Here are a few common questions about buying a camera:
1. Does the camera need to be driven?
All the cameras in this shop do not need to be driven under XP2 or above/VISTA/WIN7 system, and can be used directly by connecting to the USB interface of the computer.
2. The camera has several million pixels. How much is 8 million? How much is 10 million?
This is the most common question asked by customers who buy cameras. I usually connect the camera to let customers see the effect of the video. The effect I see is the most real, because I said it is 1 million, and the customer may leave immediately. Yes, because he heard more than a few million. I said it was 12 million and 15 million, but I felt it was against my intentions. At present, the highest hardware pixel of a PC camera is only 1.3 million. The common ones on the market are generally 300,000 and 48. Million, the so-called 12 million and 15 million refer to software interpolation. Software interpolation means that you can take pictures with the size of 12 million and 15 million pixels in the software. Simply put, it is to enlarge the picture of 640X480 to 1024X768 or larger. Some, and then use the software to calculate the color difference between the resolution points of the picture, and fill the enlarged part in the middle with the color calculated by the software. Although the output image is larger, the quality of the image is not improved, but is seriously distorted. In fact, it is impossible for a camera to reach several million. Think about how a few tens of dollars can have an effect of several million. In short, you must see is believing when you buy a camera.
3. Why is someone else''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s exactly the same as yours, only XX yuan for 12 million and 15 million, while yours is more expensive?
When buying a camera, don’t listen to others saying that it’s millions of pixels. It’s explained above. It’s software interpolation. You have to see the effect with your own eyes. Don’t compare the price by looking at the appearance. Now the cameras on the market have the same shape and the price is from Ten yuan to tens of yuan, there will be N kinds of prices, why? The video effect of a camera is determined by its three major parts: main control chip + photosensitive chip + lens, each type of chip and lens is expensive and cheap Yes, the products prepared in this way will have many effects and different prices. It is definitely one point for one price.
4. Are there special effects? Can I make a video?
All cameras can achieve special effects and video recording functions. It is only necessary to install the corresponding software. Although it is only a small amount of money to burn software discs, I think there is no need to burn. Now it is the era of the Internet. Utilizing network resources is not as good as price concessions, which really allows buyers to get real benefits. There are many such small software on the Internet, and I can provide website downloads.
5. How to choose a good camera?
The quality of a camera is determined by its three major components: the main control chip, the photosensitive chip and the lens. For professionals, one can know the effect by looking at the model of each part. For most friends who are not familiar with the camera industry, tell An easy way for you to choose a camera: 1. Look at the static definition, connect directly to the computer, and see the effect with your own eyes(Don’t ask if it’s millions. The mainstream camera hardware now has 300,000. Millions and tens of millions refer to software interpolation. The pixel size of software interpolation is not directly related to the video effect.)2. Look at the dynamic speed, wave your hand in front of the display screen to see if there is smear. A good camera basically has no smear. Such a camera has clear and smooth images during video.
The higher the pixel, the better the effect. At the same time, ensure that the network is good, because the higher the pixel, the larger the transmission data of the network video, so keep the network unblocked, so that the other party sees a smooth picture.
Please note: The lens ring can be rotated to adjust the focus. Some buyers reported that this camera is not clear, the root cause is that the image is not in focus because the focus is not adjusted, and the imaging mode
