Today's cars are equipped with many high-tech devices, such as anti-collision early warning, lane departure early warning, ACC adaptive cruise, etc. These devices can bring users a lot of convenience, ease of mind and ease of use.
However, the above mentioned configurations will only appear in the medium and high configurations of medium-sized cars. For ordinary families, they usually do not buy high configuration models, but choose more affordable cars. As a result, these high-tech configurations do not exist. This is the way most people will choose to make up for it in other ways. Can the "70 mile smart rear-view mirror M1" in my hand serve as a qualified substitute?
appearance
I usually have a rather antipathetic attitude towards this kind of intelligent rear-view mirror. Appearance is a key point, because they are a bit ugly, while the 70 mile M1 rear-view mirror（ Hereinafter referred to as M1 ）Good performance in appearance design, at least this time there is no resistance.
The almost frameless and square shape gives it a lot of points. What the author likes most is that the M1 is in the form of a buckle, which is directly fastened to the original rear-view mirror of the car. Therefore, users do not need to go to the garage to remove the original rear-view mirror, which is much more convenient than the so-called "smart rear-view mirror".

use
The installation process can't be simpler. You can directly buckle M1 onto the original rear-view mirror in the car, and then use the fixing clips in the accessories to fix it. If you have strong hands-on ability, you can also wire it yourself.

This M1 comes with a 4G SIM card and SD card, which are installed in it. After the power is connected, it can be used perfectly, which is very convenient. M1 smart rear-view mirror is equipped with an 8.88 inch display screen with a resolution of 1920 x 480. To be honest, the ppi is not high, but it cannot be measured by the standard of mobile phones. After all, the resolution is not important in actual use.
When the screen is closed, the display screen and the glass are almost integrated, which is no different from the ordinary rear-view mirror. When acting as a "rear-view mirror", it is fully competent. Even when facing the high beam dog at night, it is not very dazzling, which is better than the ordinary rear-view mirror.
Mobile&App and usage
When using the App for the first time, you need to log in and scan the QR code of the M1 rear-view mirror back shell for machine binding. There are not many functions in the App, and most of them can be realized in the rearview mirror.
However, there is a very interesting function called "WeChat Picking up". After clicking it, a link will be generated and sent to a friend. When a friend enters the link, his/her location will be sent to the M1 rearview mirror. At this time, you can pick up a person according to the navigation. However, its practicality is not very high. It is not as convenient as giving an address directly, but it is very interesting.

M1 rear-view mirror has its own speaker, which is quite loud. After the phone is connected to Bluetooth, the audio can be synchronized to M1. If the audio quality is good, don't ask too much, so this is why it can transmit through FM（ A Xiaomi product is also equipped with this function ）, output the audio to the car audio, so you can enjoy the car audio, NICE!
Some cars don't have Bluetooth function（ For example, author T-T ）, then a M1 rearview mirror can be used as a supplement. The mobile phone no longer needs to connect the cable to synchronize music. What's more, it can also make Bluetooth calls（ Although most cars today have this function ）。

In the whole use experience, voice control is one of the most practical functions that I personally think, because it is very handy. The way to wake up the rearview mirror is very simple. "Hello, Xiaomai", M1 will start to receive the command, "Navigate to Love to play computer games Headquarters "" called Cui Ye "" played the next "" captured video "and so on. The M1 smart rear-view mirror is equipped with the Gaud map, which has a very high accuracy. The route arrows can be displayed on the screen, perfectly replacing the mobile map app.
The recognition rate is the biggest highlight of voice commands. In 92% - 96% of the cases measured, the command can be correctly identified and corresponding feedback can be made. In many cases, it can even make Siri ashamed（ Although the functions are not enough, Siri has many ）, which frees hands, reduces the low head rate, and improves the overall driving safety from the side.
However, it is strange that when the mobile phone is connected to the rearview mirror to view the captured video, there is no option to download and save it to the mobile phone. If you want to export, you have to take out the SD card in M1 and use the computer to export the video. This is slightly worse than other similar products, perhaps because the shooting format is TS.

As an intelligent rear-view mirror, the function of the DASH CAM cannot be missed. In addition, M1 also supports the ADAS early warning function. The 1/2.9 inch OV2718 sensor it is equipped with is the basis for realizing this function. The f/1.8 aperture, 2.8 μ m unit pixel area, 160 ° wide-angle lens can record up to 1080p/30fps of video.
The most important thing of the DASH CAM is to be able to record the accident process and shoot the license plate number of other vehicles clearly, especially in the case of insufficient light at night, then let's look at a group of video samples and pictures:

The author has also made good use of the ADAS early warning function, which can realize collision warning, road deviation warning and front car start warning. In actual road conditions, the most feared thing is collision with the front car, so the practicability of collision warning is the highest.
In the setting of M1 rear-view mirror, the sensitivity of anti-collision warning can be adjusted. There are three gears: high, medium and low. I chose the middle gear to test. Before using this function, ADAS calibration is required, and monitoring can be carried out after completion. When the car is too close, the rear-view mirror will give a warning. In many cases, it is quite practical, and can play a certain auxiliary role.
Although lane keeping is also a practical function, it can only be started at 80km/h, which means that there is no condition for testing in urban areas. However, you can never rely on these additional functions. After all, the best protection is still the person holding the steering wheel.
summary
In general, as a car owner, I am satisfied with the M1 intelligent rear-view mirror produced by "70 Mile". It is equipped with many functions I need, and all of them are well done. The appearance design is also outstanding, and it is an expert in all aspects. In addition, the author likes the installation method without broken wires, and can easily switch back to the original rear-view mirror.
There are also many functions that have not been mentioned, such as storing videos on the SD card, the body and the cloud immediately after being hit, or the streaming media function that comes with it, M1 has very high playability, which can be explored slowly, but it doesn't matter. Anyway, it has all the most important functions, not to mention the voice command with high recognition rate, which liberates the hands of the author who has been driving for 4 years: - D
