The easiest and most affordable way to organize a video surveillance system is to connect a USB camera to your computer. Naturally, such a solution has minimal functionality, but it is quite suitable for home use.

It should be noted right away that it is unacceptable to use such equipment for professional surveillance (with clear requirements for technical characteristics and safety level).

There are two options for organizing video surveillance via USB:

  • analog equipment connected via a USB converter;
  • classic USB digital cameras (WEB-camera, “webcam”).

In the first case, special equipment is used. a USB converter, which is a compact video recorder (video capture card with a USB interface). Depending on the converter model, you can connect from 1 to 4 analog video cameras to the device.

The advantages of the converter include compact size, easy installation and configuration, and full compatibility with computers and laptops with Windows operating system. The main disadvantages are limited functionality and poor image quality in comparison with full-fledged DVRs.

Classic USB cameras allow you to organize video surveillance in just a few minutes. There are a large number of models on the market.

Preference is given to modern equipment with HD resolution (1280 × 720 pixels) and a built-in microphone. Cheaper 0.3MP cameras can be used, but image quality will be below average.

There are models on sale with built-in infrared illumination for shooting in the dark. As a rule, the IR illumination turns on automatically (there is a light sensor on the equipment case).

The main advantages of digital USB cameras are low price, easy connection and a very wide range of models.


  • minimal functionality;
  • installation restrictions (cable length. no more than 5 m;
  • for large values, a special signal amplifier must be used).


The digital camera (“webcam”) is already equipped with a standard USB connector for connecting to a computer or laptop. Most camcorders are designed for the USB 2.0 standard.

However, models with large-resolution matrices, up to 10 megapixels (for example, Logitech HD Pro Webcam C920), which work better when connected via USB 3.0, are gaining popularity.

The high data transfer rate allows you to realize all the advantages of large picture resolution. It should be borne in mind that saving video files in high resolution requires much more hard disk space.

After connecting the device, you need to install the drivers (usually included or available on the manufacturer’s website), and software to choose from.

The connection of the converter is also not associated with special difficulties. Almost all models are connected to the USB 2.0 connector. To connect analog video cameras, the device is equipped with standard composite RCA connectors (tulip).

Video connectors are yellow, audio is white. The converter can be connected either directly or through a regular USB extension cable.

After connecting the device, the driver and software are installed. It is recommended to use the included software for converters.

Possible problems:

  • No picture. the device is not recognized by the operating system. Solution. reinstall drivers.
  • The camera works intermittently, image freezes, etc. The solution is to check the quality of the USB connection. If an extension cord is used, it is necessary to check the performance of the camera without it (signal attenuation is possible).

In general, a video surveillance system based on USB equipment is quite reliable, while special attention is paid to the technical condition of a computer or laptop.


  • WebcamXP is one of the most popular programs. The main advantages are flexible settings, compatibility with almost all camera models, the ability to use a motion sensor to send notifications by email.
  • Mobile Computer Control. built-in recording scheduler, motion detection, the ability to remotely control a computer via a mobile phone.
  • Xeoma. no installation required (you can run from a memory card), support for all types of cameras, motion detector, alert mode.
  • Ivideon Server is an interesting solution with cloud video surveillance capabilities. If the PC is not connected to the Internet, only the client program can be used to save the video to the hard drive.

All of the above programs were created as affordable analogs of specialized software for security systems. And they are mainly used to organize the simplest home video surveillance. Also, similar software is often installed by owners of small retail outlets to monitor employees and customers.


To implement video surveillance based on USB video cameras, you need to install the appropriate software on your PC.

Most digital USB cameras and converters are sold with a CD containing drivers and software. Also, a minimal set of utilities can be downloaded from the manufacturer’s website.

Transmitter software is usually included in the package. So, the popular model of the EasyCAP002 DVR converter is designed to work with the Super Viewer program.

The software allows you to quickly switch between connected cameras, set up recording by time, take screenshots and save video files to the hard drive of a computer or laptop.

For video surveillance using digital USB cameras, as a rule, third-party software is used, which significantly expands the functionality of even the simplest models. There are both paid and free versions of the programs.

cctv, recording, connect


When choosing a digital USB camera for video surveillance, it is recommended to pay attention to models from well-known manufacturers:

  • Logitech;
  • HP;
  • A4Tech.

For video surveillance at night, it is better to choose a camera with IR illumination (available model. A4Tech PK-333E). An advantage for USB cameras is the presence of autofocus, a built-in microphone and a rotary mechanism for lens orientation.

If there are no special requirements for image quality, you can use the available models with a resolution of the VGA standard.

Since the standard length of a USB camera cable rarely exceeds 1.5 meters, an extension cable is required to determine the optimal installation location. It is not recommended to use low-quality extension cords longer than 5 m.After installing the camera, it is necessary to test the operation of the equipment in all modes.

Any analog video cameras can be connected to the USB converter. When organizing a video surveillance system, you can use several types of cameras:

  • dome;
  • swivel;
  • street, etc.

Considering the limited functionality of systems based on USB cameras and converters, it is recommended to pay attention to more advanced IP video surveillance from a technical point of view.

But with low system requirements, this equipment is the best choice in terms of cost savings. You just need to connect a WEB-camera and install the appropriate software.

Connecting a PC-based DVR

Since the video surveillance system recorder provides monitoring of protected areas using a monitor, connecting the video recorder to a computer is required when remote control of the object is required. The easiest option is to use a computer as a server for a video surveillance system. The PC-based DVR is a video capture card that must be installed in a free slot on a personal computer. The board must meet a number of requirements:

  • The number of inputs must correspond to the number of cameras;
  • The design of the board must be suitable for the given computer;
  • The video capture card must be compatible with the motherboard.

Certain requirements apply to the computer. If it will be used only as a video recorder, for one or two surveillance cameras, you can use a computer that runs on any version of Windows, with a small amount of RAM. A large number of video cameras will require a powerful processor, 2 GB RAM and a high-speed hard drive of 320-500 GB. A small amount of RAM will cause the image to freeze. Analog cameras are connected to the video capture card through a “Tulip” (BNC). SVGA splitter, which allows you to connect up to 8 video cameras per one connector of the card.

The video capture card comes with an installation disc containing a full set of drivers to ensure device compatibility. There is also a working program on the disk that allows you to fully implement all the necessary functions:

  • Recording in the “non stop” mode with simultaneous viewing;
  • Scheduled recording from CCTV cameras;
  • Recording and sending alarm messages when motion sensors are triggered;
  • Sorting the video archive according to the specified parameters;
  • Remote control of the entire system via the Internet.

A video surveillance system, in which a personal computer performs the functions of a registrar, must be reliable and not depend on external factors. Therefore, where interruptions in the work of video surveillance are unacceptable, it is required to connect an uninterruptible power supply in order to protect the complex from the loss of the electrical network. The computer or server of the video surveillance system must also be protected by a password system from unauthorized access to surveillance cameras and to the archive of video files.

Types of DVRs

There are two types of DVRs commonly used in surveillance systems:

  • PC-based DVR;
  • Stand-alone DVR.

PC-based DVR. an ordinary PC with an installed video capture card, to which camcorders are connected.

Stand-alone DVRs are stand-alone devices that record, process and store video material in binary code.

Completely analog devices have become a thing of the past, along with video tape recorders, the video signal to which was also recorded in analog form. Today, in video surveillance systems, inexpensive analog cameras with high recording resolution (AHD) are most often used, the signal from which is converted into digital form, compressed according to one of the algorithms and recorded on the hard disk, therefore all DVRs, even those working with analog cameras, are designated DVR or Digital Video Recorder.

Network NVR video recorders. There is a separate group of devices that do not need to be connected to a computer, since they work on the Internet, by definition. It is an NVR (Network Video Recorder) or Network Video Recorder. Such devices work with digital IP cameras directly, which are connected to the recorder via UTP cable or Wi-Fi.

How to connect the DVR to a computer

Any video surveillance system consists of a certain number of cameras and a basic device that records information from surveillance cameras, organizes a video archive, processes alarms and performs many other functions. Internet technologies make it possible to improve control over objects and make it accessible from any mobile device. An important and demanded function is the ability from any remote point not only to watch the image from any video camera in real time, but also to view the video archive. To do this, you need to connect the DVR to a computer with Internet access.

Connecting Stand-alone DVR to Computer

Stand Alone DVRs

A video recorder of this type is a complete device designed for receiving video signals from surveillance cameras, compressing the signal according to a certain algorithm and recording video files on a hard disk. The recorder also records signals from microphones installed in cameras through audio inputs and processes motion sensors.

Most modern DVRs can be connected to a personal computer using a special cable. On the back wall of the video server housing there is a “NET” connector, through which the DVR is connected to a computer. The computer has the same connector, but it is already used, since through it the computer is connected to the Internet.

In order to connect a video recorder, an additional network card is required. This card is inserted into a free slot on the motherboard and connected with a patch cord to the DVR. The most difficult part of the connection process is the correct implementation of network settings, which may differ for different versions of the operating system. To connect to Windows 7, you need to perform the following sequence of steps:

  • Start;
  • Control Panel;
  • Network and Sharing Management;
  • Change adapter settings;
  • Wireless network connection. 2 clicks.

In the “Status” window that opens, click the “Properties” button and in the window that opens, select the line “Internet Protocol version 4”, then click the “Properties” button.

Attention! the information is approximate, it may differ depending on the manufacturer of the equipment, in your case you can come up with other numbers, the main thing is that the gateway and the address of the registrar match.

Enter the following data in the IP address line:, and in the subnet mask line write the standard digits 255. 255. 255. 0. In the Gateway line, enter the IP address that we will assign to the registrar, for example 192.168. 0.101. Click “OK” and save the changes.

Next, the settings of the DVR are performed. To do this, you need to open the menu and enter the “Network Settings”. In the IP address line, the last digit is changed to, and the subnet mask is entered unchanged. After saving the data, you can connect the recorder using the software.

In the article about video surveillance over the Internet, you can find information about 4 ways to implement online video surveillance, including a separate subsection describing the setup of the DVR when it is connected to a computer. The material is available at the link

After connecting the DVR to a computer and setting it up, you may need a specialized video surveillance program, with which you can not only view the image from cameras, but also keep an archive, set up recording according to motion, schedule, noise, and also implement remote video surveillance via the Internet.

Video surveillance using cloud services is rapidly gaining popularity today. This is not surprising, since to implement remote access to cameras using the cloud, you do not need to obtain a dedicated IP address and configure a router. just connect the camera to a computer, and it performs all the necessary settings on its own. Of course, this will require specialized cameras with firmware for a specific service. You can learn more about this from the article about cloud video surveillance.

Connecting the DVR to the Internet

Diagram of connecting the DVR to a PC and the Internet

The DVR can be connected to the Internet directly, since the device has a “LAN” port, but it is impractical to use a dedicated line for this purpose, so this connection is best done through a router. First of all, you need to get a static address from your ISP. This service is paid, but the amount is insignificant. It happens that the router has already been assigned not a dynamic, but a static address, then the connection process is simplified.

Data transfer rate. When working with a video surveillance network via the Internet, it is necessary to take into account the data transfer rate, since at a speed of less than 2 Mbit / s, the picture may be distorted or freeze. Image quality directly depends on traffic speed.

Method without a static IP address. If your ISP can only provide a dynamic address, you should use DDNS technology, which allows you to associate a dynamic address with a domain name. In other words, the router regularly informs the external server of its dynamic (constantly changing) address, and the device is assigned a permanent domain name. When a user loads this domain name into the browser, the service redirects it to the last received address of the router. The connection is established, and the user can enter his video surveillance system from anywhere and receive the necessary information.

DDNS services. There are several services that allow the user to get a domain name and work on the Internet with a device with a dynamic address. One such site is “”. The service is free and to use it, you need to follow the link, register a new account. “Create Account” and fill in all the required fields. According to some reports, the service behaves incorrectly with postal addresses. therefore, it is best to register a mailbox on Yandex or Gmail to work with this service. After registration is complete, a link to activate your account will be sent to the mailing address. Then you need to enter your username and password and configure the host. The last procedure is to configure the router itself.

To connect the DVR to a computer, you can use the capabilities of the USB port, but this can only be implemented with a certain type of device.

Connection problems

During the connection process, it may turn out that the computer does not see the DVR. Most often this happens due to incorrectly installed options, so the first thing to do is reset all settings and reinstall everything carefully. In some cases, the cause may be incorrect pinout of the LAN cable. Some recorder models have their own settings that must be carefully observed. In rare cases, the cause of an incorrect connection can be an anti-virus program or a firewall.

How to connect a security camera to a computer

An IP camera is a network device that transmits a video stream via the IP protocol. Unlike analogue, it broadcasts an image in digital format, which remains so until it is displayed on a monitor. Devices are used for remote control of objects, so below we will tell you how to connect an IP camera for video surveillance to a computer.

How to connect an IP camera

Depending on the type of device, the IP camera can connect to a PC using a cable or Wi-Fi. First, you need to configure the local network parameters and log in through the web interface. You can do this yourself using the built-in Windows tools or by installing special software on your computer that comes with the camcorder.

Step 1: Setting up the camera

All cameras, regardless of the type of data transfer used, are first connected to the network card of the computer. This requires a USB or Ethernet cable. As a rule, it comes with the device. Procedure:

  • Connect the camcorder to your PC with a dedicated cable and change the default subnet address. To do this, launch the “Network and Sharing Center”. You can get to this menu through the “Control Panel” or by clicking on the network icon in the tray.

In the left part of the window that opens, find and click on the line “Change adapter settings”. The connections available to the computer are displayed here.

For LAN, open the Properties menu. In the window that opens, on the “Network” tab, click on “Internet Protocol version 4”.

  • In the window that appears, enter your username and password. For example, “admin / admin” or “admin / 1234”. The exact authorization data is in the instructions and on the manufacturer’s official website.
  • Open a browser and enter IP cameras in the address bar. Additionally, specify the authorization data (login, password). They are in the instructions, on the sticker of the device (in the same place as the IP).

    After that, a web interface will appear, where you can monitor the image from the camera, change the basic settings. If you plan to use several devices for video surveillance, then connect them separately and change the IP address of each in accordance with the subnet data (via the web interface).

    Step 2: Viewing the image

    After the camera is connected and configured, you can get an image from it through the browser. To do this, you just need to enter its address in the browser line and log in using your login, password. It is more convenient to carry out video surveillance using special software. How to do it:

      Install the software that comes with the device. Most often it is SecureView or IP Camera Viewer. universal software that can be used with different video cameras. If there is no driver disk, then download the software from the manufacturer’s official website.

    A list of available models with detailed information (IP, MAC, name) will appear in the list. If necessary, you can remove the connected device from the list.

    Click on the “Play” tab to start watching the video stream. Here you can configure the recording schedule, sending notifications, etc.

    The program automatically remembers all the changes made, so you don’t have to re-enter the information. You can configure different profiles for monitoring as needed. This is convenient if you use more than one camcorder, but several.

    Connection via Ivideon Server

    The method is relevant only for IP equipment with Ivideon support. It is a software for WEB and IP cameras that can be installed on Axis, Hikvision and others.

      Create an account on the official Ivideon website. To do this, enter your email address, password. Additionally, indicate the purpose of use (commercial, personal) and agree to the terms of service and privacy policy.

  • Run the Ivideon Server distribution kit and install the software on your computer. Change the path if necessary (by default, files are unpacked to “AppData”).
  • Open the program and connect the IP equipment to the PC. A wizard for automatic configuration appears. Click “Next”.
  • Create a new configuration file and click Next to proceed to the next step.

    Log in with your Ivideon account. Enter your email address, camera locations (from the drop-down list).

    The automatic search for cameras and other equipment connected to the PC will start. All found cameras will appear in the list of available ones. If the device is not yet connected, then connect it to the computer and click “Search again”.

    Select “Add IP Camera” to add the equipment to the list of available ones yourself. A new window will appear. Here specify the parameters of the equipment (manufacturer, model, IP, username, password). If you plan to work with multiple devices, then repeat the procedure. Save your changes.

    Click “Next” and go to the next step. By default, Ivideon Server analyzes incoming audio and video signals, therefore, it starts recording only when it detects suspicious noise or moving objects entering the camera lens. Optionally enable archive recording and specify the location for storing files.

    Confirm the entrance to your personal account and add the program to startup. Then it will start immediately after turning on the computer. The main program window will open.

    This completes the configuration of the IP camera. If necessary, you can add new equipment through the main screen of Ivideon Server. Here you can change other parameters.

    Connection via IP Camera Super Client

    IP Camera Super Client is a universal software for managing IP equipment and creating a video surveillance system. Allows you to view a video stream in real time, record it on a computer.

      Run the distribution kit of the program and continue the installation as usual. Select the location of the software, confirm the creation of shortcuts for quick access.

    Open IP Camera Super Client from the start or desktop shortcut. A Windows Security Alert appears. Allow SuperIPCam to connect to the Internet.

    The main window of the IP Camera Super Client appears. Use a USB cable to connect the device to your computer and click “Add Camera”.

    A new window will appear. Go to the “Connect” tab and enter the device data (UID, password). They can be found in the instructions.

    Go to the “Recording” tab. Allow or disallow the program to save the video stream to your computer. After that click “OK” to apply all changes.

    The program allows you to view images from multiple devices. They are added in a similar way. After that, the image will be broadcast on the main screen. Here you can control the video surveillance system.

    To connect an IP camera for video surveillance, you need to configure the local network and register the device via the web interface. After that, you can view the image directly through the browser or by installing special software on your computer.

    Features of the

    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 the part of the territory that interests the 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 CCTV devices transmit analog or, as it is also called, composite video signal, the video is directly compatible with TVs that have RCA composite video 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 with pre-fabricated Siamese 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.

    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 a TV, you need to complete only 4 steps:

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

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

    Directly connecting the NVR system 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:

    • simple connection;
    • large storage space and 24/7 recording;
    • work without a network (without connecting to a router);
    • stable signal;
    • simple control.

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

    After trying and testing all kinds of methods for connecting a security system to a 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 the TV that is used to broadcast the video, as well as the model of the camera itself.

    After connecting the video surveillance equipment to the TV with 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 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 software. When connecting video surveillance equipment to a TV with NVR, this option is excluded. As soon as 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 other monitor), you can easily update all IP cameras at the same time using the NVR operating system.

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

    Analogue security cameras (CCTV) are connected to the video inputs 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 to be used 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 with a CCTV splitter.

    How to connect a CCTV camera to a TV?

    Sometimes customers 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.

    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 the time spent testing multiple methods. It is also important to consider information that a TV or monitor may not be compatible with CCTV cameras.

    There are video surveillance systems that 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 information technology development, 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 to connect and communicate 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.

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

    Microphone connection diagrams to video surveillance systems

    The simplest technique for connecting external microphones is to use the dedicated connectors and connection points found on the camera. You just need to see which cable is suitable for a particular device. When connecting the power supply and the fixing audio device, you need to determine the place of contact by the color and purpose of the wire and connection points.

    Usually only two interfaces are needed for operation: tulip “dad” and 5V for the power supply. The latter type can be male or male, depending on the cable that needs to be taken from the power supply. The connection diagram itself usually looks like this:

    • black cables connect each of the three interfaces. this is the GND signal. according to the designation in the diagram, but in simple words. it must be connected or soldered to the outer skirt of the tulip wire, to the power supply connector. After that, all cables are connected at a single point;
    • GND, or red cable. designed to connect wires of the same color to the connector and the microphone, which goes to the power supply;
    • the signal wire of the microphone is yellow, soldered to the tulip tip, which is the closest point on the connectors.

    The connection diagram is complicated exclusively in words. During installation, you only need to make sure that all three system cables are soldered to the black wire. If you do this manipulation first, then the rest of the contact scheme will not allow you to make a mistake during connection.

    When the soldering is completed, then you can directly connect the microphone to the IP camera. It is routed to the connectors that most models of this type are equipped with. The tulip, with which the connection is made, must be installed with a sting in the blue light socket, after which voltage is applied to the interface for the power supply.

    It is important to note that this connection is only relevant if the device provides for retrofitting. If it is not possible to carry out such manipulations with the equipment, then you need to use a separate channel, for example, a signal is sent to the sound cards of the computer. A person without special technical knowledge will not be able to perform such a job.

    Key nuances of connecting a microphone to a camera

    It must be remembered that the main subtleties are not soldering the wiring diagram, but directly providing a stable and reliable signal transmission channel to the camera. Usually, wires of various purposes are used for this, and for laying indoors, you can use a twisted pair or telephone cable. The main problem is that such lines have low protection against interference, therefore, they significantly distort the signal with increasing voltage.

    With the help of a twisted pair cable, a reliable route can be created, the length of which is up to 1.5 meters, but it is not desirable to create a line over 1 meter. To create longer lines, you can use the coaxial type. The desoldering process using such equipment is somewhat more complicated. A distinctive feature is that the common GND- wire, in addition to the three points of the power supply, microphone and camera tulip, must be soldered to the coaxial cable, which will eliminate various interference. The type and quality of the cable depends on whether you plan to install indoor or outdoor.

    The subtleties of installing a microphone in video cameras

    Connecting a microphone with your own hands is quite simple and usually it does not cause any difficulties. All products are provided with detailed instructions with installation diagrams, special connectors for cameras, and a compact body minimizes the complexity during installation in any required place. The main difficulties arise if you need to connect a microphone for video surveillance, which is provided without an external housing.

    The wire-type model is a compact-sized sound conversion module, from which a series of wires emerge, through which the connection is made. The difference in connection depends only on which connectors are used for connection. You just need to study all the documentation that comes with audio signal processing to determine exactly which interface is provided for the contact.

    How to connect a microphone to a camcorder?

    If you decide to connect a modular microphone to a CCTV camera, you need to carry out all the work as carefully as possible, choosing the right components.
