Connecting with CameraFI

To work with a WEB camera via CameraFI, just connect the camera to your smartphone or tablet and launch the application. In the window that appears, allow the application to access the items it will ask for. After that, you can already use the camera. At the same time, it should be borne in mind that when setting the resolution in the settings more than the camera can give, the image may disappear.

The CameraFi app has four main benefits:

Some applications for connecting cameras require Root access, which removes the warranty from the phone, and improper use of it can lead to critical errors of the Android operating system.

  • Connection of both wireless and USB cameras

The application works with a wide range of cameras connected via USB OTG cable. It also allows you to connect cameras through other connectors; there is a corresponding adapter.

  • Support for a large number of cameras
connect, action, camera, phone

CameraFI is compatible with a huge variety of cameras from almost any manufacturer. The application works with action cameras, professional photo and video cameras, WEB cameras and camcorders.

The application supports high data transfer rates. Transfer can be done wirelessly at speeds up to 30 frames per second at FullHD resolution.

There is also a Russian-language version. The app itself is constantly being updated to support more and more new cameras and recording devices. Latest versions also work well with drone cameras, medical cameras and built-in action cameras.

CameraFi app has both free and paid version of CameraFi Pro.

UsbWeb カ メ ラ

UsbWeb app カ メ ラ is another way to connect an external USB camera to a smartphone. It also has a free and PRO version. You can download UsbWeb カ メ ラ in the Google Play Store.

The application itself has a simple interface and not as wide functionality as CameraFi, but at the same time it has wide compatibility with cameras from different manufacturers.

The application allows you to take photos and record videos in different resolutions. Camera fully configurable via smartphone.

To connect an external USB camera via UsbWeb カ メ ラ follow the instructions:

  • Connect camera with smartphone or tablet via OTG cable.
  • Run the app, go to settings and run connection diagnostics.
  • As required by the application, disconnect the camera from the smartphone and click OK.
  • When prompted by the app, connect the camera to your smartphone and click OK.
  • Then the camera will connect to the application, which will take up to 20 seconds.
  • After that, the application will ask you for permission to transfer data about the camera to the server. Here it is better to choose yes, since it is on the basis of such data that the base of video cameras and methods of connection with them is formed. All this helps to improve the application.
  • After that, you can use the camera. If the application does not detect it, try again.
  • In case of connection problems, select Stock in the USB Host Diagnostics window.

Branded Webcam Applications

For broader functionality and use of camera capabilities, it is best to choose applications from camera manufacturers. For example, there are now apps from GoPro and Yi Action Camera. Such applications make it possible to simplify work with cameras at times. They also make it possible to use Wi-Fi wireless connection.

Problems connecting the camera via USB

The most common connection problem is that the smartphone simply does not see the camera or does not recognize it correctly. Stickmount app is suitable for solving this problem. It allows the system to correctly identify the device and connect to it. The application itself for correct operation requires superuser rights on the smartphone.

Stickmount analyzes the connected device and allows it to be recognized as a USB camera. In addition to the camera, the application allows you to work with drives and other devices connected via a USB interface.

USB camera connection

CameraFi

The most user-friendly and reliable connectivity app is CameraFi. It now has over a million downloads and is generally a good grade for an app of this kind.

In addition, the developers approached the project thoroughly and made a whole site dedicated to it. The site itself is in English, but contains all explanatory materials on the application and cameras.

Return to the Xistore pages for helpful tips and instructions.!

Connectors, connection

Two connectors are hidden under the flap on the back of the camera. microHDMI and microUSB, as well as a slot for a microSD memory card. Wi-Fi is available to connect to Android devices.

Functionality, video recording, photo

At the heart of the camera is a 16-megapixel Sony Exmor R BSI CMOS sensor with a fixed f / 2.8 aperture. The maximum recording resolution is 1920 × 1080 pixels at 60 frames / sec, and recording at 240 frames / sec is available in 848 × 480 pixels (but who needs that !?). Photo resolution. 4608 × 3456 pixels.

At its cost, Xiaomi Yi demonstrates good results, and in some moments even approaches the GoPro Hero3 (excluding 4K support in the Black version). In good lighting, the picture both in the photo and in the video comes out wonderful.

But the microphone is mediocre and almost always only records noise.
In the video below you can evaluate the capabilities of the Xiaomi Yi camera in comparison with the GoPro Hero3 Black Edition in different situations.

Xiaomi Yi vs GoPro Hero3 Black Edition recording quality comparison

Quality comparison

Appearance, quality of materials

Let’s not beat around the bush. outwardly, the Xiaomi Yi Action Camera looks like a well-copied GoPro Hero, only without a monochrome display. Some elements are swapped, but it’s still the same monoblock rectangular form factor.

On the front there is a lens, a button for switching on and switching modes with indication. On the back side, under the caps, the battery, connectors and a microSD slot are hidden. At the bottom there is a tripod thread and a notch, apparently for accessories. GoPro has no threads on the camera itself, only on the boxes. The right end has assembled the Wi-Fi power button and the corresponding indicator.

The camera is made of matte plastic interspersed with gloss, the back is completely matte plastic. The device looks bright in shades of green and yellow, and white cameras are also available for sale. The acid chamber is more attractive to me. The difference from the GoPro Hero3 is that the American camera uses soft-touch plastic, while here it is the usual matte one. The assembly is good, sometimes only the battery cover could come out of the grooves by a millimeter, otherwise there are no complaints.

Xiaomi Yi Action Camera Review

Autonomy

The 1010 mAh battery is capable of withstanding about an hour of filming at 1080p / 30fps. Battery charging time is 1.5 hours. For on-site filming, it’s best to have a couple of extra batteries

Equipment

The package contains a classic of the genre from Xiaomi, a minimalistic box with only one Yi inscription and technical characteristics on the back. Inside is the camera itself, a monopod, a cable for charging and connecting to a computer, and documentation.

It should be noted that the monopod is included in the Travel Edition package, but it is not in the standard Standard Edition package. Additionally, there are boxes, mounts and other accessories on sale.

social networks:

American success in technology haunts Chinese manufacturers. Xiaomi and Meizu smartphones are already competing on equal terms with eminent competitors, but there are also uncovered areas. For example, the American GoPro reigns supreme in miniature action cameras ideal for shooting active sports. Well, nothing, you can fight this. thought Xiaomi, and presented their views on such devices. Ladies and gentlemen, welcome. Xiaomi Yi.

Control

There are only three buttons on Xiaomi Yi. power on, shutter release and Wi-Fi activation. Without connecting to a portable device, you can only switch between photo and video modes. All settings and advanced features become available after installing a branded application from Xiaomi.

I didn’t manage to download the.APK file from the official website, but the w3bsit3-dns.com forum helped with downloading the russified application. The latter is a copy of the GoPro app with its own design and good functionality.

It was not difficult to connect to the smartphone, but I still did not understand the principle of the Wi-Fi button. The indicator lights up in absolutely different sequences, whether it is a single keystroke or holding it for a few seconds, in general, the button has its own atmosphere. GoPro works the same way, but everything is clear there.

Design, technical characteristics

Also, the company is in no hurry to outstrip other manufacturers of action cameras with the composition of the package. She, completeness, is still more than modest:

  • Yi 4K Action Camera
  • USB cable
  • quick guides

As you can see, there is neither a power adapter, nor even a strap. Probably, the manufacturer believes that such little things will surely be found in any user. And in large numbers. Well, the developer is probably right somewhere.

A standard-looking “brick” differs from most standardized cameras of this design with slightly rounded sides and slightly larger dimensions, and only in width. Because of this, the camera does not fit into any of our waterproof boxes, which fit (as we naively believed) all the “bricks” on the market.

Discreet design, housing with a single control button, standard location of the USB port, poorly protected from moisture by a hinged flap. Well, what is so special about it, it would seem? And the special thing here is the display. Clearly “fresh” generation, high-resolution, touchscreen. over, its sensibility is not conditional, when, due to the microscopic size and poor-quality sensor of the first generations, every now and then you are mistaken by clicking in the wrong area. And “real”, as in good current smartphones. It is extremely difficult to make a mistake here, since the display diagonal is 2.19 inches. The rest of the display specs also inspire respect: 640 x 360 resolution for 331 ppi, manufactured by AUO, covered with Corning Gorilla glass, and 160-degree viewing angle.

READ  How to make an Action Camera from your phone

Thus, now we are watching. finally! the process of introducing quite new technologies into action cameras. Frankly, I got bored of contemplating old displays taken from dusty warehouses. But the display is not all innovation. The video processor used in this camera also belongs to the new generation: Ambarella A9SE75. And the CMOS sensor that receives the image is also not outdated. it is a 1 / 2.3-inch 12-megapixel Sony IMX377. Another full-size video camera will be jealous of such technical equipment.

over. The presence in the camera of a certain six-axis gyroscope is promised, which helps to eliminate the shaking that is familiar to absolutely all action cameras. It is a pity that we cannot disassemble the apparatus and examine this curiosity thoroughly under a microscope. Well, to check it in practice, we hope it will work out.

Another important design feature of the camera is the presence of a threaded standard hole for attaching to a tripod. Thus, there is no need for any branded. usually expensive. accessories. Since any tripod, bracket, or other attachment equipped with a standard 1/4 “thread will work to mount the camera.

The supplied battery with a high capacity of 1400 mAh allows continuous video recording for 110 minutes in the “senior” format 3840 × 2160 30p with Wi-Fi turned off.

During long-term recording, the temperature of some structural elements (for example, the area around the lens) reaches 56 ° C, but the camera does not react to this heat in any way, and continues to work properly. This makes me happy. Since almost every second modern gadget. especially a miniature one. suffers from such a drawback as overheating with a mandatory emergency shutdown for cooling. Our camera is devoid of this drawback, we note this most positive fact.

Yi 4K Action Camera with 4K Long-Term Recording, Touch Screen and Settings

Not so long ago, we studied the predecessor of the device under review and described it as a sleek camera with an underutilized potential. This disadvantage was the lack of high resolution that the camera could provide. I wonder how this is the case in the new model. After all, it is capable of recording video with a frame size of 4K, which in itself requires a very high resolution without artificial damage to it. Of course, it is curious to know other characteristics of the device included in the list of basic parameters.

  • Design, technical characteristics
  • Video / photography
  • Software
  • Comparative testing
  • findings

The mobile application that you can use to control the camera has a wide range of resolutions and frame rates with which you can shoot. Even too wide. It looks like this:

However, in the service menu of the camera itself, the list of all possible resolutions and frequencies is arranged somewhat differently, more logically: next to the choice of resolution there is an arrow leading to the choice of frequency. If there is no such icon, then there is no choice. Thus, if we arrange the list of formats available in the camera in a more orderly way, then it will actually consist of 17 formats and look like this:

Format Options
Name, permission Frequency Video codec Bitrate, Mbps
one 3840 × 2160 30p AVC H.264 Main@L5.1 60
2 3840 × 2160 Ultra 30p 60
3 2560 × 1920 30p 45
four 1920 × 1440 30p thirty
five 1920 × 1440 60p 45
6 1920 × 1080 30p thirty
7 1920 × 1080 60p 45
8 1920 × 1080 120p 60
9 1920 × 1080 Ultra 30p thirty
ten 1920 × 1080 Ultra 60p 45
eleven 1920 × 1080 Ultra 120p 60
12 1280 × 960 60p 45
thirteen 1280 × 960 120p 60
14 1280 × 720 240p 60
15 1280 × 720 Ultra 60p 45
16 1280 × 720 Ultra 120p 60
17 848 × 480 240p 60

As you can see, the word Ultra is present in the names of six lines. Given that all other parameters exactly copy the parameters of neighboring formats. What is the difference, how, for example, the 1920 × 1080 format differs from the 1920 × 1080 Ultra format? The frequencies are the same. And the resolution is an exact copy. Perhaps the answer lies in bitrate? No, and the bitrate is exactly the same in all the same formats, Ultra or not Ultra. Even the distribution of keyframes in streams is the same? except that the bitrate is spent on them a little more. So that is almost imperceptible. Maybe that’s the difference?

3840 × 2160 3840 × 2160 Ultra

Again, no. But everything turned out to be very simple. The camera angle is the secret. The word Ultra in the name of the mode means a slightly wider viewing angle than in the same mode, but without the word Ultra. However, the way in which this wide angle is preserved in the video seems rather odd. The developer decided that the wide angle is more important than the absence of geometric transformations. He simply took a wide shot and flattened it horizontally to fit the panorama to standard sizes. Like this:

It turns out that by choosing the Ultra mode, you will either have to get used to flattened faces, or stretch the video horizontally in width, while losing detail. But then why did we shoot at Ultra Wide Angle? Unclear. Well, okay, let’s leave these Ultra-labels to marketers who like to use bright words to describe the most banal ideas in order to present them to a potential buyer as manna from heaven. Let’s get down to business.

The following should be added. Each of the formats has three more levels of settings. Namely, the quality of the encoding. High, Normal and Low. We will definitely return to this question, having studied the difference in the quality of video recorded in different modes. But be warned: this article will only use the highest quality video captured in High mode.

By the way, this whole table of 17 items can. and should. be doubled, since the camera has the ability to switch TV systems from NTSC to our “native” PAL system. Accordingly, with such a switch, the frame rate will change in all formats without exception. For example, 4K will have 25 frames per second, and 848×480 at the original 240p will “lose” as much as 40 frames per second, becoming 200p.

At the first glance at these freeze frames, I immediately remembered the feature of the previous version of the Yi action camera, which we talked about in the introduction to this article. Namely. too strong artificial blurring of the picture. Apparently, the developers realized their mistake. And in the new version, the cameras took and. oversharp the picture! That is, they made it too harsh, unnatural. Typically, this sharpening is used to enhance the contrast of the edges of objects so that, for example, a security camera gives a more readable picture of a license plate. But after all, in most of the modes with which our camera shoots, skipping lines is clearly used when reading from the matrix. This omission always leads to the appearance of ladders, steps at the boundaries of contrasting objects. What if we sharpen up even more? That’s right, the ladders on the same wires will become even more noticeable. What, in fact, happened.

READ  How to enter the web interface of the IP camera

Some modes still work better, sharping with dirty splashes and ladders in them are not very striking. Such modes in our case are 2560 × 1920 30p and 1920 × 1080 60p. But the first of these modes has an aspect ratio of 4: 3, which is not very convenient if the Honor has the 16: 9 aspect that is common today. It turns out that the only option remains the only one, 1920 × 1080 60p? Perhaps yes. However, for this article, we will still be shooting in the very first mode, 3840×2160 30p. After all, the 4K standard (by the way, 4K letters can be seen even on the camera body).

The other modes not mentioned are not at all interesting for everyday shooting: high-frequency Full HD 1920 × 1080 120p and ultra-high frequency HD 1280 × 720 240p have all the signs of blurring and low resolution. Of course, you can use these modes as rare spectacular inserts with strong slowdown. over, in high-frequency modes, sound is recorded along with the video, which is very rare.

But the main modes for everyday shooting are still recommended to be 3840 × 2160 30p and 1920 × 1080 60p. Of course, none of the readers is obliged to agree with what has been said. after all, everyone has their own quality standards and even more so the size of the frame.

The next question will be resolution. Due to the strong geometric distortions that our wide-angle camera gives, it will be possible to visually measure it only with the help of a part of the test chart printed on a 1-meter sheet of paper. Filming taken from different distances is subsequently superimposed in a video editor on a full-size version of the whole table until the size of the key element matches, which is taken as an answer.

The result is very good! 1400 HD 4K TV lines. Of course, in Full HD mode, the resolution turns out to be significantly lower than in “just Full HD” cameras, reaching 800 TV lines.

Let’s touch on another shooting mode that affects the change in the angle of view: shooting with the stabilizer on. As it turns out, the camera uses an electronic stabilizer. Read. software. We’ll evaluate its effectiveness later, but now let’s take a look at how much this stabilizer cuts the edges of the frame. Indeed, for software stabilization to work, a lot of free space is required at the edges of the matrix, hence the well-known crop.

Yes, this is exactly the effect of the activated stabilizer. the frame is cropped evenly from all sides, while there are no geometric distortions, as in the Ultra shooting modes.

This is where it is proposed to complete the study of formats and a preliminary assessment of the quality of shooting. over, so far it was only about shooting mostly static. But the camera in question is intended for completely different filming, in which there is a lot of movement. And any movement, especially if the camera is fixed on something moving, is, first of all, a shaking video. Which, although sometimes impressive with a plot, is suitable for viewing only conditionally.

The stabilizer, which is available in any self-respecting “full-fledged” video camera, is called upon to correct the shaking. First of all, we now mean optical stabilizers, which are an extremely complex system that consists of optics floating in a magnetic field. The strength of which, in turn, changes according to the signals of the position sensors. Thus, the position of the lenses is corrected and, accordingly, the alignment and smoothening of the image entering the matrix occurs. It’s hard to believe that it is hard to build such a system into an action camera that has a miniature size and, moreover, is periodically subjected to accelerations or impacts. If the size of such systems is reduced to microscopic ones and they are built into the corresponding chambers, then the efficiency of such systems will sharply decrease according to their size. So far, the optical stabilizer has been implemented only in cameras with a so-called pistol grip, here is one of the successful examples.

In our case, electronic stabilization comes to the rescue, that is, software. Its operation requires a powerful processor and a sufficient free area of ​​the matrix, on which the corrected image will “float”. We just saw the result of how the camera’s field of view narrows when stabilization is turned on. From this, a logical conclusion comes from this: such stabilization cannot be carried out in all shooting modes. For example, in 4K, when there is no free matrix area or the processor is not able to process such an array of information on the fly. That’s right, in our camera the stabilizer will not always turn on, not in any shooting mode. Below is a table that clearly shows such a possibility, depending on the selected mode.

Format The ability to turn on the stabilizer
one 3840 × 2160 30p not
2 3840 × 2160 Ultra 30p not
3 2560 × 1920 30p Yes
four 1920 × 1440 30p Yes
five 1920 × 1440 60p Yes
6 1920 × 1080 30p Yes
7 1920 × 1080 60p Yes
8 1920 × 1080 120p not
9 1920 × 1080 Ultra 30p not
ten 1920 × 1080 Ultra 60p not
eleven 1920 × 1080 Ultra 120p not
12 1280 × 960 60p Yes
thirteen 1280 × 960 120p not
14 1280 × 720 240p not
15 1280 × 720 Ultra 60p not
16 1280 × 720 Ultra 120p not
17 848 × 480 240p not

Everything is as we said. Turning on the stabilizer becomes impossible in two cases: with a large frame size (the entire matrix is ​​read and there is no free area) and at a high frame rate (the processor will not be able to float 120 or 240 frames per second). But let’s finally evaluate the effectiveness of this kind of stabilization in the performance of our camera. The shooting was carried out in the mode with the maximum frame size at which the stabilizer can be turned on (2560 × 1920 30p). the third mode in the list.

Well, very good. Of course, it is best to melt the shaking image so far with the most complex optical stabilization systems operating on the gyroscope principle, which are an optoelectronic system (optics plus a matrix), which is suspended inside the camera body. But what we have is what we have. An electronic stabilizer built into an action camera is already a tremendous achievement, a progress in processor design.

Another issue is the rolling shutter (for more details, see the material Rolling shutter in video. a description of the defect, examples, explanations). It is much more difficult to overcome, since it is one of the features of the CMOS sensors used, where information is read line by line. The faster the reading goes, the lower the level of the rolling shutter. By using interlaced reading (address), you can achieve a reduction in the rolling shutter, but the image quality decreases.

Above, in the rollers with stabilizers, one could observe the very “jelly”, which is one of the manifestations of the rolling shutter. The jelly doesn’t seem too noticeable, even if not distracted by evaluating the stabilizer. The next shooting was carried out in the maximum mode for the camera 3840 × 2160 30p.

The original file is too large to be attached to the article, and it is unlikely that it will be useful to anyone. After all, it is clear from the presented video that the rolling shutter still makes itself felt, no matter how fast the new matrix is.
