uses routers, local networks and setting up routing through an online network.
The camera is considered a standalone device with an IP address. It broadcasts video and audio signals, compressing information with video codecs for recording on media. It can be a DVR, a computer or a cloud service on the Internet.
The camera is powered from the power supply or from the built-in battery. Models that are able to record data and store them on a separate medium are both video recorders. Other types of cameras work in a network, that is, they do not have a database for storing information.
The video stream is compressed by a built-in compressor: frames (MJPG) and streams (MPEG-4).
Network elements:
Surveillance cameras are connected to a computer or other access point via a Wi-Fi network through routers and routers.
Additional software and drivers are installed. To configure the router, you need to register the parameters of the IP address with the DNS server.
The signal is divided into several categories regarding the range of exposure:
Modern surveillance cameras operate on the basis of the international standard 802.11. Depending on the subtype of standardization, the signal speed will decrease due to the distance when transmitting information. 
The obstacle factor should also be taken into account - waves are reflected from surfaces, for example, if they "meet" with aluminum objects, an echo-like signal may appear. Therefore, for such cases, a repeater is used, which receives signals and transmits them to the next point.
The transmission speed will be reduced due to the time spent passing through the repeater.
To minimize risks, OFDM encoding is installed, which allows signals to pass through walls and basements.
Depending on the viewing angle, devices are distinguished:
Depending on the installation area, the cameras are divided into outdoor and indoor.
Standard equipment of WIFI CCTV cameras consist of:
The design of the camera differs in shape, features of the installation of mounts and protective mechanisms.
Outdoor devices must be equipped with anti-vandal protection.
They have been used in the following areas:
Recently, wireless Wi-Fi has been used as an advertising tool. Used for filming architecture, tourist sites, city attractions online.
Before using the device, you need to test power on and connect to the router. The connection is carried out in the presence of a computer and a Wi-Fi network. Next, enter the network settings. The camera drivers are installed on the computer, the device is started through the software package.
If there are two or more cameras, the connection is made to the same computer. Using the installed navigation software package, several devices are viewed at the same time. The cameras are controlled - rotate, change the angle of inclination, brightness and contrast.
Permanently recording (when this function is available) an image will require the maximum amount of memory (HDD). Therefore, it is necessary to use MJPEG, MPEG-4, H.264 codecs.
To increase the data transfer rate, it is advisable to reduce the image resolution and the number of frames to the minimum acceptable level.
During operation, it is necessary to periodically check the devices for contamination and serviceability of the mechanisms.
To avoid power surges, install uninterruptible power supplies (BIRP).
General Precautions:
If the device is not visible on the computer, it is recommended: If PoE is available, check the operability of the camera by connecting to it via cable. Check network settings (IP address).
If the device does not turn on during a long power outage, you need to restart the camera and restore the network access settings.

Remote access to video surveillance cameras can be wireless or wired. In the first case, GSM, Wi-Fi networks are used. In the second - or similar.
Wired communication is reliable, as it is resistant to external interference (thunderstorm), but it requires material costs for laying wires.
For video surveillance over long distances, the use of wireless communication is justified. It can be used in hard-to-reach places where there are no telephone lines and Internet access points, the only way out is to use cellular communications.
In this case, the cellular operator is connected via the Internet access protocol GPRS or EDGE and an IP address is allocated. The data transfer rate is 5 frames per second at an image resolution of 704 × 576 px.
To maintain confidentiality, receiving information from cameras via the Internet, access to the video signal is protected by a password. It can be multi-level in order to provide different persons with access to only a certain part of the surveillance cameras.
There is a wide range of video cameras on the market for open, discreet and covert surveillance.
Open cameras are installed on the street, parking place and the entrance to the building. Inconspicuous cameras protected by a spherical dome are used in an office, apartment, and trading floor.
