Xianyu "picked up the missing Mi Camera 2 AI enhanced version" for 120 yuan, and went to the after-sales service to fix it for free.

I am a heavy user of Xiaomi cameras. I have used them since the first generation of 720P, and later changed to 1080P, 2K, and 2.5K. Until recently, I saw the AI ​​enhanced version of Xiaomi Camera 2 (referred to as Xiaomi Camera 2A) and got an idea. Get a replacement for your home. My requirements for the camera are very simple, that is, clear pictures and clear calls, which requires the external speakers to be powerful enough. The Xiaomi cameras I have used before have improved the image quality with every upgrade, but the external playback always felt unsatisfactory.

According to the introduction on the Xiaomi Camera 2A promotional page, its external speaker is currently the strongest in the Xiaomi series, because it uses a large-diameter PU PEI diaphragm speaker with independent sound intensity, harmonic distortion as low as 3%, and a cavity It has a body sound conductor design, and a wrapping cloth design is used on the outside. Just when I was about to buy it, Xiaomi Mi Camera 3 suddenly came on the market quietly, which made me unable to make a decision for a while. Due to my demand for image quality, the pixels of Xiaomi Mi Camera 3 were increased from 4 million to 5 million, so I chose to buy it first.

As for why I bought 2A again later? Because only children make choices, and adults want them all? Don't talk nonsense, it's purely because of the success of picking up the leak.

While casually browsing on Xiaohuangyu, I found a Xiaomi Camera 2A priced at 146 yuan with free shipping. Its fault was that "the picture was stuck". My idea at that time was to carry out after-sales maintenance after purchase, because the 2A mobile phone was launched in October last year, less than a year ago, and Xiaomi’s warranty service does not require an invoice. But the seller told me that it cannot be repaired for free because the SN code has lost the warranty. I decided to take a chance and if it didn't work I would pay to fix it myself. In the end, I spent 120 yuan to complete the transaction with free shipping.

I made an appointment with the local Xiaomi after-sales service on the day I got it, and took a video of the screen failure in advance. I went there at noon the next day when there were fewer people. As a result, the after-sales service department accepted the product without saying a word, and did not ask for an invoice during the entire process, nor did they mention the issue of the SN code being invalid after-sales service. However, due to the lack of spare parts, the after-sales staff asked me to wait for about 3 days, and they would notify me to pick them up after repairs were completed.

I was notified to pick it up three days later. As can be seen from the maintenance record, the motherboard was replaced directly after the sale. Then the warranty period starts from April 15th and can be renewed until April 15th next year. At this point, picking up the leaks is considered a success. This reminds me of a colleague who sold me an iPad with a black screen for 1,000 yuan ten years ago. I also went to Apple after-sales service with the attitude of giving it a try. The first time was at Apple after-sales service in Sanlitun, Beijing, and they refused to guarantee it. The second time I switched to Xidan Joy City Apple After-sales Service, they replaced me with a new one without saying a word, which made me earn two to three thousand for no reason, which was almost half a month's salary. Therefore, after-sales warranty is sometimes very mysterious.

Next, let’s talk about the differences between Xiaomi Camera 2A and Mi Camera 3. This is a simple review.

I mainly use Xiaomi Mi Camera 3, which has been placed on top of the upright air conditioner in the living room for the past few years. There is no need to hang it on the wall. This position can capture the entire living room. In order to test the difference in images, I also temporarily placed 2A in the same position to take screenshots. Let’s take a look at the comparison sample below:

In terms of resolution, 2A is 4 million pixels and 3 is 5 million pixels. If you don’t zoom in, the image quality and fineness are almost the same, but 2A has warmer tones and 3 has cooler tones.

After enlarging the picture, it looks similar to the naked eye, but 3 is indeed slightly clearer, and the picture exposure control is better, and it will not be overexposed like 2A.

The effect at night is very different. 2A is brighter, but the color is distorted and the picture is yellowish, while 3A is obviously much darker, but the picture is closer to reality. It is impossible to say who is better and who is worse. My wife thinks 3A is better. While the 3 has 1 million more resolutions than the 2A, the gap between them isn't that huge. Unless your home previously had a 720P, 1080P or 2K camera, suddenly switching to the third generation 5 million pixel camera will feel like a big improvement.

Next, let’s talk about the call quality. I tested it several times and found that the external amplifier of 2A is indeed much better. The volume is louder and richer, and the sound quality is obviously much better, not sharp, and there is no noise. For this upgrade, I plan to send 2A to my grandpa’s house for use. He is currently using the old 2K version, and every call will be drowned out by the TV sound. It will definitely be better to switch to 2A this time, and there will be one more call. Buttons can also be used for emergency purposes.

Although the external amplifier power of Xiaomi Camera 3 is not as good as 2A, its microphone has stronger sound pickup ability, so the monitoring sound can be heard farther and clearer from the mobile phone. According to official information, the pickup distance of the Type 3 camera is 8 meters, while the pickup distance of all other cameras on sale (including Type 2A) is 5 meters. Therefore, except that the external playback of 3 is not as good as 2A, everything else is worse than 2A, especially the price of more than 200 yuan, which is more than 100 yuan cheaper than 2A. As for the extra local AI face recognition, local AI pet recognition, regional care and 360° panoramic cruise/scheduled and fixed-point cruise functions added to the 2A, I won’t go into details since I can’t use them at home.

How to choose? If you mainly use the camera to talk, then 2A will be better. If you mainly watch the surveillance screen, then 3 will be better. If you have any unresolved questions, please ask in the comment area and I will reply one by one.
