VIDEO SURVEILLANCE VIA USB CAMERA
The easiest and most affordable way to organize a video surveillance system. connect a USB camera to the 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 USB converter;
- Classic USB digital cameras (WEB-camera, “webcam”).
In the first case, special equipment is used. USB converter, which is a compact video recorder (video capture card with 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, as well as full compatibility with computers and laptops with Windows operating system. Main disadvantages. limited functionality and poor image quality in comparison with a full-fledged DVR.
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, IR illumination turns on automatically (there is a light sensor on the equipment case).
The main advantages of digital USB cameras. 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).
USB CAMERA Software
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.
The converter software is usually included in the package. Thus, the popular EasyCAP002 DVR converter model is designed to work with Super Viewer.
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.
- Webcamxp. one of the most popular programs. Main advantages. flexible settings, compatibility with almost all camera models, the ability to use a motion sensor to send alerts by email.
- Mobile Computer Control. built-in recording scheduler, motion detector, the ability to remotely control the computer via a mobile phone.
- Xeoma. does not require installation (can be launched from a memory card), support for all types of cameras, motion detection, alert mode.
- Ivideon Server. an interesting solution with the possibility of cloudy video surveillance. 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.
How to connect the CCTV CAMERA TO USB
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 image resolution. It should be borne in mind that saving video files in high resolution requires much more space on your hard drive.
After connecting the device, you need to install 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 any 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. yellow, audio. 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. For converters it is recommended to use the software included in the delivery.
- Comments pictures. the device is NOT recognized by the operating system. Decision. reinstall drivers.
- Camera works intermittently, image freezes, etc. Decision. check the quality of the USB connection. If an extension cord is used, it is necessary to check the camera’s performance 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.
When choosing a USB digital camera for video surveillance, it is recommended Pay attention to models from well-known manufacturers:
For video surveillance in the dark 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 you have 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 select 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:
- Streetwear, etc.
Given the limited functionality of systems based on USB cameras and converters, it is recommended to Pay attention to the more advanced IP video surveillance from a technical point of view.
But with low system requirements, this equipment. the best choice in terms of savings. You just need to connect a WEB-camera and install the appropriate software.

How to connect an action camera to a computer
If you do not remember your password, then enter your email and you will receive a login link. After authorization, enter your new password in the profile settings.
The photo shows a dome 2 MP IP-video camera with a wide-angle lens for rooms PD1-IP2-B2.1 v.9.4.1. with 2.1mm wide-angle lens, latest-generation processor and H.264 / H.264 / H. 265 / H.265 codec support
What is required to connect?
Let’s start as usual, from simple to complex. I propose this time to consider the nuances of the first steps of launching an IP video camera, namely. Power supply and connection of the IP camera to the computer.
To connect we need.
- The camcorder itself
- Power supply or PoE switch (optional)
- A piece of two-core cable of the required length and cross-section (for power supply)
- Power plug
- Category 5 LAN cable (twisted pair UTP Cat 5e)
- RJ-45 connectors
- PoE splitter (optional)
And also a small set of tools:
Crimpers (crimps) for mounting RJ-45 connectors on a LAN cable (yes, I know, you can use a screwdriver, you can, but you don’t need to =)), a screwdriver of the required size for mounting the power plug on a two-wire cable and connecting it to a power source, a stripping knife wires, free time, and of course desire, where can we go without it.
We will assume that the video camera is already installed in the required place and we just need to connect it.
IP camera connection via twisted pair
Connecting the IP Camera Cable
The first step is to prepare the cables for connecting the IP camera to the computer. Let’s start with the power supply, since IP video cameras are quite demanding on power supply and have a sufficiently high current consumption, it is advisable NOT to save on the power cable. As an option, you can take a twin-core SHVVP cable with a cross section of 0.75 sq. Mm. It is easy to install as it is flexible enough. But I’ll warn you right away: the shell is afraid of the sun’s rays, so it is not recommended to lay the cord outside the room without additional protection. A corrugated pipe can act as such, but only intended for outdoor installation, and a LAN cable can also be packed in it. Next, we connect the IP camera via twisted pair.
Poe cable pinout for IP camera
We take a knife in our hands and strip the insulation from one side of the cord. Then, since this cord has an individual color for each wire, the brown conductor is clamped into the terminals of the power plug marked “”, and the blue into the terminal marked “-“. Serial pinout of the cable for the IP camera will allow you to NOT make mistakes in the future when connecting the power supply of the IP camera and will help to avoid the so-called “polarity reversal”, which can be fatal for the video camera. Happened? Excellent!
While we put the cord aside and deal with the LAN cable, strip the outer sheath of the UTP 5e cable from one side to a distance of 2 cm. (It is possible more, not critical) and arrange, after straightening each one, the conductors in the following order from left to right:
- White brown
After that, cutting the conductors to a length of 1 cm and insert them, and without changing the color sequence, into the RJ 45 connector, placing it with the contact group up.
After that, we crimp the crimpers, leave the other side of the cable as it is.
Next, we insert the power and LAN connectors into the corresponding sockets of the previously installed video camera and pull the wires to the place where the switch or video recorder will be installed, well, or a personal computer, if it was decided to use it as a registration device. After connecting the cable of the IP camera, connect the power cable to the power source with correct polarity, it is important!
Crimps the RJ45 connector to the second side of the UTP cable according to the above method and connect it to the DVR, either to a personal computer directly, or using a switch if there are several video cameras.
After checking the polarity and correctness of the UTP cable crimping, you can turn on the power source to the 220 V network.
The installation work is over, we wipe the labor sweat from the brow =) and proceed to setting up.
Connecting an IP camera to a computer directly or through a switch
Initially, we need to enter the address of the video camera and the PC in the same subnet, and then there are two options. Option one. The computer was previously installed, it is included in the existing local network and possibly has access to the Internet. And the second option. The computer did not previously have a local network connection and was just installed. Let’s start connecting the IP camera to the computer from the second option, since it is the most simple. Let’s consider the setting using the example of the Windows 7 operating system (for later, that it is at hand =)).
The computer has no network connection
A modern PC or laptop has a network card, which allows you to connect an IP camera to a computer directly or through a switch. First of all, connect the video camera to the LAN interface of the network card, or connect the switch to the LAN, and connect the video cameras to the switch, if we have several.
After we have done this, a network connection icon should appear in the lower right corner of the screen.
Right-click on it and select “Network and Sharing Center”
In the window that appears, select “Change adapter parameters”.
Next, right-click on the “Local Area Connection” icon and select the “Properties” menu item, like this.
Then, click on “Internet Protocol version 4 and again, and what to do, click” Properties “.
And we see approximately the following depressing picture, which hints to us that the address for this PC, in general, is NOT assigned and there is an option to Get it automatically, which does not suit us a little, since there is actually nothing to give it out. Let’s correct this misunderstanding.
First of all, we put a kryzhik opposite “Use the following IP address”
And these fields become available for editing:
In which we, remembering that the video camera has a default address of 192.168.1.10, that is, it is located in the first subnet (as indicated by the penultimate digit of the address), we immediately enter the following values:
In the term of IP addresses, enter the value 192.168.1.2 (well, because the 2nd address is free for us, in principle, the last number can be any unoccupied address within the 1st subnet), something like this turns out:
Then we simply left-click on the “Subnet mask” field and we get this value (and it cannot but please in fact) automatically:
The item “Main gateway” remains, but at the moment we have interest in it, you can enter any address on the SIM, let’s say 192.168.1.1 and at the output we will have the following picture:
Click “OK” at the bottom of the window and consider that the network interface settings for this option are completed.
The computer has a network connection and IP addresses
But the first option is also possible, when the PC already has a connection to the local network and assigned IP addresses, and then we need to proceed as follows:
Exactly as described above, we get to the network adapter and right-click on the item “State”.
Then, press the button “information”.
And we see the following: here we are interested in the values I highlighted, you will have different ones, but the essence does not change from this, we rewrite them, for the best memory. This is a pencil.
Then we exit this menu by the above procedure (I will not repeat myself), we get to this window, which we have already seen.
It is more likely to be either the same as in the example, or some address will appear.
If all the items are available for editing in it and the address is already entered in them, then the connection of the IP surveillance camera to the computer is completed and you can not read further. If everything is as in the example, then proceed as follows: put the little boxes opposite “Use the following IP address” and “Use the following DNS server addresses”, and write in the values that we saved on a piece of paper. Four eights can be specified as an alternative DNS server. Done.
Next, we will make the settings, which are necessary regardless of whether the IP address, subnet masks and DNS servers have already been entered previously, or we have just done it ourselves.
In the same window, click on the “additional” button and in the window that appears, click “add”.
In the window that opens, enter a free address within the first subnet, for example, 192.168.1.3
The subnet mask will be registered automatically, it will be enough to name this field, after which we press the “Add” and “OK” buttons on all previous windows. Done.
These actions were necessary in order for the PC to be able to work in two subnets at the same time, which is necessary for further changing the IP address of the video camera and adding it to the software, which we will now deal with.
It’s time to download and install the software. Despite the fact that it comes with the equipment on a CD, I recommend downloading it from the official website www.Polyvision.Ru.
Firstly, the CD is already an anachronism today and the CD drive is not present everywhere, and secondly, the version available on it is probably outdated and why don’t we get hold of a fresh version.
Configuring the software when connecting an IP surveillance camera
So, go to the above link, select the software item, then Windows.
After that, opposite the “CMS” item, click “Details”.
Perhaps someone will have a question why exactly “CMS”, although there is also an alternative in the form of “VMS”?
It’s simple: This software was born first and why not give it the palm, and in general, it impresses me with the severity of the lines and the ascetic interface, and we will consider “VMS” somehow later.
So, despite the fact that there are more recent versions, we download the version from 7.03.16, because it is self-sufficient for Win 7 and does not require the installation of a plugin.
Then we start the installation.
Select the software distribution directory (you can leave it by default)
In the future, we press the Next button all the time. Until we see this window:
In which we press “Finish”, after which we receive an invitation to select the interface language of the installed software. Personally, I prefer Russian, but you are at your discretion.
And we look forward to clicking “OK”. Done, the software is installed and moreover, it is running. We should see this window
In it, we leave everything as it is, the only thing you can put a kryzhik in front of the “auto entrance” so as not to receive this invitation in the future and click “Enter”. If a standard firewall is running on the PC, we get this warning
I grant access and see the following
Click “OK”, in the lower right corner, select the menu item “System”.
Adding IP devices, assigning an address
So, in the lower right corner, select the “System” menu item.
And then, just above the “Device”.
Next, select the item “Add area”.
We arbitrarily call it and press “OK” again.
After that, click on the created area and go to the “Add device” menu item.
Where, in turn, we press “IP search” and we get approximately the same list of all video cameras and / or DVRs connected to this PC.
In your case, since we are configuring everything from scratch, there will be one or more devices with the address 192.168.1.10. If the device is equal, then click on it with the left button, after which the data should be overwritten in the lower area of the window.
If there are several devices, and they have an identical network address, then we need to assign any free individual address to each device. To do this, select one of the devices and click “Change”.
Then we assign an individual address, let’s say 192.168.1.11 for the second device, 192.168.1.12 for the third, etc. Do not forget to press the “Change” button after changing the address and so do the required number of times, Based on the total number of connected devices.
After that, we get a list of devices, each of which has a unique address. We just need to select one of the devices and click the “Add device” button, and this will be done for each new device.
Then click “OK” and consider that the procedure for adding is over.
Next, in the left column, double-click on adding a device to connect it and drag the drop-down video camera icon to the required area of the screen.
After that, an image from the selected device appears in this area. This is done for each device addition.
We examined the main points of connection. It seems to me at this stage it makes sense to stop, so as not to inflate the format of the narration.We will consider further settings in the next cycles.
Maxim Answer “Next, we insert the power and LAN connectors into the corresponding sockets of the previously installed video camera and pull the wires to the place where the switch or DVR will be installed, or a personal computer, if it was decided to use it as a registration device. After connecting the cable of the IP camera, connect the power cord to the power source with the correct polarity, it is important!
Crimps the RJ45 connector to the second side of the UTP cable according to the above method and connect it to the DVR, either directly to a personal computer, or using a switch if there are several video cameras. “
I’m certainly not “7 inches in the forehead”, but I understand something. Are you NOT afraid with this article to provoke a grand return of video cameras due to their failure due to crimping the video camera connectors under voltage? Of course, a sane person with experience with such equipment understands that any actions with the exposed parts of the prodniks are not allowed to be carried out without making sure that there is no voltage, but people are different.
How to connect an action camera to a computer
From time to time there is a need to “reset” data from a smartphone to a computer (and vice versa). Well, if the volumes are small, then they can be safely transferred, for example, via e-mail, file exchanger or the cloud. But this is completely unacceptable when you need to download an archive of photos, a collection of music or an entire season of a series. How to connect Honor to a computer and quickly “transfer” Necessary information?
The fastest way to transfer data. via the USB cable included with the smartphone. Of course, you can use cables from other devices (for example, cameras, players, etc.), but some of them sometimes have a different pinout, which is suitable only for charging the phone and no more.
We take the cable and connect it with one side to the smartphone, and the other. to the USB port of your computer (laptop). It is assumed that you already have a more or less modern version of the operating system (Windows 10 or 7) installed and you will not have to manually install additional drivers.
We unlock the phone and in the notification curtain, click on the appeared USB charging notification.
A list of possible connection options will open, in which, to work with the file system of the smartphone, select the “File transfer” item and proceed to work on the computer (in this case, the smartphone can be locked).
Working with smartphone files on PC
On the desktop of the computer or in the quick launch panel of the Start menu, click on the icon “My Computer” or “Explorer” and in the section “This computer” we are looking for a new device, the name of which, as a rule, corresponds to the name of the connected smartphone.
Click on it and go to the conditional list of disks that the mobile device contains. In the event that a microSD is installed in the smartphone, in addition to the “Internal memory” (device memory), there will also be an SD card (external memory).
Depending on your needs, we click on the required disk and work with it in the same way as with ordinary files and folders on a smartphone (copying, cutting, deleting files, creating folders).
For example, in order to upload photos from an Honor smartphone to a computer, you need to go to the “internal memory” (if the camera settings are not selected to record photos to a microSD card), go to the DCIM folder, select the Camera folder in it, and all photos and videos are already there captured by smartphone.
Select all (or just the files you need) and copy them to your computer after the files are copied to the PC. they can be deleted from the smartphone.
After the work with the file system of the smartphone is over, it can be disconnected from the computer without any additional actions. While connecting to a PC, the mobile device will continue to receive calls, messages and other information, that is, the connection will not affect the phone’s operation in any way.
How to connect a security camera to a computer
IP camera. a network device that transmits a video stream over the IP protocol. Unlike analogue, it broadcasts an image in digital format, which remains so until displayed on the monitor. The 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 installed on your computer special software that comes with the camcorder.
Step 1: Camera setup
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, start 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 term “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”.
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 addresses of each in accordance with the subnet data (via the web interface).
Step 2: Viewing the image
After the camera is connected and configured, we 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 a 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.
Go to 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 will NOT 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. This is a software for WEB and IP cameras that can be installed on Axis, Hikvision and others.
Create a new configuration file and click “Next” to proceed to the next step.
Log in with your Ivideon account. Specify email address, camera locations (from the dropdown list).
The automatic search for cameras and second 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. Enter the equipment parameters (manufacturer, model, IP, username, password) here. 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 IP camera setup. 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. universal software for managing IP equipment and creating a video surveillance system. Allows you to view the 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 via 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. Using a USB cable 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.
Click on the “Recording” tab. Allow or block 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 install special software on your computer.
Why can’t I see my Xiaomi phone when I connect my PC
At a time when more and more choices appear in users of various gadgets, the number of problems, respectively, increases in direct proportion. Today we will try to understand this issue. how to connect Xiaomi to a computer and identify the main reasons why the computer does not see the phone. The fact is that the user is often worried about this problem, but the reasons for its occurrence may be different. To solve it, you may need third-party software or even a factory reset. So we recommend that you first read this article to the end, and only after that make a decision on what to do if the computer does not see Xiaomi.
- Main reasons
- How to fix connection problems
- Download driver
- Enable debug mode
- What to do if the phone connects in camera mode
- complex methods
- How to return connection settings
Below is a basic list of reasons why your MIUI smartphone does NOT connect to your computer:
- Drivers not installed on PC.
- Non-original USB cable.
- The phone was connected incorrectly.
- System problems or other causes.
Of course, this is NOT a complete list of reasons, since they can be very diverse, and it will be difficult to fit them into one article.
How to fix connection problems
When you connect your Xiaomi Redmi or Mi to your PC, several processes are launched at the same time, and they do not always work as they should. If, for example, your computer is NOT able to automatically find and install drivers for a smartphone, then the gadget on MIUI will not function normally. To begin with, it is important to know that you should only connect through the original USB cable (fake). If so, then the problem is not with him. After that, try connecting your Xiaomi phone to other USB ports (note that there are also such connectors on the back of the system unit).
To install the drivers, just download, unzip and install the following 2 archives: drivers for MediaTek (19 Mb) and drivers for Qualcomm (17 Mb). If you have Windows 8 or higher, before that you need to disable the driver digital signature verification and restart the PC. A little later, we will describe another way to install the driver.
Enable debug mode
Installing drivers on MIUI is as easy as shelling pears, but it also happens that this method did NOT help to solve the problem. In the second option, everything is also very simple. To implement it, go to Settings on your smartphone. Additionally. for developers. USB debugging and enable this function.
It often happens that at the moment of connecting a smartphone to a PC, users see a menu on the monitor that provides an opportunity to select the type of connection. We need an MTP type connection, which involves connecting a computer to a smartphone as a multimedia device. In addition, in the phone dialing menu, you can enter this combination: ###, which brings up the same menu. The menu itself looks almost the same on all devices, be it Xiaomi Redmi Note 3, Redmi 3 Pro or Xiaomi Redmi Note 2.
What to do if the phone connects in camera mode
In addition to the two above, there is also a third option, which we have highlighted separately due to its non-standardness. If your Mi connects to the PC only as a camera, and not as a storage device, then you can try to transfer the files you need to the “Photos” folder on the phone, and then distribute them to sections through the file manager. But this method is suitable for the lazy. if there is no desire to delve into the problem and make some efforts to solve it.
Also, pirated software or “left” MIUI firmware installed on the phone can be an obstacle, but we will NOT delve into this now. We would like to offer you some more complex options, if the PC did not see any devices connected to it.
If simple ways to solve the problem did not help you, and the PC still does not see the smartphone, we suggest you use a couple of new tips.
- Through the terminal. To do this, go to the Play Market and download the Android Terminal E application. Install it, then Connect your smartphone to the computer, thereby gaining access to the device in USB storage mode. After that, write “su” in the application (this is how super-user rights are enabled) and Confirm your choice. Then we enter another command: setprop persist.Sys.USB.Config mass_storage, adb and press the enter button (Enter). At the end, we write Reboot, thus rebooting the smartphone.
- Some users who want to log into the phone via MTP connect in the same way, Changing only one phrase in the last command, Replacing “mass_storage” with “mtp”.
If you remember smartphones such as Xiaomi Mi Max or Redmi Note 3 Pro, then there were no such problems with them, therefore it is unusual that they appeared with just the third Redmi smartphones. The Note 2 didn’t have similar problems either. But oh well, these are already the problems of the developers, and We must solve the problem with the connection.
How to return connection settings
If for some reason your connection settings have disappeared and you want to restore access to them. no problem. To do this, there is a program called QCustomShortcut (100 Kb) (it is not in the play market. Download it from this link). I downloaded and installed the program, run it. There will be several fields, in the second field (Package) select com.Android.Settings in the Class field. com.Android.Settings.Usbsettings. Click on the Create Shortcut button and enjoy the result.
Now you get full access to all connection settings. By the way, if you go back to the same drivers, we also recommend installing the Mi Phone Manager or Mi PC Suite (38 MB). with her, you will forever resolve the issue of their absence. Connect the smartphone with the already installed program, open the right mouse button on the window “My Computer” and go to the Task Manager. Find the unidentified device there. smartphone and cable. and then click on “Update” in the “Driver” section and specify the path in the MiPhone Manager folder to main / Driver.
