How to sell cameras more comfortably?

It's your fault that you didn't get extra points after reading it ~ ~ ~ I think it's most important to understand the customer's psychology. Principle 1. The technologically advanced product to be promoted is a hard index digital camera, which is an electronic and optical component that integrates a camera and a video capture unit. At present, there are basically two kinds of cameras on the market: one is a digital camera connected to a computer, which can directly shoot images and then transmit them to the computer through a serial port, a parallel port or a USB interface. The other is analog camera, which should be used with video capture card; The analog video camera can convert the analog video signal generated by the video acquisition equipment into digital signals, and then store them in the computer. The video signal captured by analog camera must be converted into digital mode by special video acquisition card and compressed before it can be converted into computer. Because a digital camera can be directly connected to a computer, you'd better choose a plug-and-play camera from the convenience of connection. Of course, if you already have a video capture card, you can also consider choosing an analog camera. In order to facilitate the connection with the computer, there are connecting wires behind the digital cameras now. Through this cable, the digital camera can be connected to the computer through interface card, parallel port and USB port. If you add a set of software that can shoot images instantly, you can realize live webcasting. However, when you choose an interface mode, you don't just choose one. You must choose the camera according to the purpose of use. Usually, the camera with interface card is realized by the camera special card, and the manufacturer will optimize or increase the video capture function for the camera, which has great advantages in image quality and video stream capture. However, due to the different interface card designs of different manufacturers, the products are not universal and the price is not cheap, so this kind of products are worth using by users who need to pursue higher image quality. At present, most camera interfaces on the market use USB interface, because this interface product has always been accepted by everyone because of its plug-and-play and convenient use, and it can also save external power. However, the transmission speed of USB interface is still not high, so if you want to get higher quality images and faster transmission speed with the camera, you still need to make great efforts in technology to solve it. Another connection mode is parallel port mode. The biggest advantage of this connection method lies in its high versatility, because basically every computer has a parallel port, but the data transmission speed is slow and the practicality is greatly reduced, but it is still acceptable for ordinary users. If you want the camera to shoot high-quality and high-definition pictures, you should focus on checking the lens components of the camera when choosing a camera, because the quality of the lens is the key factor affecting the image quality. The general principle for us to buy lenses is that the more famous manufacturing companies produce the better lenses. In addition, because the imaging area of the camera is related to the area of CCD or CMOS element, the CCD or CMOS element area of different cameras is not equal, and the imaging area is also different. There are two kinds of CCD elements: area CCD and scanning linear CCD. The photosensitive area of CCD chip of area CCD camera is a rectangular array plane, and the usual aspect ratio is about 3: 2, which has the advantage of fast capture speed. There are no special requirements for shooting moving scenes with ordinary flashlights. Common sizes are 1/ inch, 1/4 inch, 1/3 inch, 1/2 inch and18.4x27.6mm, 6.4x20.5mm and 9.2x1. The CCD chip used in scanning linear CCD camera is long and narrow, that is, the photosensitive tiny units are evenly arranged in a row, instead of being evenly arranged in several columns to form a rectangular plane like an area CCD. The resolution of linear CCD camera is extremely high, but due to the scanning process, the higher the resolution, the longer the processing time is needed. Generally, the area CCD digital camera should be used when choosing, and the scanning linear CCD digital camera can only be used for still life shooting. Compared with CCD elements, CMOS elements are cheaper than CCD elements under the same pixel, but the image quality produced by CMOS photosensitive devices is lower, and such elements are usually used for analog cameras. Principle two. Powerful product features are the goal. A good digital camera must have excellent technical indicators, as well as powerful use functions and control and management functions. Usually there will be a high-resolution camera, which has a strong ability to analyze images, so whether the camera is strong or not will also be reflected in the resolution of the camera. Generally speaking, the resolution of a camera directly determines the size of a shot image that can be printed with high quality, or the size of a picture that can be displayed on a computer monitor. When purchasing a digital camera, the resolution is the primary problem to be considered after the hardware index of the digital camera is determined. The resolution of a digital camera depends on the number of pixels on the CCD or CMOS chip in the camera. The more pixels, the higher the resolution. As far as similar digital cameras are concerned, the higher the resolution, the higher the camera grade. However, the data files generated by high-resolution cameras are very large, which requires high computer speed, high memory and hard disk capacity and corresponding software. Obviously, the larger the size of the digital photo to be printed, the higher the pixel level of the digital camera is required. At present, the resolution of mainstream products is designed according to 300,000 pixels, which supports the maximum resolution of 640×480. At this resolution, the speed of 15 frames can be provided, and the picture is obviously paused and somewhat blurred. When the resolution is reduced to 352 x288(65438+ megapixels), the camera can usually provide 30 frames, so that you can see a very smooth picture. At this resolution, the picture becomes very clear. In addition to supporting the resolutions of 640×480 and 352x288, the camera can now support the still image capture capabilities of various resolutions such as 160× 120, 176× 144, 320×240 and 704×576. Perhaps the biggest factor affecting the image quality is the camera's video capture ability. At present, the maximum resolution of pictures taken by digital cameras is 704x576. So far, no digital camera can capture 30 frames per second at this resolution, so the picture will jump. Although many manufacturers boast that their cameras can capture 30 frames per second at the highest resolution when promoting their products; At this time, you should pay attention. You can't easily believe the cheating tricks of profiteers. What you can do is to compare which camera can capture the same resolution by combining hardware and software. Of course, we can't blindly pursue video capture ability, because the higher the video capture ability, the higher the requirements for computers. For example, the video capture capability of 30 frames per second requires that the processing power of CPU is fast enough, the memory capacity is large enough, and the installed operating system software is at least windows98；; If your computer doesn't meet the requirements, it won't help even if the video capture ability of the selected camera is high. The color of the camera and the ability to adjust the light source are also very important for the efficient work of the camera. Especially the functions of backlight compensation and white balance adjustment, because these functions are well controlled, the video picture can be played harmoniously and naturally. The function of white balance adjustment is similar to adding color temperature conversion filter in color photography. The purpose is to get accurate color reproduction, but white balance control does not need to add a color filter in front of the lens, and adopts circuit control mode, which is divided into automatic adjustment and manual adjustment. You can choose the appropriate control mode according to different use environments and requirements. In addition, the quality and function of bundled software are also important factors to consider when purchasing digital cameras. Because the realization of camera function can not be separated from the support of software, most cameras have special control programs to realize the most basic functions such as taking pictures, shooting, managing image files, setting, etc., thus serving as a tool for users to directly control and use cameras. Now most manufacturers' products will be equipped with video conferencing, video chat, video recording, photo editing, anti-theft detection and other software. Some of these softwares are often aimed at beginners. For example, photo editing software will have a large number of templates and creative tools, and even users who are new to graphic editing can use their imagination to post-process photos. Video communication software can guide users to carry out video mail, video phone and other applications; Through these bundled software, users can get more application schemes. Because the ease of use of the software directly determines the user's actual experience, everyone must check and compare the functions of their own software. Principle 3: Pay attention to brands and services. In addition to the camera technology and functions mentioned above, we should also pay attention to some external factors when purchasing, such as product design, cost performance, brand and after-sales service. In fact, because the technical content of making cameras is not high, it is difficult to distinguish cameras of various brands by comparing their internal performance. Therefore, these external factors mentioned above often become the main consideration when people buy. For example, the appearance of a product is an important factor that affects people's choice. As a new type of video equipment, the users of cameras are mainly computer upstarts who pursue fashion. Therefore, there is no reason not to choose a beautiful or fashionable camera when the performance is equivalent. In addition, the following factors should be considered: 1, the company image and reputation of the manufacturer. Mainly to make a more comprehensive understanding of manufacturers' advertisements, service commitments and word of mouth; 2. Whether the marketing service system of the manufacturer is perfect. Understand whether its sales and service distribution outlets are sound, and don't go to Shanghai to solve the problem of products in Chongqing. 3. Understand the situation of other products operated by the manufacturer. This will be a good reference for you to choose a digital camera. Principle 4. Sufficiency-oriented. The purpose of people's shopping mainly lies in application, and it is based on the principle of sufficiency. The same is true for choosing a digital camera. Each product has its own unique application field. Some merchants use the characteristics of their hardware equipment to add a lot of software with application value on the basis of shooting and capturing images, such as image mail software, audio-visual chat software, simple video editing software and so on. With the help of various softwares, you can use the email function when shooting scenes, edit the pictures simply, and have video chat and other functions. When choosing, you should be clear about the purpose of your purchase, guide consumption with application, and it is cheap and good, which can fully meet the demand. In addition, when buying a camera, we should first choose a brand according to the use requirements and whether the funds are sufficient, and then compare the prices under the same brand. High-priced performance may be better than low-priced performance. But the price brand is only a subjective feeling, and to really choose a good digital camera, we must carefully choose a good focal length combination. Finally, I want to remind you that the camera you choose must cooperate with your own computer system to form a complete shooting system. In the same system, the quality indicators of all kinds of equipment must be consistent with each other. If the equipment with inconsistent indexes is selected, the final result will only reach the lowest index, so the money spent on the equipment with high indexes will be wasted.
