This will allow you to sit on the couch broadcasting photos taken on vacation or a video on the big screen. You can also play your favorite games using not a small laptop display, but display a picture on a device with a huge diagonal. However, in the latter case, it is worth considering that the picture will be broadcast to the TV with a slight delay. You won’t notice this when watching movies and photos. Below we will give step-by-step instructions on how to connect a laptop to a TV via WI-FI.

What you need to connect a laptop to TV via Wi-Fi

Many people ask the question: how to connect a laptop to a TV via WI-FI? The main condition for the possibility of such a connection is the presence in the TV itself of Smart TV technology and a Wi-Fi module with support for Wi-Fi Direct and DLNA functions. The first allows you to connect a laptop to a TV directly, without using a home network and a router. However, laptops can connect to all TVs (especially older models) in this way. Second technology. DLNA, makes it possible to go from the TV itself to the network storage (for example, a folder on the hard drive of a PC connected to a home network) and start playing multimedia content from it. viewing a photo or video. You can also launch the media server from the laptop itself from the broadcast to the TV.

The difference between These two connection methods is quite significant and below we will tell you what is the difference and how to organize such connections and how to connect a laptop to a TV via WI-FI.

Connecting to a TV via Wi-Fi Direct

This feature works well on modern TVs from the 5th generation, where manufacturers have already implemented unified wireless direct drivers. This is so N. Connecting a second wireless monitor, where the TV acts as an external display device for everything that happens on the screen of your mobile device, such as a laptop or smartphone.

In the first case, you need to have Windows 7, 8 or 10. A home network is NOT required for this connection, and authentication and connection is carried out through a connection request on the TV screen itself.

Such a connection is convenient because you can see on the big screen everything that is done on the screen of your PC or laptop, including working in the browser, viewing photos or videos, as well as the process of playing. The only drawback here is a slight delay in displaying content on TV and slightly fewer colors than on a PC display.

How to connect a laptop to a TV via WI-FI? Wi-Fi Direct connection is quite simple. To do this, turn on your TV and laptop. Wi-Fi adapters must be activated on both devices.

Now on your Windows 10 laptop go to Start | parameters | system | Display ”and on the right side under“ Multiple displays ”click on“ Connect to a wireless display ”. A vertical shutter with the “connect” menu and a list of detected devices will appear on the right side. In our case, this is Samsung 6 series (49). Click on the selected model, then on the TV itself, agree to the connection request. It should be noted that the connection may not occur from the first or even from the second attempt, because K. The computer needs time to transmit the TV signal encryption keys. But after the TV is connected to the laptop via WI-FI, you can broadcast the video even from another room.

In order to disable the transmission of the wireless video signal to the TV, click on “Connect to wireless display” again and in the right curtain of the menu click on the “Disconnect” button.

Connecting to TV via DLNA

This type of connection consists in the fact that on a computer or laptop, included in the home network, access to certain folders is organized where you are placing multimedia files. Photo and video. Only your TV can play them with its built-in player. The condition for this is that the TV supports DLNA technology. a set of standards that allow devices connected to a home network to transmit and perceive various media content.

This can be done both from an Android smartphone and tablet, as well as from a TV (playback functions only). The question also arises of how to synchronize a laptop with a TV via WI-FI. In general, everything happens automatically.

The main task. organize a shared folder on the laptop. To do this, you need to make it available to other devices on your home network, as well as assign constant IP addresses in the router for gadgets connected to the network. This is necessary so that the TV does NOT have to Scan the network every time to find this folder.

To do this, create a shared folder named in English on the laptop’s hard drive, for example, MediaTV. Go to the “Access” tab in its properties. Next, click “Advanced Settings”, put a check mark next to the phrase “Share.” and Confirm the action by clicking “OK”.

If your TV with Smart TV is old model and its system does not allow to connect to devices on Windows OS, viz. the TV simply does not see the shared folder with files, there is another option to organize the broadcast of media content on its screen. But first you need to make sure that your TV is visible on your home network.

To do this, click on the “Network” icon in the Explorer on the left. After that, the devices available on the network will be displayed in the right pane. Now select a video file in MP4 format in any folder, right-click on it and select “Transfer to device” in the context menu, in our case to Samsung.

This will launch the Windows media server, which will display a list of files transferred to the TV. Don’t miss the request on the TV itself to play a file from an external source.

Connecting using Wi-Fi adapters

If you failed to connect the laptop to the TV via Wi-Fi, but this method remains more preferable for you, as compared with the HDMI connection, you can try to connect the laptop to the TV using an intermediary. TV set-top boxes on Android or Wi-Fi dongle, for example, Google Chromecast. In this case, you just need to connect to the Wi-Fi network organized by this adapter and broadcast the signal to it.

How to connect a CCTV camera to a TV?

Sometimes buyers do not want to save a video recording from a video surveillance system. they need it to be immediately displayed on a TV or monitor. This article explains how to connect a CCTV camera to a TV (monitor), and what equipment is needed for this.

Features:

Using a security system without recording, the user receives a number of advantages:

  • You can check at any time who is on the doorstep of your home or office;
  • View in real time that part of the terrain that interests you most;
  • It is possible to connect a video surveillance device directly to the monitor.

This method is used both in the private sphere and in commercial organizations. For this reason, connecting a camcorder directly to a TV or monitor is considered the most popular and affordable.

How to connect an IR camera?

Since video surveillance devices transmit analog or, as it is also called, composite video signal, the video is directly compatible with TVs that have a composite video RCA input.

To connect, you need a Siamese cable (twisted pair). it is used most often. If the installer does NOT know in advance the length of the wire to be prepared, a spool of RG59 coaxial cable can be used. In the latter case, only the required amount of cord can be cut.

CCTV device video output and power are connected to pre-fabricated Siam coaxial cable.

When the user wants to view live video from the security system, he simply selects the RCA video input.

If the user also wants to hear the sound on the TV, he can connect a standalone audio surveillance microphone to one of the RCA inputs of the TV.

Connecting multiple cameras

In addition to analog CCTV cameras, you can connect high definition CCTV objects (AHD CCTV) to the HDMI input of a television monitor.

If you need to view multiple cameras on TV at the same time, you should use a quad-core CCTV processor (up to 4 cameras) or CCTV multiplexer (up to 16 pieces) to combine video signals.

Analog Security Cameras (CCTV) are connected to the video input of the four-channel multiplexer using RG59 coaxial cable.

The multiplexer has one BNC video output. Can use RG59 wire to trigger video from multiplexer to TV.

On the TV end of the cable, the BNC connector can be converted to RCA pin. The multiplexer processor will then be configured to display video from all 4 cameras on the screen. It can also be configured for a different purpose:

  • Scrolling a single image with a delay;
  • Pictures in picture;
  • Double pictures.

Many users are interested in the question of whether it is possible to connect one security camera to two TVs or monitors. The answer in this case is yes. To connect one analog CCTV camera to two TVs, you need to split the video signal using a CCTV splitter.

How to View and Stream?

There are a number of differences between an analog camera and an IP camera. The latter broadcast a better picture and are equipped with additional intelligent functions. To connect cameras to your TV, you need to complete only 4 steps:

  • Connect video surveillance devices to NVR using Ethernet Cat 5/6 cables;
  • Connect NVR security camera to TV with HDMI cable;
  • Power on the NVR using the power adapter;
  • Turns on the TV, after which a live image appears on the screen.

As a result, there is no need to download an application and no need to connect to a router. All accessories you need to connect security cameras to your TV are included in the standard NVR package.

Connect the NVR system directly. this is by far the easiest way to pair your security camera and TV.

There are 5 main reasons why a user should choose an NVR system to connect a security system to a TV:

  • Easy connection;
  • Large storage space and 24/7 recording;
  • Work offline (without connecting to a router)
  • Stable signal;
  • Simple controls.

To connect a CCTV system to broadcasting equipment, you will need either a physical HDML cable connection or some software that broadcasts the video stream from the camera from a second location (PC or phone) to the TV.

After trying and testing all kinds of methods for connecting the security system to the TV directly, users have identified the most popular methods that are most profitable to use. The most convenient. NVR system.

When choosing other connection methods, it is important to take into account the brand of the TV used to broadcast the video, as well as the model of the camera itself.

After connecting the video surveillance equipment to the TV with the NVR, you can both view the picture from the cameras online and record the image. For example, the Reolink RLK8-410B4 can record continuously for several weeks at 4MP Super HD resolution. But you can choose a lower resolution. then the recording can take longer.

After connecting the CCTV cameras to the TV and NVR, the device is ready to broadcast the picture live and save it to the network video recorder (NVR). In this case, the router is not used.

There are often situations when the user tries to connect security equipment to the TV, but receives a warning that there is no signal. This mainly happens when connecting security systems to the TV using third-party software. When connecting video surveillance equipment to a TV with NVR, this option is excluded. Once the user connects all devices with a correct and simple wired connection, an online picture with good signal quality will appear on the screen.

Easier to manage security cameras throughout the system. For example, after connecting to a TV (PC or second monitor), it is easy to update all IP cameras at the same time using the NVR operating system.

Alternative ways

If you need to connect a security camera without NVR, then there are the following options:

  • Using an IP camera to HDMI converter or decoder;
  • Setting up a DLNA server on a PC and broadcasting IP video on a TV;
  • Using Google Chromecast or Apple TV;
  • Using streaming apps (on Smart TVs).

It is also worth considering the risks of connecting CCTV cameras to a TV without an NVR. For example, these include time spent testing multiple ways. It is also important to consider the information that a TV or monitor may NOT be compatible with CCTV cameras.

There are video surveillance systems, which are the easiest to connect. They will be discussed below.

  • Poe. RLK8-410B4. Connecting your security camera to your TV is easy with the RLK8-410B4. To do this, connect the NVR to the TV using the supplied HDMI cable, and then a live image will appear on the screen. Make sure all devices are turned on and connected correctly.
  • Reolink RLK8-410B4. It is an 8-channel PoE security system. Consists of 4 5MP / 4MP security cameras. HDD 8 TB, 8 channel NVR for 24/7 recording.

In the process of observing the history of the development of information technology, users came to the conclusion that today it is better to use cameras with built-in WI-FI or NVR system. The good news is that Reolink NVR works with both Reolink wireless cameras and PoE, so in this case it is possible to mix and match different types of devices.

Wireless security cameras DO NOT need Wi-Fi connection and communication with each other. they operate over a private network that does not require the Internet. You just need to turn on the NVR and cameras and they will start working.

Video on how to connect a CCTV camera to a TV, see below.

How to connect your camera to your TV. Step-by-step instructions. Required tools and materials

To obtain a high-quality image, in addition to the camera and TV itself, you must have a power supply and corresponding connecting cables and connectors to them.

The quality of the connecting cable depends on the efficiency of the picture on the screen.

Soldering the appropriate wires to the cable routing will produce a good signal.

Use only good quality power supplies. Domestic blocks have proven themselves best of all, which are much more durable than their Chinese counterparts.

Power supplies BP-1A or BPM. 1A are used to work with electric radio equipment consuming a rectified stabilized 12-volt voltage, the current strength of which does NOT exceed 0.7 amperes. Their optimal operation at an interval of positive temperatures from ten to forty degrees Celsius and a relative humidity of no more than 80 percent.

The power rating is indicated on the body of each camera. For example, the inscription 9-15V DC / 0.1A says that the device requires a constant voltage with a range of 9 to 15 volts with amperage. 0.1 ampere.

In particular, in this situation, a power supply with an output voltage of 12 volts and a maximum current of one ampere, that is, above the specified parameter, is suitable. 0.1 A. When more than one device is short-circuited to one unit, their permissible current should be summed up.

Connection diagram (connection methods)

You can connect the camera to television equipment in different ways, depending on the presence of an interface in a particular TV model.

The interfaces can be as follows:

  • SCART.
  • RCA.
  • HDMI.

The first is the oldest, some modern camcorder manufacturers have already abandoned it, but they still come across on TVs with it.

The connection is carried out using a SCART cable, then in the TV menu function we find the Mode corresponding to this interface and a video image should appear on the screen. AV function is selected on tube TV. Transmission signal analog.

The second version of the interface is the most widespread. The signal is transmitted using three wires: white and red. sound, over yellow. video. The connection is made according to the color of the connectors. As in the first case, they search for the corresponding mode in the TV menu.

In the case of the tube model, turn on the AV function. Many people use an RCA connector, also called a composite connector, to connect not only a camera, but also other devices to a TV: music speakers, a DVD player, etc. It should be remembered that a cheap, poor quality RCA cable can quickly break and come out of building.

Models of the latest generation are equipped with the third option. The connection method is similar to the above, but a digital signal is transmitted through this interface. The picture quality is much higher.

Thus, to connect a video camera to a TV, a conventional analog video camera can be used, the cost of which is much lower in comparison with an IP camera. A 12 volt power supply is used to power the security camera.

Equipping the TV with a webcam

Not everyone needs to equip their TV with a webcam or, as the people say, a webcam. However, if your TV is from the latest models and has Smart TV technology, there is a unique opportunity to use it for free communication with your friends, including nonresidents, via Skype.

To organize video conferencing and visual communication, you need to connect a web camera to the TV. It differs slightly from those used with computers.

If the television set has functions for receiving signals other than analog, then it is not possible to connect to it a conventional webcam equipped with a USB interface. This can be done only after adding a special system unit used as an adapter.

Connecting a CCTV Camera Directly to a TV

Over the past few years, video surveillance has become part of the everyday life of the population of many countries of the world. With the help of a small specialized video camera, you can easily find out what is happening directly at the front door, on the staircase, in the yard of the house, where the child is walking and / or the car is parked. By organizing a simple video surveillance system in your apartment, you can significantly increase your own security.

Types of CCTV cameras

In the modern electronic equipment market, there are video cameras that differ in different video surveillance technologies. They differ from each other in the way of image transmission and connection to a TV.

Analog video cameras

Analog CCTV cameras are considered somewhat outdated, but differ from other types in that they can be directly connected to a TV. Lack of them. the image on the screen has a low resolution, which does not allow the owner to see the small details of the picture.

Further development of analog technology has led to the emergence of TVI / HDCVI / AHD cameras that allow you to get a picture on the screen with a fairly high resolution. In this case, you cannot connect the camcorder to the TV directly. DVR required.

There are high-definition CCTV cameras equipped with a switch that allows them to switch to high-quality analog video mode. They can be connected directly to the TV.

IP video cameras

The wireless technology that is used to transmit the image of an IP video camera has developed in parallel with analog technology. It allows you to get a high-resolution picture on the screen, which sets them apart from any analog video camera. However, they are much more complicated and more expensive than analog ones, since they contain built-in digital filters that can significantly improve the image quality. In addition, a microphone and a speaker can be mounted in the housing.

The IP video camera is connected to the TV only through the DVR. Without the latter, it can be connected to a computer, tablet, smartphone that has special software. Remember:

  • IP cameras have their own firmware;
  • To connect you need a computer network;
  • Connection to a computer network is carried out using an RJ45 connector;
  • IP cameras can be equipped with WI-FI interface.

All CCTV cameras have their own design features.

Design features of video cameras

Depending on the design, the cameras are:

  • Internal and external;
  • Dome;
  • Miniature.

In addition, all video cameras are divided into black and white, color, mixed.

Internal and external

Indoor and outdoor CCTV cameras are designed for indoor or outdoor installation. At the same time, the internal ones do not have protection against external factors and are distinguished by their small size and low weight. External ones are mounted in special enclosures that allow them to work in any climatic conditions and protect them from external factors (vandals, etc.). As a rule, external video cameras are installed far from the monitor, and therefore they must transmit a signal over long distances.

Box-type cameras, in turn, can be fixed and rotary. In rooms, motionless ones are installed on brackets, and on the streets they are placed in a special thermo-casing with heating and ventilation. If it is necessary to monitor large areas, they are equipped with a wide-angle lens with a zoom.

Video cameras equipped with a rotary mechanism can change the observation area at certain intervals according to a preset program.

Dome Cameras

Dome cameras have an attractive appearance and can be installed both indoors and outdoors. The rest of the species are distinguished by the presence of a high-speed rotary mechanism, which can move the zoom lens both vertically (180 °) and horizontally (360 °), allowing you to control areas with fast-moving objects.

Minicamera

Mini cameras are used for covert observation, for which they are hidden, for example, in interior items in such a way that the device could not be noticed. The lens is NOT larger than the eye of the needle, therefore the observation area is limited to small dimensions.

The matrix of black-and-white cameras has a high light sensitivity and high resolution, which allows them to be used wherever a detailed picture is needed. Color details provide a color video picture, which makes the image on the screen more informative. Mixed cameras have the ability to change the color depending on the time of day. At the same time, high-quality night shooting is carried out using IR illumination.

Features of connecting a camcorder to a TV

To quickly and easily connect a CCTV camera to a TV, you need to acquire consumables and accessories. over, their composition is determined by the type of video camera, its interfaces and the scope of delivery. The TV should at least have an analog RCA video input. At the same time, most camcorders are equipped with RCA connectors.

Analog video cameras

The CCTV camera is connected directly to the TV using RCA cables. Their colors will help to make the connection without errors. the yellow cable carries the video signal, and the red and black (white) cables are for power supply. 12V and “common” respectively. When the camcorder is removed from the TV, you can extend the RCA cable using an RG59 coaxial cable or twisted pair (Siamese cable).

To connect high fidelity analog cameras (TVI / HDCVI / AHD), you need an analog video recorder DVR.

To connect multiple cameras to one TV, you will need to purchase a 4-core processor or CCTV multiplexer. To connect one analog camera to multiple TVs, you need to split the video signal using a CCTV splitter.

IP video cameras

To connect the IP camera, the user will definitely need a network video recorder NVR. In this case, to connect cameras to the TV, you must perform the following steps:

  • Connect the IP cameras to the NVR using an Ethernet Cat 5/6 cable;
  • HDMI cable connect NVR to TV;
  • Connect the AC adapter to the NVR;
  • Turn on the NVR and TV.

After performing THESE operations, a live image will appear on the TV screen.

The network video recorder NVR allows you to make a number of fine settings: motion detection, face detection, alarm outputs, etc. A number of models are equipped with PoE outputs, which allow you to connect CCTV cameras without a power adapter.
