Which camera is better for live broadcast? Please recommend a brand

Live broadcast camera is still very important. If it is only used for entertainment, it will not be used to carry goods during live broadcast or become a professional live broadcast. People, then a mobile phone is enough. There is no camera without a camera. As long as the picture and video are normal, it is OK. If you want to go further on this road, a good camera is essential. , only good pictures and high-definition experience can leave a deeper impression on people, and others will insist on coming to your live broadcast room.

Mairbox live broadcast equipment manufacturer comprehensive suggestions: three major parts of live broadcast equipment - camera, condenser microphone, Independent sound cards and cameras are the most important, so don’t be too frugal in investment. If your pocket is tight, you can buy a set of condenser microphone and independent sound card, which only costs four to five hundred yuan. In this way, the investment in live broadcast equipment can be controlled. Within a reasonable range;

Mairbox HD live broadcast equipment M2 HD camera: Most jewelry and clothing live broadcasts will use cameras with pan-tilts and optical zooms, and the focus of the shooting can be controlled through the remote control and angle. In most cases, the anchor will set the focus and angle in advance and will not change these two parameters at will during the live broadcast. Because temporary adjustments during live broadcast will affect the screen layout and focusing speed, giving customers a poor experience. In order to solve this problem, this type of live broadcast camera will provide a camera position preset function.

Selection of live broadcast microphones: Common microphones are divided into two major categories: condenser microphones and dynamic microphones, as well as vacuum tube microphones, aluminum ribbon microphones, electret microphones, etc. that are not common today. Because of the current live broadcast Condenser or dynamic microphones are used for recording. Mairbox, a live broadcast equipment manufacturer, also mainly uses related microphones for live broadcasts, so it develops its own condenser and dynamic microphones that are more suitable for live broadcasts. Of course, there are also There are some smaller bees that are portable and can also be used.

1. High-definition camera, as the source of high-definition video. When choosing a camera, you need to pay attention to whether the output port is HDMI or SDI, and it matches the cable interface. (We take HDMI high-definition transmission as an example below). The pixels captured are generally 1920*1080P (ultra high definition). I recommend several camera models at random, generally Sony MC2500 (market price starts at 6,500), commonly used ones are Sony 2800, Sony nx100, Sony nx3, etc. (market price is between 8,000-20,000). Naturally, the more expensive the cameras used for large-scale conferences, the better the video quality. However, the ViviStar live broadcast team believes that we cannot blindly pursue good cameras. Good cameras must be deployed by professionals, otherwise it will be useless.

2. Video capture card, which captures high-definition video and outputs it to the computer through the USB interface. First, make sure the interface is an HDMI interface (the same as the camera and cable), and then the capture resolution is generally divided into 60 frames and 30 frames. Generally, 60 frames corresponds to 1080P, and 30 frames corresponds to 720P. The price starts at more than 300, and 60-frame video is much more expensive. If the budget is OK, 60-frame video is generally recommended. After all, we want to do as high-definition live broadcast as possible. If the frame number is too low, no matter how good the video source is, it cannot be captured.

3. A high-definition video transmission line, consistent with the camera interface, HDMI interface, 15 meters, about 200 yuan. Just search directly on Taobao and Tmall.

What camera is better for live fishing?

Hello, as an amateur fishing enthusiast, I am happy to answer your question. I use a Sony FDR-AX700 camera. The main reason is that the human eye has a very wide recognition range. When the shooting environment is bright and dark, it is difficult for imaging equipment to record images as detailed as what can be seen with the naked eye. However, the Sony FDR-AX700 camera with HDR function can provide a wider color gamut and gray scale range when shooting, bringing images closer to reality.

As for the stand, I use the VCT-668RM, which is light and compact and easy to travel. The most important thing is that it can also rotate 360 ??degrees horizontally. The height of 148cm can meet the needs of normal photography. It has adaptive rotatable feet and can easily adjust the angle. It is suitable for many It has anti-skid and wear-resistant effects; it adopts plate-buckle fixation, which is more stable. After opening the tripod trigger, you can stretch and reduce the leg tube to facilitate adjusting the height of the tripod.

Question 2: What kind of camera is best for the anchor? Please recommend. Nowadays, many anchors want to buy a camera before starting a live broadcast. However, after searching on Taobao, there are so many types, including cheap and expensive ones. Which one is better? As the saying goes, if you want to do your job well, you must first benefit it. It is also very important to buy a host camera. Why? It is very simple. The effect of a good camera in the live broadcast room is of great help to your popularity. Generally speaking, we will recommend that anchors buy a high-definition camera. For cameras, do not use infrared. Recommended brands include Logitech C920 or AFV C920. Of course, AFV also has the AFV 6

Plus, but the prices of these brands are slightly higher. But if you find a good platform, the money invested in these equipment can be earned back quickly.

The cameras of the anchors determine the popularity of the anchors to a large extent. For a girl who looks like a flower in real life, the camera is really ordinary, and the live broadcast effect may be greatly reduced. , it is said that if you want to do your job well, you must first sharpen your tools. How to adjust the anchor's live broadcast camera to get the best effect? ??In a few days, we will take a look at how to adjust the anchor's camera to be better and highlight the anchor's elegance. .

Selection of camera brands

Generally speaking, there are two options, infrared and high-definition cameras. Let’s take a look at those anchors with good video effects, whether they use infrared cameras. I still use a high-definition camera, and the effect is very good. It is recommended to use the two brands of Love C920 and Logitech C920. YY Korean BJ anchor Park Jialin uses Logitech’s high-definition camera for live broadcast. Most anchors on domestic platforms use infrared cameras. More often than not, now, basically all live video studios with a slightly higher quality use high-definition cameras.

Adjustment of lighting effects

After selecting the camera, the next step is to adjust the lighting effects of the live broadcast environment. It is recommended to use a desk lamp. When broadcasting at night, turn on the ceiling light in the room. The light must be bright. The function of the table lamp is to provide supplementary light. One should be placed on the left and right sides. It is recommended that the light can cover the whole body.

Camera placement angle

Generally speaking, the camera placement angle is placed directly above the live broadcast position, with a slight downward angle, as shown in the picture below.

The anchor's camera in the picture above is placed slightly downward, so that the anchor's image is more three-dimensional, and the impression given to the tourists below is also that wow, the figure is the visual sense. Debugging the anchor's camera is an important link. Because it directly affects your appearance.

Question 3: What kind of camera is good! ? Get rid of purchasing misunderstandings: When buying a camera, look for the correct lens. If the lens is not good, no matter how beautiful your face is, it will not show up. Some people compare the lens to the soul of the camera. Although this metaphor is a bit exaggerated, the importance of the lens to the camera is indeed an indisputable fact. On the surface, the camera's CCD or CMOS sensor element has limited resolution, and the optical resolution requirements for the lens are not too high. However, the photosensitive area of ??CCD or CMOS photosensitive elements is very small, which places higher requirements on the resolution of the lens. If the resolution of the lens is poor, even if the camera can achieve millions of pixel values ??in hardware, its image quality is likely to be only at the level of a 300,000-pixel camera. Correspondingly, for two cameras that use the same type of photosensitive element and DSP chip, whoever uses a better lens will have better image quality. Currently, most mainstream camera lenses on the market are composed of multiple lenses. There are three main types according to materials: 1. All-glass lenses composed entirely of glass lenses, mostly with four-layer (4G) or five-layer (5G) structures; 2. .All-plastic lenses composed entirely of plastic lenses are generally two-layer (2P) structures; 3. Glass-plastic hybrid lenses that match glass lenses with plastic lenses are mostly two-layer glass lenses plus two layers of plastic lenses (2P2G) combination. In theory, all-glass lenses can produce clearer images than all-plastic lenses. This is because the light loss of light passing through ordinary glass lenses is usually only 5 to 9, while the light loss of plastic lenses is as high as 11 to 20, resulting in a darker picture and increased noise. Some lenses also use multi-layer optical coating technology, which effectively reduces the refraction of light and filters out clutter, improving the light transmittance and obtaining clearer images. From the current point of view, although all-glass lenses have better optical performance, they are more expensive. Therefore, they are often used in some high-end cameras, but are rarely used in low-end cameras. The biggest advantage of all-plastic lenses is that they are cheap and are often regarded as low-priced. Low-end cameras with the main appeal are widely used. The performance and cost of glass-plastic hybrid lenses are between all-glass lenses and all-plastic lenses, and they are cost-effective, so they are widely used in mid-range and high-end cameras. Experts teach you how to choose a lens. When purchasing a camera, although it is difficult for us to identify the number of layers of lenses and the material of the lens by naked eye observation or disassembly, we can use the material of the lens housing to help identify it. Usually, the casings of five-layer all-glass lenses are mostly made of metal, while the casings of two-layer all-glass lenses and four-layer glass-plastic hybrid lenses are mostly made of plastic. The identification method of a fully plastic lens is also very simple. Tap the lens lightly with your fingers. If it makes a dull "bang bang" sound, it is probably a fully plastic lens (the surface layer of a glass-plastic hybrid lens is generally a glass lens); If it is a glass lens, it will make a crisp "ding" sound. At the same time, you can use the camera with a known all-glass lens and the camera you want to buy at the same time in a dark environment. If the image quality of the latter is much worse than the former, with obvious characteristics such as uneven light sensitivity and high noise, It is likely to use a fully plastic lens. You can even scratch the surface of the lens with your fingernails. Plastic lenses are easy to leave scratches. Most glass lenses are intact. However, you need to think carefully before doing it. It is very likely that the lens will be seriously damaged. Sometimes, merchants will tell you that the lens uses coating technology, which is easy to tell. We can observe from the side of the lens. If coating technology is really used, the surface will mostly appear blue-violet, blue-green or red. Some people think that coated lenses must be all-glass lenses, but this is not necessarily the case. In fact, the surface of plastic lenses can also be coated. However, coating has higher process requirements and is more expensive. All-plastic lenses whose main goal is low price rarely use this technology. Therefore, when purchasing, you can also identify fully plastic lenses based on whether the lens surface is coated.

Question 4: Which surveillance camera is better? There are currently 4 types of cameras: analog, parallel digital, FireWire camera, CameraLink high-speed camera; image capture cards also correspond to them, and better ones such as National Instruments ( NI) image capture cards are used in more important occasions (such as treasury), and the quality is very good; high-speed disk transfer solves the problem of storing high-quality images (currently the best domestic high-speed disk transfer can reach 100M/s (Actual speed) Cameras I have used are better from abroad. Domestic cameras have more problems. The simulated parameters are resolution. Digital cameras do not have such a parameter as resolution and only have capture bandwidth limitations. A set of ordinary hardware systems (high-speed streaming is temporarily replaced by SATA hard drives) is generally less than 10,000, and if the software is added, it will be 30,000. The price of a good system can exceed 1 million US dollars. The so-called imaging quality and clarity of monitors and camera lenses are different. In addition to the maximum number of lines (i.e. resolution), the imaging quality of the monitor is also related to the maximum apparent contrast. It is recommended that you go to the "Shenzhen Security Network" (cedm) to have a look, where you can get more satisfactory answers to most of your questions. . An article is reposted as follows: -－－－－－－－－－－－－－－－－－－－－－－－－－－－ Camera Lens Selection Guide In the TV surveillance system, how to adjust the scene to be monitored according to the environment? The correct selection of camera lens is very important, because it directly affects whether the effect of the monitored image seen on the end monitor of the system can meet the design requirements of the system (in terms of screen range or image details) after the system is formed. , so the correct selection of camera lenses can optimize the system design and obtain good monitoring effects. In terms of aperture, camera lenses can be divided into two types: manual aperture lenses and automatic aperture lenses. In terms of focal length, they can be divided into two types: fixed focus lenses and zoom lenses. Let’s talk about how to correctly select camera lenses based on different usage environments. 1. The selection of manual and automatic aperture lenses. The selection of manual and automatic aperture lenses depends on whether the illumination of the use environment is constant. For situations where the ambient illumination is constant, such as in an elevator car, a closed corridor, or a room without direct sunlight, a manual aperture lens can be used, so that it can be adjusted at one time according to the actual illumination of the environment during the initial installation and debugging of the system. Just adjust the lens aperture to obtain a satisfactory brightness picture. For situations where the ambient illumination changes frequently, such as in foyers, windows and lobbies where the illumination changes greatly with sunshine time, an automatic iris lens must be used (must be equipped with a camera with an automatic iris lens socket), so that Realize automatic adjustment of picture brightness and obtain a good monitoring picture with constant brightness. The control signals for automatic aperture lenses can be divided into two types: DC and VIDEO control, namely DC voltage control and video signal control. This depends on the selection of the type of automatic iris lens, the connection method of the camera's automatic iris lens socket, and the selection of the driving mode switch of the automatic iris lens. Just pay attention to the coordination of the three. 2. Selection of fixed-focus and zoom lenses. The selection of fixed-focus and zoom lenses depends on the size of the scene being monitored and the required clarity of the scene being monitored. When the lens specifications (lens specifications are generally divided into 1/3″, 1/2″ and 2/3″, etc.) are certain, the relationship between the lens focal length and the lens field of view is: the longer the lens focal length, the greater the lens’ field of view. The smaller the field angle (see Figure 1); when the focal length of the lens is constant, the relationship between the lens specification and the lens field of view is: the larger the lens specification, the larger the field of view of the lens. Therefore, it can be seen from the above relationship: when the object distance of the lens is constant, as the focal length of the lens becomes larger, the picture range of the monitored scene seen on the end monitor of the system becomes smaller, but the picture details become clearer and clearer. ; As the lens specifications increase, the picture range of the monitored scene seen on the end monitor of the system increases, but the picture details become increasingly blurred. Under the premise of certain lens specifications and lens focal length, the field of view angle of CS-mount lens will be larger than that of C-mount lens.

The field of view of the lens can be divided into the horizontal field of view of the image...

Question 5: What brand of camera is the best? Which camera is the best? I think 1) S real pixels of 640 Planting, bragging. A 3-megapixel digital camera that takes pictures can easily destroy a 10-megapixel camera. 2) A. The lens is large, that is, the aperture is large, and the shooting effect can be achieved by lighting a candle, but it will turn white when the light is strong. It is vast; it is difficult to make a high-quality lens with a large lens, and the price-performance ratio is poor B. The lens is relatively small, which is better in bright environments but not in dark light (Logitech is like this). Because the lens is relatively small, it is easy to make a high-quality lens with good cost-effectiveness C . Lens coating (if it looks purple, etc.), enhances the light passing through the lens and reduces the impact of refraction. D. Driver-free 3) Take pictures to see the effect of bright and dark environments (clear, no color cast, no smear). It’s very important. Today’s camera chips are mostly homogeneous. Lenses and appearances are different. Everyone likes the appearance. The key to choosing is the lens head, whether it looks good or not. Sometimes copycats also have good products at low prices.

Question 6: What brand of camera is the best? There are only two types of cameras, one with 100,000 pixels and the other with 300,000 pixels. In other words, the maximum is 300,000. Why aren't there higher pixels? Because if a camera wants to increase pixels, it usually increases the resolution through digital interpolation. This is tantamount to fraud without any improvement in clarity and image quality, which is the so-called interpolated pixels. On the other hand, if you want to improve image quality, increase the resolution. , the amount of data will inevitably increase geometrically. Not only the data transmission speed of the USB protocol cannot keep up, but the transmission of network data cannot keep up. The current conditions cannot meet such a huge data transmission speed, and online video chat will become very intermittent, unable to express continuous actions, and there will be no practical significance. If you don’t believe me, if you use a digital camera instead of a camera to watch the video, the effect will definitely be terrible, so a camera with 300,000 pixels is enough.

Some consumers will say, aren’t there many 350,000, 480,000, 680,000, 800,000, and 1.3 million pixel cameras on the market? We are going to tell you that this is the lie of the century about China’s camera pixels.

Image resolution/resolution (Resolution):

●SXGA (1280x1024) also known as 1.3 million pixels

●XGA (1024x768) also known as 800,000 pixels Pixels

●SVGA (800x600) is also called 500,000 pixels

●VGA (640x480) is also called 300,000 pixels (350,000 refers to 648X488)

● CIF is also called 100,000 pixels

Now everyone understands, why is it not capable of producing a 1.3 million pixel camera? I think any camera manufacturer in China, including us, has the ability to produce 1.3 million cameras. This is the reason mentioned in the first paragraph.

Misunderstandings between CMOS and CCD

There are two main types of camera photosensitive elements: CCD and CMOS. CCD has high imaging pixels, high definition, and high color reproduction coefficient, but the price is more than half that of S. CMOS has low price, low power consumption, and fast response speed, but in fact the difference between the two is very small. When using CMOS as the photosensitive Among the component products, by adopting advanced image control technologies such as image light source automatic gain enhancement technology, automatic brightness and white balance control technology, color saturation, contrast, edge enhancement and gamma correction, it can completely achieve the same level as CCD cameras. Comparable effects. In addition, the pixels of the camera itself are relatively low, so when it comes to the imaging effect of the camera, the difference between CCD and CMOS is almost non-existent and is affected by other factors of the camera.

About the camera solution

There is not much to say about the 100,000-pixel solution. Generally, it is the Sungyang 561. Now we will mainly talk about the 300,000-pixel camera solution.

The 300,000-pixel camera solution consists of a main chip and a photosensitive chip. Among them, the main chip of China Vistar Microelectronics is 301L (a substitute for 301P, now 301P has been discontinued). Other main chips include Songhan 102 and so on.

The photosensitive chips that 301L can match include Hyundai 7131E, Hyundai 7131R, and Micron 360. Among them, 7131E has been discontinued for a long time and has disappeared from the market. If anyone dares to say that they are using 7131E, there must be something wrong. The only two better solutions left now are:

301L Micron 360: This solution is the best solution on the market. However, because domestic Micron 360 chips are flooded with B-level products in the market, you can’t see the camera. The price reduction storms in the market come one after another. The culprit is that a large number of merchants use cheap B-grade Micron 360 chips to impact the market. In fact, the price of Micron's 360A-class chips has remained relatively stable. Our company has always insisted on transferring original A-grade Micron 360 chips from Hong Kong to ensure the interests of consumers. It is precisely because of this that some well-known camera brands at home and abroad have placed their production in our company. For example, the well-known camera brand "SUNTEC", whose camera sales in the New York area are second only to Logitech, made various choices and finally decided that our company would produce all series of cameras on its behalf.

301L Modern 7131R: Modern 7131R is a replacement for modern 7131E, but the effect is much worse than 7131E, and it also falls behind Micron 360. It turned out that its price was much cheaper than Micron 360 and there were more users. Later, Micron 360B chips flooded the market, and the price advantage of 7131R was lost. Now fewer people adopt this solution.

To sum up, most of the 301L models on the market now are...

Question 7: What brand of computer cameras is good? There are many good brands of computer cameras at present. Yes, when purchasing, it is best to choose those well-known brands, such as ANC Aoni, Blue Enchantress, Logitech, Extreme Speed, Liangtian, etc., which are among the top ten camera brands on the brand online shopping website. OK, you can compare before buying.

Question 8: What kind of surveillance camera is better to install at home? If you have important items at home, it’s best to install a camera. We use the Huanyufeiyang camera at home. It’s okay and we can see clearly.

Question 9: What brand is good for taking pictures with a camera? I bought a Logitech one before. The camera is very useful and has 5 million pixels. Unfortunately, I don’t know who borrowed it. Gone now!

During this period, I was comparing the ranking of the top ten camera brands on china-10, the top ten famous brand website, and felt that the above-mentioned ones, ANC, Aoni, Logitech, Blue Demon Queen, Taipower TECLAST, are well-known. The brands of cameras are all very good. I plan to buy another one. Let’s choose one from these brands! Once you see the specific model, you will know which one is better!

Question 10: Which brand of high-definition surveillance cameras is good? Hikvision, Dahua, Sony, Samsung, Honeywell, Panasonic, Philips are all fine!

What SLR camera is best for live streaming?

When choosing a SLR camera suitable for live broadcast, you need to consider many factors, such as image quality, autofocus, continuous shooting speed, portability, etc. The following are some recommended SLR cameras:

Canon EOSM6MarkII

This is a lightweight APS-C size mirrorless camera suitable for carrying out live broadcasts. It is equipped with a 325,000-pixel CMOS sensor and a dual-core DIGIC8 processor, capable of taking high-quality pictures and videos. At the same time, its fast autofocus and continuous shooting speed also ensure smooth live broadcast.

Sony A6400

This APS-C size mirrorless camera has up to 425 focus points and a continuous shooting speed of 11 frames/second, which can capture fast-moving situations. to a clear picture. It also comes with a height-adjustable screen, allowing you to easily take selfies or adjust the angle.

Canon EOSR

This is a full-frame mirrorless camera with a 303,000-pixel CMOS sensor and a fast autofocus system. It is also equipped with a high-definition OLED deformable screen and an optional electronic viewfinder, making it easy to view live broadcasts. In addition, it also supports functions such as wireless transmission and touch shooting.

Please note that the camera is only one part of the live broadcast. You also need to consider purchasing the appropriate lenses, microphones, lighting and other accessories to ensure that your live broadcast is the best it can be.
