Accessing the camera of an Android device in a browser window

By entering IP in the browser window on the computer. displayed in the column “Browser IP Cam Access” in the Android application, we will get access to the camera of the mobile device. For this, we do not need to install the DroidCam Client program on Windows or Linux. Just enter the IP address specified in the Android application into the address bar of the browser on the computer. And we can test the connection. Well, or even temporarily use a mobile device as a surveillance camera, installing it in the right room to shoot the desired object, which we can observe on the monitor screen.

connecting, camera

FPS limiting functions are available to us in the browser window. saving frames as images, activating autofocus, activating the flash and zooming. By the way, this is also a demonstration of some of the setting capabilities when using the camera at the system level as part of the functionality of a paid Android application.

But so that the camera of an Android device is displayed not only in the browser window, but is defined at the system level as a peripheral device, i.e. as a webcam, you need to install the DroidCam Client program in the operating system environment.

About the software

So, DroidCam Wireless Webcam is software for using the camera of an Android gadget on a computer as a peripheral device. If we, for example, do not have a webcam on our PC, we can use our phone or tablet. Another example: the built-in laptop camera may not work, or maybe we just want to use a higher quality image than the minimum that is usually offered by the front cameras of portable devices. The software includes an Android application and an operating system driver that connects the gadget’s camera as a computer peripheral. Such a driver exists as a DroidCam Client program for Windows and Linux.

The DroidCam Wireless Webcam software is remarkable, firstly, because it is free in terms of using basic functions, and secondly, two options for establishing a connection with a computer. via local network (both Wi-FI and wired) and via USB cable. Using the free version of the Android app. DroidCam Wireless Webcam, we get the opportunity to simply connect the camera of an Android gadget without any of its settings. In particular, even without the choice of front and rear cameras. Only the rear camera will be connected, and it will be with a quality of no more than 480p.

When using the paid version of the application, and this is a separate application, and it is called DroidCamX Wireless Webcam Pro, we will be able to make some settings in the camera’s operation. zoom, rotate the image, adjust the brightness and contrast. Video in 720p quality will be available to us. We will also be able to turn on a flashlight for illumination, save frames from the camera in JPG format. adjust FPS and enable continuous focus.

Both applications can run in the background, using minimal battery power. And both applications, in addition to the camera of the Android device, allow you to use its microphone.

Links for installing Android applications on Google Play can be obtained on the DroidCam Wireless Webcam website:

Here we can also download the program for the computer DroidCam Client.

In the DroidCam Wireless Webcam application, we will see the data for connecting to the computer. This is the IP address and port for connecting the camera of the gadget via the local network and via USB. And this IP address to access the camera of the gadget in the browser window on the computer.

USB connection

To connect the camera of an Android device via USB. on the device itself, activate USB debugging in the settings. Next, on the computer in the DroidCam Client program, switch to the tab with the USB icon and click “Start”.

Wireless connection

To establish a wireless connection of a smartphone or tablet camera. a local network connection, launch the Android application. On the computer, run the DroidCam Client program. And in its window, enter the IP address displayed in the Android application. If you need to additionally use the microphone of a mobile device, put a check mark “Audio”. And we press “Start”.

How to use the camera of an Android device as a computer webcam for Skype and Viber communication

Buying a webcam to use on a computer can be a completely unnecessary waste if we have an Android device with a built-in camera. We can use the camera of a smartphone or tablet on a computer when communicating via Skype. in Viber and similar type of Internet messengers, as well as when working with other programs that require a camera connection. To do this, you need to install a special application on your Android gadget.

One of those that allows the camera to function as a computer peripheral. And in the operating system environment, you need to implement the driver for such an application. One of these is the DroidCam Wireless Webcam. Let’s look at how to use the camera of an Android device as a computer webcam.

Camera control and use

After connecting the camera, we will see its image in the DroidCam Client window. And in the options panel at the bottom, we can configure it if a paid application is used on the mobile device. When using the free application, the settings will not be available to us. Then we simply turn off the DroidCam Client program and can use it in Internet messengers and other programs. To turn off the camera in the DroidCam Client window, click “Stop”.

We can also stop the camera connection in the Android application.

In Skype, Viber and similar Internet messengers, you usually do not need to make any settings. The camera should be defined by them by default. But if the computer already has another camera, for example, a native front-facing laptop, the camera of the Android device must be set active in the settings of each of the programs. In Skype, we need to go to settings.

And in the “Sound and Video” section, specify the DroidCam Source 1 device as the camera.

In Viber, we also go to the settings and in the “Audio and Video” section in the “Video” block we expose the DroidCam Source 1 device.

In other Internet messengers, we do the same. If, in addition to the camera of an Android gadget, you need to use its microphone instead of the default one, select it as the active device in the same sections of the Skype and Viber settings.

    About the software

    So, DroidCam Wireless Webcam is software for using the camera of an Android gadget on a computer as a peripheral device. If we, for example, do not have a webcam on our PC, we can use our phone or tablet. Another example: the built-in laptop camera may not work, or maybe we just want to use a higher quality image than the minimum that is usually offered by the front cameras of portable devices.

    Links for installing Android applications on Google Play can be obtained on the DroidCam Wireless Webcam website:

    Here we can also download the program for the computer DroidCam Client.

    In the DroidCam Wireless Webcam application, we will see the data for connecting to the computer. This is the IP address and port for connecting the camera of the gadget via the local network and via USB. And this IP address to access the camera of the gadget in the browser window on the computer.

    What to do if DroidCam does not work in the browser

    Often, users are faced with a problem when a smartphone works great as a webcam in Skype, but in online chats, any browser shows only a black window. In some cases, warnings even appear. For example, in chat roulette it is forbidden to use programs such as DroidCam, SplitCam, ManyCam and the like.

    However, with proper application configuration, this limitation can be easily circumvented. It is enough to follow these steps:

    • Install the ManyCam program on your computer or laptop.
    • Open the “Settings” menu, where in the “General” tab, in the appropriate line, write any name for your virtual WEB-camera, other than ManyCam.
    • Launch the DroidCam application in the mobile and the client on the PC, connect using any of the methods described above.
    • In ManyCam, in the “Video” tab, select one of the DroidCam virtual cameras, which will be broadcast in the video chat. To do this, in one of the square windows on the right, click on the serial number of the camera (upper right corner), move the mouse cursor over the “Cameras” item and find what you need in the drop-down list. The image from the camera with the LIFE icon in the upper left corner of the window will be shown in the Chat Roulette.
    • All that remains is to go to the video chat site in any browser except Chrome. Everything works fine in Firefox, Opera and Yandex.

    As you can see in the above screenshot, the image in the ManyCam program is shown mirrored relative to the video in the DroidCam program window. However, already in the Chat Roulette itself, everything is displayed as needed. If necessary, the paid version of the DroidCamX program allows you to rotate or mirror the picture with one click of a button. If these buttons are not active in the application, it is enough to turn the smartphone itself in the desired direction.

    There are also alternative programs that allow you to use your smartphone as a webcam. They usually work in a similar way. If it is necessary to organize remote monitoring using a phone, then this can be done using the equally popular IP Webcam application.

    Phone as a webcam

    Buying a webcam for a computer is not always necessary for smartphone owners. Modern technologies allow their owners to simply use the phone as a WEB-camera. However, before using the phone as a WEB-camera for a computer, it is worth exploring possible ways to use the gadget.

    When and why you need to use your phone as a WEB-camera?

    Conducting a WEB-camera through the phone is always possible, especially if the phone has a good camera, which will improve the quality and ease of use.

    As a standard, smartphone owners think about how to connect a WEB-camera to a phone, if necessary:

    • Replacement of a standard WEB-camera in case of its breakdown;
    • Urgently conduct a video call or video conference in the absence of a normal WEB-camera;
    • Use a phone instead of a WEB-camera to set up remote monitoring;
    • Create an additional WEB-camera for video or online broadcasting.

    You can connect to the phone’s WEB-camera regardless of the reason why the owner of the gadget plans to use it in many ways. However, keep in mind that for such a use of a smartphone, it must support and transmit the clearest picture and sound.

    The easiest way to make a WEB-camera out of a phone is to use a USB connection to a computer. Almost all devices support this way of using a smartphone.

    Before connecting the WEB-camera to an Android phone or iphone, a special application must be installed on the device that sets up the connection between it and the computer. You can select it in Google Play or App Store, respectively. You also need to install such an application on a PC in order for it to accept the gadget.

    READ  How to display video on a WEB-camera

    The use of the program on the phone as a WEB-camera is based on the synchronization of the device via a USB cable. However, for a mobile smartphone and the convenience of moving it, you can also use Bluetooth.

    Before downloading a WEB-camera to your phone, keep in mind that the quality of the picture and sound displayed on the screen from the device will also depend on the application. Common applications for this are DroidCam and USB Webcam.

    If the variant of connecting the smartphone with the previous methods is not suitable, for this variant it is necessary to have a Wi-Fi network. And also for the phone to work as a WEB-camera via Wi-Fi, you first need to install the DroidCam Wireless Webcam application on the device. It is downloaded additionally to the receiving device. a computer.

    After starting the programs, follow the steps:

    • Connect to a Wi-Fi network on your phone.
    • When opening the application on a computer, select the option “connect via Wi-Fi”.
    • A special window will open on the computer, in which you need to enter the code from the phone. To do this, open the “Wi-Fi IP” item on the gadget and rewrite the number.
    • Check the correctness of the connection on the PC (for this, audio and video must be ticked).
    • Click “Start”.

    After completing the above measures, you can use the phone as a WEB-camera. However, keep in mind that the quality of the connection and video also depends on the application that you have chosen to use on the gadget. Because of this, it is better to pay attention to proven programs.

    Using your smartphone as a remote surveillance

    As a video surveillance, the phone’s WEB camera can also work if you connect it correctly. This method does not require a Wi-Fi connection (only for installing applications) or a USB connection. You can watch the video signal from your smartphone from the other end of the city.

    Before connecting a WEB-camera via a phone, you need to install a special application on the gadget. IP Webcam. Additionally, download the adapter to the PC from the developer’s official website.

    Further work is carried out in the application itself:

    • Launch the camera for broadcasting in the program.
    • Choose the quality and other video capture options (orientation, location, color balance, flash, etc.).
    • Click “start streaming”.

    You can view the running broadcast in three ways: in Skype, through the browser or through the VLC video player. Keep in mind that the quality in the video broadcast may be slightly worse than the selected parameters, therefore it is recommended to pre-assign the highest transmission quality.

    To view the broadcast in a browser, you need to specify the device port and IP address in the search bar, which can be found from the source application.

    How to use your phone on Skype

    In Skype, the device can also replace the WEB-camera, if it is configured correctly for this. To do this, you must first download the adapter for broadcasting from the official website of the developer.

    Then open the adapter and type in the IP address of the device, adding “/ videofeed” to it. Set the appropriate resolution that is suitable for the gadget to work, select “apply”.

    After that, open Skype and in the settings instead of the WEB-camera, select. MJPEG Camera. After that, the signal to the PC screen should go from the mobile device.

    You can use a phone as a WEB-camera in different ways, which determines the speed of image and sound transmission, its quality and convenience for the user. You can choose how to use the phone as a WEB-camera based on the conditions of the room and the capabilities of the gadget. So you can replace a special device if it is missing or broken.

    Checking and disabling the webcam

    To disable the webcam, you need to follow the following path: Start. Settings. Privacy. Camera. Before us there is a functionality that allows you to activate and deactivate it. If you have any problems with the performance of the camera, then proceed as follows:

    • Go to Start. Settings. System;
    • In the window that appears, select the “About System” item, it will be on the left. We pay attention to the right block, where you need to find and select “Device Manager”;
    • Find the column “Image processing devices”, expand the list and right-click on the name of the webcam. Here you can disable and start it, update drivers and view properties.

    The quality of video communication is affected by the characteristics of the available graphics equipment. If you have a fast Internet connection, but at the same time the picture has a lot of noise, then this cannot be influenced in any way. The only way to solve the problem is to buy a new camera.

    Probable driver problems

    If in the “Device Manager” you did not find your WEB-camera or it is designated as unrecognized equipment, then for its normal operation you will need to download the driver. This can be done using the capabilities of Windows 10. the system will find them in its database and automatically download them to your computer. To do this, right-click on the hardware and select “Update driver”. We select the automatic search method if you have not previously downloaded the drivers to your computer. Then they will be automatically downloaded from the Internet and installed on your computer.
    There is another way. visit the device manufacturer’s website and download the current version of the drivers from there.

    Camera setup in Windows 10

    Microsoft in Windows 10 introduced a special utility through which video communication is carried out. But a novice user often has difficulty turning on the webcam for the first time, not knowing where to find it and how to install the drivers if they are not installed automatically.

    • Open “Start”, where we go to the general list of applications and look for the “Camera” service;
    • The monitor displays detailed information about the application. If the webcam is configured correctly, then it is activated and you will see the image from it.

    As you can see, turning on the webcam is not difficult, right after this action you can use all its capabilities.

    Connecting and configuring an external camera

    An external camera is a separate device that connects to the USB port of a computer. The design and shape of the device can vary greatly, which primarily depends on the manufacturer. Many models have a built-in microphone, thereby avoiding unnecessary financial costs. For connection, it is recommended to use active extension cables, which will provide the WEB-camera with additional power, which has a positive effect on the signal quality. Using an active cable, you can position the camera at a distance of 10 meters from the computer, while when using a passive cable, the limit is set to 5 meters.

    The package with the camera includes a disk containing all the drivers and software from the manufacturer necessary for operation. To configure the camera, connect it via the USB port, turn it on if the corresponding key is provided on the case, install the disk into the drive and load the driver. With the help of software from the manufacturer, you can adjust the microphone volume, enable and disable the camera. In most cases, you don’t even need to install drivers. the system finds them automatically after connecting the device.

    Opening access to applications for working with the camera

    Often the camera does not work in some programs, which may be limited access. It is very easy to remove it, for this we do the following:

    • Go to “Parameters”;
    • Section “Confidentiality”;
    • We select the applications that need to be granted access and move the switch opposite them to the “On” position.

    We hope that our text and screenshots helped you connect and configure your WEB-camera correctly.

    USE ANY CAMERA AS A WEBCAM (no camlink required)

    Webcam device (page 1 of 2)

    A digital webcam is a network device that consists of a video camera (CCD), a compression processor, and an embedded web server. Typically, a webcam is used as a device for organizing video filming, video conferencing or video surveillance and transmitting video over a LAN / WAN / Internet network. For the webcam to work on the network, no special devices and a personal computer are required. Depending on the settings, access to the video image received by the webcam can be open to all network users or only authorized users.

    Connecting and installing a webcam

    Typically, a webcam is connected to the Internet via the 10BaseT / 100BaseTX / 1000BaseTX Ethernet port or using a modem via a serial port. After the webcam is physically connected to the network, it is assigned an IP address. often than not, a webcam does not have a default IP address; it is installed either using the appropriate function of a standard web browser, or using a DOS command that uses the serial number of the webcam assigned to it by the manufacturer for identification. In addition, manufacturers are developing special programs for webcams that greatly simplify the procedure for assigning an IP address to a webcam (for example, the IP Installer from AXIS Communications). With built-in software for web server, FTP server, FTP client, e-mail client, etc., the webcam connects directly to the LAN / WAN / Internet network and works as a standalone network device in it. This distinguishes webcams from other digital cameras, which require a mandatory connection to a personal computer via USB or LPT port. In addition, webcams can support custom scripts and JAVA applets.

    READ  Connect the WEB-camera to the router via USB

    To install a webcam outdoors or indoors, many manufacturers provide special fasteners in the design of the camera body, designed for installation on walls, ceilings, brackets and rotary devices. Some webcams have built-in PTZ devices for mounting on a horizontal or vertical surface.

    The device and principle of operation of the webcam

    A modern webcam is a digital device that captures video, converts an analog video signal to digital, compresses a digital video signal and transfers video over a computer network. Therefore, the following components are included in the webcam:

    video compression (compression) unit,

    central processing unit and embedded web server,

    As a photodetector, most webcams use CCD (CCD, CCD. Charge Coupled Device). a rectangular light-sensitive semiconductor plate with an aspect ratio of 3: 4, which converts the incident light into an electrical signal. The CCD consists of a large number of light-sensitive cells. In order to increase the light sensitivity of the CCD, a structure is often formed that creates a microlens in front of each of the cells. The technical parameters of a webcam usually indicate the format of the CCD matrix (the length of the diagonal of the matrix in inches), the number of effective pixels, the type of scan (non-interlaced or interlaced) and the sensitivity.

    Lens. This is a lens system designed to project an image of an object of observation onto the light-sensitive element of a webcam. The lens is an integral part of the webcam, therefore, the quality of the video image received by the webcam depends on the correct choice and installation. Quite often, a webcam comes with a lens. Lenses are characterized by a number of important parameters, such as focal length, aperture (F), depth of field, mount type (C, CS), format.

    Optical infrared cut-off filters, that are installed in webcams are optically accurate plane-parallel plates mounted on top of the CCD. They work as optical low-pass filters with a cutoff frequency of about 700 nm, near red. They cut off the infrared component of light waves, ensuring the correct color reproduction of the webcam. However, many black-and-white webcams do not have such filters installed, so monochrome webcams have a higher sensitivity.

    Video capture card Webcams (digitizing unit) convert the analog electrical signal generated by the CCD into digital format. The signal conversion process consists of three stages:

    Sampling. reading the amplitude of the electrical signal at regular intervals (period). This stage of signal conversion is characterized by a sampling rate.

    Quantization. it is the process of digitizing sampling results. The change in the level of the electrical signal over the sampling period is represented in the form of a codeword of 8, 10 or 12 bits, which give respectively 256, 1024 and 4096 quantization levels. The accuracy of the digital representation of the signal depends on the number of quantization levels.

    Coding. In addition to the information about the change in the signal level obtained at the previous stage, during the encoding process, bits are formed that indicate the end of the sync pulse and the beginning of a new frame, as well as additional bits of error protection.

    Compression unit webcams compress the digitized video signal into one of the compression formats (JPEG, MJPEG, MPEG-1/2/4, Wavelet). Compression reduces the size of the video frame. This is necessary for storing and transmitting video images over the network. If the local network to which the webcam is connected has limited bandwidth, then in order to avoid overflowing network traffic, it is advisable to reduce the amount of information transmitted by reducing either the frame rate over the network or the frame resolution. Most of the compression formats that webcams use provide a reasonable compromise between these two ways to solve the problem of transmitting video over a network. The currently known compression formats allow you to get a digitized stream with a bandwidth of 64 Kb. 2 Mb (with this bandwidth, video streams can work in parallel with other streams in networks).

    Compression of video images in a webcam can be represented both by hardware and software. The software implementation of compression is cheaper, however, due to the high computational capacity of the compression algorithms, it is ineffective, especially when you need to view video from a webcam online. Therefore, most of the leading manufacturers produce webcams with hardware compression. For example, every network camera from AXIS Communications is equipped with an ARTPEC compression processor that performs high-speed video compression in JPEG / MJPEG format.

    CPU is the computing core of the webcam. It carries out operations for the output of digitized and compressed video image, and is also responsible for performing the functions of an embedded web server and a control program for webcams.

    Ethernet interface serves to connect the webcam to a 10/100 Mbps Ethernet network.

    For networking, the webcam may have serial port to connect a modem and work in dial-up mode in the absence of a local network. The serial port can also connect peripheral equipment to the webcam.

    Flash memory card allows you to update webcam control programs and store custom HTML pages.

    RAM serves to store temporary data that is generated during the execution of control programs and user scripts. Many internet cameras have a so-called video buffer. This is the portion of RAM reserved for recording and temporarily storing video footage captured by the webcam. The information in the video buffer is updated cyclically, i.e. the new frame is written over the oldest one. This function is necessary if the webcam performs video surveillance, since it allows you to restore the events preceding and following the alarm from the security sensors connected to the webcam.

    Alarm inputs / outputs serve to connect alarm sensors to the webcam. When one of the sensors is triggered, an alarm is generated, as a result of which the webcam processor assembles a set of frames recorded in the video buffer before, after and at the time of the alarm. This set of frames can be sent to a specified e-mail address or via FTP.

    Additional features and functions of the webcam

    Motion Detector. This is a software module, the main task of which is to detect web cameras moving in the field of view at a video surveillance object. The motion detector not only detects movement in the image field, but also determines the size of the object and the speed of its movement. Depending on the tasks of video surveillance, the webcam motion detector is configured to detect the movement of objects with the utmost minimization of false alarms (filtering noise), and flexible logic for processing alarms is set (alarm recording, integration with other security equipment).

    Audio transmission over the network, in most cases, it is carried out by connecting an additional audio module to the webcam. For example, the company AXIS Communications to expand the functionality of webcams releases a special audio module AXIS 2191, which is compatible with most AXIS webcams.
