How to fix a WEB-camera on the monitor

CCTV Camera Monitor

web-camera, monitor

For mounting security systems, 2 main types of monitors are used:

  • LCD (created using liquid crystals);
  • CRT (on a cathode ray tube).

The choice of the monitor is made after purchasing all other devices. Despite the fact that many consider CRT monitors to be obsolete, they can also be effectively used in tandem with cameras. They have their advantages:

  • cheapness;
  • low screen inertia;
  • good display quality of dynamic (moving) objects;
  • large viewing angle (up to 180 degrees).

Fans of LCD monitors are also guided by objective reasons:

  • compactness;
  • low energy consumption;
  • lack of flickering in the image;
  • high quality color reproduction;
  • increased, in comparison with ray screens, image brightness.

Screens on a ray tube usually have a higher resolution (about 1200×1600 pixels), while budget LCD models have fixed lower rates that “eat up” details.

At the same time, LCD monitors have a constant frequency, they do not flicker, which makes them more comfortable for eyesight. Also, they do not produce radiation harmful to the human body. The same level is achieved only in new more expensive models of CRT screens.

How to display a WEB-camera on a monitor

CCTV cameras are by far the most effective way to protect your home or place of work from unauthorized entry. Due to the reduction in for analog devices, almost any resident of Russia can afford to install cameras.

The simplest option is to connect a CCTV camera to a monitor. Which is easy to do on your own, while at the same time it will provide constant supervision of the house, apartment or office. The monitor will display images from all cameras.

In order for the video surveillance system to function correctly and not fail in the first month of operation, you need to make sure that all components are selected and connected correctly.

Connecting an analog camera to a monitor

To correctly and effectively connect the monitor to the camcorder, you need:

  • connecting cables;
  • Power Supply.

It should be understood that the quality of the image and the durability of the system largely depend on the quality of the cable used. Not worth saving. It is better to spend money on an expensive cable once than to periodically repair the entire system. To connect analog cameras, usually a coaxial cable is used.

There are 3 ways to connect a monitor and a video camera:

  • using a video recorder;
  • via PC settings (video capture card);
  • direct connection.

The first method is justified when organizing surveillance, which involves a large number of video cameras. For systems consisting of 1 or a pair of cameras, it is not justified due to the high cost of the DVR.

Connection diagram of the monitor to the recorder

To connect cameras using a personal computer, you need a special video capture card or a USB converter, which also implies additional expenses.

The best option for monitoring a house or apartment would be to connect the camera directly to the monitor. This method will allow you to observe on the monitor what is happening in the surveillance area of ​​the camera at the moment. Online image viewing on the Internet will be unavailable.

You can use the screen of an ordinary personal computer, that is, the camera can be connected to an ordinary computer monitor directly. In addition, you only need to purchase a BNC-VGA converter. It converts the analog camera signal to digital, which allows you to get the picture on the screen in real time. When buying it, it is important to pay attention to the resolution, which rarely exceeds 740×567 pixels. This means that regardless of the screen resolution, some of the quality will be “eaten” by the device. Higher quality converters will cost more.

BNC-VGA Signal Converter

To connect to the screen, it must have a composite signal connector. In it, the central contact feeds directly the video signal, and the external one. the screen.

When connecting analog CCTV cameras, it is worth remembering that they usually have wire leads or a BNC connector. This means that you need to make a suitable adapter to connect. Then BNC is installed on one side of the connecting cable, on the other. tulip (RCA) and they are connected. Voltage level. 75 Ohm.

It is also recommended to look at the passport of the device, especially if the camera has 4 outputs. Most often this means that two double wires will come out of it. Usually yellow is a signal, red is a power supply plus. The remaining two wires can be connected together. However, it is best to carefully read the passport of the device so as not to break the device.

  • press “source” on the remote control;
  • select “composite” or “av” mode on the TV screen.

If you connect an ip-camera to a monitor, just a personal computer is enough, a cable (twisted pair) goes from the ip-camera to the computer’s network card (rj45). Install software from the manufacturer’s ip-camera. that’s all. It is not necessary to additionally connect the monitor, since it is already connected to the PC.

Customers often contact us with the question of how to display the image from the DVR on a monitor located at a great distance. For example, it is necessary that the video recorder is in the house, and the monitor is at the checkpoint at the guard. Or another example, when the image needs to be displayed from the DVR at the same time in different rooms.

The simplest thing that comes to mind in such a situation is the use of HDMI extenders over UTP cable. However, the cost of such devices is high when it comes to distances greater than 50 m.Also, you need to remember about scrupulous handling of such devices. in case of an incorrect on-off sequence of circuit nodes using HDMI extenders, their failure or incorrect display on the monitor is possible. In addition, do not forget about the need to use a high-quality UTP 6 cat cable. And I would also like to have camera control, for example, to enlarge the picture, but with this solution you will only have an image.

Let’s consider the case when IP cameras and network video recorder (NVR) are used. The solutions in this situation are simple, due to IP technologies. connect a computer with a client program to the network (for example, iVMS-4500 for Hikvision devices) or use a web browser to display the image. If you do not want to use a computer, then you can install an additional video recorder, to which you also need to add existing IP cameras. It turns out a scheme when both registrars work simultaneously with the same IP cameras, as shown in the figure:

Well, if you use HD-TVI or analog cameras and a video recorder (DVR) Hikvision or HiWatch, then what?. you ask. Use an additional recorder and also connect a coaxial cable from each camcorder to it? Not at all. To display images at a long distance on an additional recorder, we can use digital video channels from the first recorder.

Below we will describe in detail how to do this. HiWatch DS-H104G is used as an example of the first recorder, to which three HD-TVI cameras are connected. The additional recorder will be HiWatch DS-H108G. Both registrars are connected to the same IP network. HiWatch DS-H104G recorder has IP address 192.168.1.33.

Go to the settings of the additional HiWatch DS-H108G recorder via the Internet Explorer web browser and go to the System-Controlling Cameras section. Switch three channels to IP mode (uncheck) and save:

Go to the System-Controlling Cameras section and select the “IP Camera” tab and click on the “Add” button.

In the window that appears, specify the data of the main HiWatch DS-H104G recorder. IP address 192.168.1.33, password and click on the OK button:

In the next window, set the checkboxes on the digital channels that should be added to the additional recorder. In our case, three HD-TVI cameras are used, which are connected to 1-3 channels on the main HiWatch DS-H104G recorder:

Cameras added to additional recorder:

What are the advantages of using an additional video recorder to solve the described problem?

  • Cost. An additional recorder will be cheaper than an HDM extension cable (at a distance of more than 50 m);
  • Camera control. If you use an extension cord, you will have only an image, and with the help of a video recorder, you can display the cameras on the full screen, enlarge the image;
  • Simplicity. There is no need to run additional coaxial cable from each HD-TVI camera. You are using the IP functions of Hikvision and HiWatch DVRs.

Webcams are cool. Indeed, there is no limit to what you can do with a webcam. Now the camera may not be as interesting as it used to be, but it is still one of the most useful devices I have. One thing that seems odd to me with webcams is the lack of flexibility in using it.

How can I make sure that I can see on my work what comes from my webcam regardless of what I am doing? What to do if I don’t like to sit in a video chat stupidly and stare at the chat client?

Not so long ago I came across the CamDesk program. This is a tiny open source application that offers a really simple solution to the webcam problems mentioned above. With CamDesk you can get a constant stream of data from any of your webcams into a customizable window, and no matter what you do, you can keep an eye on everything that happens in front of the webcam. The program can be used for any purpose: from tracking your cats and watching the front door to constantly broadcasting your image in video chat or recording video. Sumptuously!

Using CamDesk

If you have more than one webcam connected to your computer, then the first thing you need to do is select the one you want to use to continuously broadcast the video signal. Unfortunately, the camera cannot be changed inside CamDesk and there is no other option but to restart CamDesk every time you want to change the video source. Since it is a very small and fast application, restarting it shouldn’t cause too many headaches.

Now that you’ve selected a signal source, a video feed should appear on your desktop. It looks something like this:

After combing your hair (which I didn’t seem to be able to do), you can start a video chat or start a video recording, or just browse the web and see yourself at the same time if you want. You can move the video window by dragging it with the mouse and place it in a less visible place on the desktop. Right click on the video to access some additional options.

From the menu that opens, you can start and stop the video, switch to full screen mode, access advanced settings, and stop the CamDesk application. Each operation has its own hotkeys, if you prefer to use them, of course. Let’s see what additional settings are in store for us.

This is Bibi, my old cat, whom I am trying to observe with my other webcam. The advanced settings window, although a little unattractive, offers some useful settings. Here you can dock a video window and make it always on top of other windows, or un-dock and make it behave exactly like other windows. You can also resize the video image and choose it to your liking, and you can also change its transparency.

This last parameter will be interesting if you want to keep an eye on yourself or someone else and do something else at the same time and do not want the video image to cover something of value displayed on the screen. To do this, you can specify that the video image is translucent, and you will not lose sight of it.

If you have an external webcam, you can, no matter what you do on your computer, always keep in sight of the object you are watching. This way I can write this post and watch to see if my cat is awake.

He’s looking straight at me, isn’t he? As if it is part of the post I am reading.

How to choose a monitor?

To find the right CCTV monitor for your system and your needs, you need to take into account the following factors:

  • monitor matrix resolution;
  • diagonal;
  • update frequency;
  • power;
  • external interfaces;
  • heat dissipation;
  • degree of radiation.

An important feature of the monitor used is that it must have a composite signal input. Without this, connection is impossible.

The most important of these metrics are resolution and diagonal. The first determines how clear the image will be, the second affects the size of the resulting image. The optimal combination is HD resolution (1200×1600 pixels) and diagonal from 18 to 22 inches.

The choice of diagonal is also influenced by the number of video surveillance devices. After all, if there are many cameras, and the screen is small, this simply will not allow you to understand what is happening. According to the existing recommendations, the diagonal depends on the number of video cameras:

  • 1-2. 15 inches;
  • 3-4. 17 inches;
  • 5-9 chambers. 19-22 inches;
  • 10-16 cameras. 22-40 inches;
  • 17-20 cameras. 32 inches and more.

The clarity and quality of the image depend on the dot pitch. the minimum distance in millimeters between pixels of the same color. The lower this indicator, the clearer the resulting picture will be. Experts strongly advise against buying monitors with a pitch of less than 0.26 mm for monitoring purposes.

The flickering of the screen depends on the refresh rate, and, accordingly, how tired your eyes will be from viewing the picture. You should buy a monitor with a flicker frequency of 85-100 Hz. over, the larger the number, the lower the fatigue.

You also need to pay attention to the connection method. It is recommended to select screens with the maximum number of connection methods (HDMI, VGA, DVI).

If there is always a person in front of the screen watching what is happening, you should choose monitors with less radiation. And for reasons of economy, it is logical to buy a screen with the lowest power consumption.

Since the video surveillance screen is constantly on, you need to take care of overheating or, more precisely, its prevention. For this, it is recommended to purchase a screen with an external power supply. This will reduce the amount of heat inside and increase the lifespan of the device.

On a note! Can be used for video surveillance and the screen of an ordinary home TV. The main thing is that it is equipped with a composite connector via an RCA cable.

Installing CamDesk

CamDesk is an open source project that is still being developed by several independent developers. As such, it is magnificent in its simplicity, but only in some places it is incomplete. It is reported that CamDesk is available for Windows, Linux, Chrome and Android systems, but as for the last two implementations, they are still far from the end of the development stage, and even the developers themselves do not recommend downloading them.

If you are using a Linux system, when you download the tar archive, you will find installation instructions in it. With your permission, I will focus on the Windows version for now. To install CamDesk for Windows, you must have the.NET Framework 4 package installed. That’s all you really need to install CamDesk (assuming, of course, you have 1.17 Mb of free space on your hard disk).

CamDesk is portable and there is no installation process as such. Just unzip the files and run the EXE file. You are now ready to try some of the webcam’s features.!

CamDesk is a great little utility that you can use for almost anything you can think of. Here are just a few ideas on what can be done with such a tool. What could you use it for? Do you have great ideas? Share in the comments so we can do it too!

The sequence of installing a WEB-camera on a computer

In fact, there are more words than deeds here. To install a WEB-camera, you need to do TWO steps:

How to install a WEB-camera?

You promised your relatives a long time ago to make a video call, for example, Skype or Viber, instead of texting in Odnoklassniki. And finally, you bought a WEB-camera, brought it home, maybe even connected it to a computer, but it doesn’t work. And in general, how to install the WEB-camera correctly and on the first try? About this in order.

We connect the camera

WEB cameras are connected via USB.

WEB-camera is connected via USB interface

For example, let’s connect the Genius FaceCam 1005 webcam. Find the required connector on the case of the system unit, it can be on the front panel and on the back or on the end faces of the laptop and plug the camera cord into it.

READ  The screen on the monitor has moved to the right what to do

Let’s check maybe? has everything already worked? To do this, go, for example, to Skype, if it is installed. If you have not used this program yet, see how to install Skype.

If Skype is already installed, you need to go to the “Tools” menu and after “Settings”.

We select the item “Video settings” and lo and behold, our WEB-camera already shows the image.

As you can see, our camera is installed perfectly.

This means that it is already working and you can freely call friends and acquaintances.

But, if your camera is not visible in the list of Skype cameras, most likely the reason is related to the lack of a driver.

How to install the driver on a WEB-camera?

The delivery set, as in our case, always comes with a disk with drivers for the WEB-camera. Insert the disc into the drive.

Usually, there is always some proprietary program for working with the camera on the disk, but we still need a driver. It is usually called “Driver” or “Drivers” or “Camera Name Drivers”. In our case, it was named Genius Utility.

Disk menu with drivers for WEB-camera

Select and install as a regular program.

The camera driver is installed like any other program

If the camera did not work before, now it will work for sure.

By the way, as I said on the disc there is a program for working with the camera, here you can even curl up at the interlocutor or add unusual effects to yourself, turning, for example, into a fairytale hero :).

CrazyTalk Cam Suit PRO allows you to add different effects to the image Here, for example

The question of how to install a WEB-camera can be considered closed. Now you have set up the camera not only for yourself, but you can also help your friends in this.!

Picture

Customize the image in the video calling app. For camera settings in programs such as Skype, you need to go to a special section. It’s in “Tools”. “Settings”. “Camera Settings”.

In order to install and configure the camera, you need:

  • Place it in a place convenient for you, taking into account the installation method.
  • Check that the wires are long enough and that they are all connected.
  • Connect device to computer.
  • If there is a disk with drivers, then install them.
  • Check the operability of the camera in the “Device Manager”.
  • If this does not help. download drivers from the Internet.

Installing Drivers

Following the instructions, you installed the drivers and connected the webcam, but it does not work? Or are there no drivers at all? Not sure how to set up a webcam on your computer? You can solve this problem yourself by downloading and installing the necessary driver packages.

First you need to check for drivers. For this:

  • Go to Start, enter “Device Manager” there and click on the result that appears.
  • In the window that opens, find the item “USB Controllers” and click on it.
  • Find your device in the list and check it for an exclamation mark.

If there is this mark next to the device, then the drivers were not installed or were installed incorrectly. You can cope with this problem by installing them through the built-in installer or downloading from the Internet.

Download via built-in installer:

  • Right-click on the device and select “Properties”.
  • Go to the “Drivers” tab and click on the “Update” button.
  • Wait for the installation to finish and try to reconnect the webcam.

The likelihood that the built-in installer will be able to install the correct drivers the second time is small.

To improve efficiency, in the same menu, you can try to uninstall or roll back the driver version.

If even after that the webcam does not work, then you will have to install the drivers yourself. To do this, follow the algorithm:

  • Find out the device ID in its properties in the “Task Manager” or its name on the package.
  • Enter an ID or name in the search bar in your browser. You can sign the word: “Driver”.
  • Among the results obtained, find the manufacturer’s website or forum from which you can download the necessary drivers.
  • After downloading, run the installer and try to connect the device again.

For downloading, it is recommended to use links from the official sites of the company or verified forums. It is also important to enable antivirus, because instead of a driver, you can download a Trojan.

It is possible that the device is simply broken and all of the above methods will not help. In this case, you can hand it over under warranty, take it to the master, or, if the webcam is very cheap or old, just throw it away.

Installing and configuring a webcam on a computer

Distance no longer interferes with comfortable communication. We can communicate with loved ones on the other side of the world, using not only sound, but also video. For this, webcams are used.

How to install a webcam on a computer and configure it. this article will be discussed.

Connection

If the kit includes installation instructions, then find out from it what you need to do first: connect the device or install drivers, the disc with which may not be included in the kit. This happens when they are installed automatically.

The webcam is connected using a USB cable to the rear port of the computer. You shouldn’t plug it into the port on the front of the case, because it is used for devices that often have to be unplugged. The webcam is installed for a long time.

All wires from the webcam must be connected. This can be a microphone wire, a second USB, or an electrical plug. The last two are used to power the device and without connecting them, it will not work.

Accommodation

Cameras come with stands or clothespins. The first option involves installation on a table or shelf. The second allows you to attach the device to the monitor if it is thin enough. When installing a webcam, you need to make sure that you can be clearly seen. To do this, she must be directed at you and stand at some distance.

Optimal placement if it has a stand:

  • Under the monitor.
  • Side of the monitor.
  • On the shelf on the side, at eye level.

If instead of a stand it has grips, then attach the camera to the monitor from the side convenient for you. Remember that placement depends on the length of the USB cable. For this reason, placing the device very high or far will not work. If you want, buy a USB extension cable and increase the distance from the computer to the webcam.

You can check if you are clearly visible in the frame using the Skype program. Remember that how the other person sees you depends on the angle at which the lens is aimed at you. If he looks from below, then the chin seems more massive, if from above, then the forehead seems more massive.

Customization

The configuration is divided into changing the parameters of the device, which are convenient for the user, and solving problems with the connection. If the first type of setting is not so important, because the standard settings allow you to use the device, then you cannot do without the second.

Installation

Installing the camera includes connecting it to the USB port and placing it on the desktop.
