How to connect two surveillance cameras to a TV

If you just need to view live from the camera, then the main question you will have is how to connect a surveillance camera to a TV in order to get an image. For this, you can use the supplied cables, adapters and adapters. You cannot do without additional configuration, for example, a digital camera after connecting the network connector needs to configure the network parameters. A wireless camera that connects to a wi-fi network, and does not need a cable connection, but it needs to specify the parameters of a wireless access point, namely a name and password.

If there is no cable, before answering the question of how to connect the surveillance camera to the Internet, you need to open the wi-fi router access to the Internet and Synchronize all devices with it. And after connecting to the Internet, you can not only transfer all existing recordings from the camera to the cloud, but also to a remote storage. Before connecting the surveillance to the computer, it is necessary to determine which capture card is used on the personal computer and whether it is comparable with PCI or PCI Express slots.

These slots provide stable operation with analog type surveillance cameras and also allow framing. Such boards work on the basis of 4 inputs and are suitable for setting up a private sector surveillance system, for example, in an apartment house or in a country house. Before connecting the surveillance camera to the laptop, you need to make sure that there is enough free space on it to save the recordings.

Surveillance camera: how to connect, configure and ensure stable operation

Among the questions: which surveillance cameras to choose, how to connect to the server and ensure the operation, a special place is occupied by the choice and use of a server, which do not lose their relevance, despite the large number of cloud storage. The server is used with all types of Camerice, it transmits a signal to the surveillance system and functions using a standard BNC input and LAN output. The server allows you to control the entire surveillance system or individual cameras using a personal computer. He will also allow you to give an answer to the question of which one is better to choose for connecting software, how to connect a surveillance camera in the absence of a wireless connection.

How to power the surveillance camera

Before connecting surveillance cameras directly to a cloud storage, TV or computer, it is necessary to ensure uninterrupted power supply in order for the image to be stable and of high quality. Power can be mains or autonomous, as a rule, it is connected using a special socket, which is protected from voltage surges and allows you to work even with an unstable power supply. How to connect a surveillance camera to a TV tuner?

Most often, a USB converter is used for this, which allows you to convert the signal and connect it to any device using a USB cable. This method significantly reduces the cost of connection, but does not provide high image quality.

RCA connection

In the absence of an advanced modification of the TV, you can use the device, which has an RCA signal connection interface. A surveillance camera can also be connected to such a device.

Most IP cameras transmit signals using the BNC connector. Accordingly, it is necessary to ensure the transition from one signal to another. This requires the purchase of two connectors: a regular tulIP connector and a male BNC connector. They can be connected using a 75 ohm coaxial cable. After connecting the adapter on both sides to the camera and TV, you can adjust the signal to the input. This is usually done in AV or Composite mode.

Connection via TV modulator

Quite often, you may be faced with the need to install a surveillance system inside or outside the entrance. In this case, it is required to distribute the signal from one camera to each of the apartments. At the same time, not all tenants will agree to purchase a separate monitor with an HDMI VGA connector, which will allow you to view the image.

Therefore, special devices. television signal modulators. have become very popular in the surveillance market. One such modulator can be installed in each staircase.

The modulator helps to display the picture transmitted by the recorder on any of the TVs present in the building. It should be noted, however, that they must have the same cable TV provider. Otherwise, you need to purchase one modulator for each GoProvider.

The TV modulator works according to a very simple princIPle. It creates an additional stream of information on the TV signal transmission channel, broadcasting at a free frequency. At the same time, the settings are quite capable of making yourself, Using the standard TV menu.

To connect an IP camera to a TV through a modulator, you need to install the latter into a TV cable. This can be done inside the apartment. Using a standard connector, a signal from a recorder or camera is fed into the modulator. Next, you need to set the broadcast frequency. indicate the channel number on the modulator case. And already through the divider at the output of the device, it can be connected to four TVs.

How to connect IP camera to TV?

There are various situations that may require a surveillance camera to be connected to the TV. And the most important reason is the organization of convenient work. When the surveillance system is organized in the house, it is required to constantly turn on and off the computer whenever strangers arrive. And this is not very convenient. If the broadcast of the image will be transmitted to the TV, then you only need to press a couple of buttons on the control panel.

There are several other reasons for synchronizing a TV with an IP camera:

  • In order to save money. For the recorder, you need to purchase a separate monitor, which will be compatible with the camera interface. If connected with a TV, this purchase will not be necessary.
  • When from one camera, for example, at the entrance, the picture is transmitted to several devices, it is also required to Synchronize surveillance with the TV.

Smart TV connection

This option is Most preferable because it is the simplest. As you know, TVs with Smart TVs are quite common, so they can not be called market novelties for a long time. Connecting a surveillance camera to such a TV has the following advantages:

  • Thanks to Smart technology, it is possible to access the Internet directly from the TV;
  • To make it easier to enter information and work on the network, you can use additional accessories, such as mice and keyboards for TVs;
  • Wide screen that allows you to view the picture from the IP camera in detail, even when in another room.

To connect an IP camera to your Smart TV, you need to follow a few steps. On the surveillance service, you need to register an account, and then add all the IP address of the camera there using a unique numbering. In this case, it is possible to group the devices according to their true location or the topic of information transfer. As a rule, the interface of the service is NOT complicated, so it will be easy to select and enable image transmission from one camera in the list.

Next, they set up the TV to enter the Internet according to the data provided by the provider. As soon as it was possible to enter the network, in the search you need to type the address of the surveillance service, enter your personal account and select the required device for viewing.

Connecting MultIPle Cameras to MultIPle TVs

To display images from several IP cameras on a large number of TVs, one modulator will not be enough. This requires a dedicated media server. You can connect it by observing the following sequence of actions:

  • Connect a media server to the TV using the HDMI port;
  • Register a Google Play account for the media server;
  • Download and install on the media server a special program proposed by the manufacturer of the recorder or camera;
  • Go to the program and connect to the device;
  • Search for a transmission channel on the TV, enter it and access the program.

This method has some disadvantages. The main one is NOT a simple installation. After all, it will be difficult to set up a device according to all the rules. Usually a TV user. However, there are also advantages. for example, undocumented media server options. Where it is possible to connect to the network via Wi-Fi, this device will be able to transfer the picture from the IP camera to a smartphone or tablet computer. To do this, you will need to install a special program on your mobile device called IVMS-4500.

How to connect a surveillance camera to a TV?

  • Features:
  • How to connect an IR camera?
  • Connecting multIPle cameras
  • How to View and Stream?
  • Alternative ways

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

Connecting multIPle cameras

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

Analogue security cameras (CCTV) connected to the inputs of the four-channel multIPlexer using RG59 coaxial cable.

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

On the TV end of the cable, the BNC connector can be converted to RCA pin. The MultIPlexer GoPro will then be configured to display 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 surveillance camera to two TVs, you need to split the signal with a CCTV splitter.

How to connect an IR camera?

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

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

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

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 surveillance devices to NVR using Ethernet Cat 5/6 cables;
  • Connect NVR security camera to TV with HDMI cable;
  • Turn 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 the accessories you need to connect your security cameras to your TV are included in the standard NVR package.

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 surveillance system to broadcasting equIPment, you will need either a physical HDML cable connection or some software that broadcasts the streams from the camera from a second location (PC or phone) to the TV.

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

When choosing other connection methods, it is important to consider the brand of TV used for broadcasting. And also the model of the camera itself.

After connecting the surveillance equIPment to the TV from 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.

Once the surveillance cameras are connected to the TV and NVR, the device is ready to broadcast the picture live and save it to the network recorder (NVR). In this case, the router is not used.

There are often situations where 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 GoPro software. When connecting surveillance equIPment to a TV with NVR, this option is excluded. As soon as the user connects all devices using a correct and simple GoPro wiring 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.


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 the surveillance device directly to the monitor.

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

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 on a TV;
  • Using Google Chromecast or Apple TV;
  • Using streaming apps (on Smart TVs).

There are 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, after which 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 have come 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 connectivity and communication with each other. they function 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.

Features overview

Today, many have acquired TVs that support Smart TV technology. It is optimal to connect a digital kit to these models. These TV models allow you to connect a keyboard and mouse, which will facilitate the setup process, and the large screen will allow you to see everything, to the smallest details.

A digital surveillance camera for connecting to a TV is pre-registered with the surveillance service, its serial number is entered and, following the prompts, the image from the camera is activated.

In order to adjust the image on the TV, it is configured to enter the Internet, by visiting the site of the surveillance service, an account is created and cameras are selected for viewing.

The surveillance camera for connecting TV can be analog, while the TV model can support both analog TV and digital. It is important that there is an RCA connection interface.

Many analog cameras have a BNC connector, so an RCA to RCA adapter is required. Having connected the camera and the TV, it is necessary in the settings to activate the reception of the signal, which for many TV models is on the Composite or AV channel.

Surveillance cameras for connection to a TV can be installed both indoors and outdoors. Depending on personal wishes and safety conditions, you can choose models:

With infrared sensor, which activates motion recording;

With different resolutions and viewing angles.

Here you can also arrange delivery to major cities of the country: Kiev, DnIPro, Lviv, Odessa, Kharkov, Zaporozhye, as well as to any settlements of Ukraine by the transport company New Mail.

Analog cameras

The surveillance camera is directly connected to the TV using RCA cables. Their colors will help to make the connection without errors. the yellow cable transmits the signal, and the red and black (white) ones are designed to supply power. 12V and “common”, respectively. When the camera 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 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 will need to split the signal using a CCTV splitter.

Features of connecting the camera to a TV

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

Internal and external

Indoor and outdoor surveillance 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 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.

Cameras equIPped with a rotary mechanism can change the observation area at certain intervals according to a preset program.

Analog cameras

Analog surveillance cameras are considered somewhat outdated, but differ from other types in that they can be directly connected to a TV. Their disadvantage is that 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 camera to the TV directly. you need a registrar.


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

Design features of cameras

Depending on the design, the chambers are:

  • Internal and external;
  • Dome;
  • Miniature.

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

IP cameras

Wireless technology, which is used to transmit images with IP cameras, has developed in parallel with analog technology. It allows you to get a high-resolution picture on the screen, which compares favorably with any analog 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 camera is connected to the TV only through the registrar. 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 surveillance cameras have their own design features.

Types of surveillance cameras

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

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.
