With the continuous improvement of living standards, cars have gradually entered every family. However, the reality is not what we imagined. The congestion of roads and the bumping of porcelain on the street are the biggest headaches for new and old drivers. Although the author has had a driver's license for many years, he has really owned his own car for less than a year, which can be said to be a new machine. Therefore, the traveling recorder has also become an essential tool of its own.

I also suffered a lot from the DASH CAM. I didn't understand anything when I just picked up the car, so I installed an ordinary recorder in the 4S store. It has no special functions except video and photo taking. The high price of 800 yuan makes me angry. Recently, the author Love to play computer games The trial platform is particularly lucky to get the experience opportunity of Xiaoyi intelligent rear-view mirror (pilot version). Next, let's experience the practical effect of this DASH CAM.

The author is no stranger to Xiaoyi's products. He has played with Xiaoyi's intelligent camera before. This experience's DASH CAM is also an intelligent version with 3G Internet access function. This model is different from other tachographs in that it is a rearview mirror version, which is relatively convenient to install.

In terms of accessories, Xiaoyi Smart Rear View Mirror Pilot uses the adapter of the cigarette lighter to supply power. This has the advantage that the original circuit in the car does not need to be changed, so you don't have to go to a professional service store to install it. You can do it yourself by pulling it. In addition, we can see that its GPS navigation module is external and can be glued to the glass when using.

The pilot version of Xiaoyi intelligent rearview mirror is 315mm long, the size of its operation screen is 6.86 inches, and the main resolution of IPS full touch display screen is 1280 x 480. At first, the author was worried that the rearview mirror was occupied by intelligent images. How can I check the scene behind? Later, I learned from my experience that its screen is invisible and will not affect normal viewing in standby mode.

The 140 ° wide-angle lens used in the pilot version of Xiaoyi intelligent rear-view mirror allows a wider view, not only the front record, but also the roadside street view. The lens can rotate in a small floating direction according to its own needs, and the camera's pixel has reached 200W, which can record 1080 30 frames and 720 30 frames of video resolution. Although it is inferior to mainstream smart phones, it is enough for driving video recording; In addition, it is equipped with a large aperture of F2.0 as standard, which also increases the light effect and is helpful for night recording.

The commonly used tachographs are automatically turned off when the car starts, but some models still do not support this operation. Therefore, the pilot version of Xiaoyi intelligent rear-view mirror is also equipped with a switch button, but it is designed at the bottom of the body, which the author did not find at the beginning.

In addition to MIC at the bottom, other interfaces are basically on the top of the rear-view mirror. The power cable interface is MINI USB. In addition, there are video input ports, SIM card slots, TF card slots, and GPS antenna interfaces; During the experience, I found that this video input is not available at present. The author also consulted after-sales and said that the corresponding product will be realized in the later upgrade.

Speaking of 3G function, Xiaoyi Smart Rear View Mirror Pilot uses Xiaomi's professional Unicom 3G network card, which may have restrictions on other traffic cards. In addition, its wireless function is limited to hot spot use, and it cannot connect to the WiFi network at home. In daily terms, the 1G traffic is enough for positioning and navigation. Frequent video transmission may be a bit tight, so you can recharge the traffic according to your needs.

The author has installed a recorder for the rearview mirror version before, so it saves a lot of time in wiring. Plug in the original power supply line directly, and then it can be used. When you start the car, the pilot version of Xiaoyi intelligent rearview mirror will automatically power on, and there is no need to start it manually.

Since this tachograph is an intelligent product, it is necessary to say something about the hardware. It adopts MediaTek 4-core A7 processor, with the main frequency of 1.3GHz. In terms of performance, it can support 1080P high-definition video recording, and can be used for a long time; In terms of energy conservation, although it is started with the on-board power supply, a 600mA lithium ion polymer battery is also built in for emergency use.

Let's talk about its intelligent system. Xiaoyi Smart Rear View Mirror Pilot uses the customized YunOS for Car system. The entire APP and operation mode are somewhat similar to our smart phones. Even new drivers will soon become familiar with its operation. Of course, the driving record function is also automatically turned on when the machine is turned on. Unless it is turned off manually, it will record a video clip every hour and store it on the TF memory card.

Although it is an intelligent device, we cannot always stare at it when driving. Therefore, in addition to the video playing software, it mainly has built-in Goddard Maps, Bluetooth call, Xiami Music, Himalayan FM, WeChat assistant, weather, browser and other software. Among so many softwares, what the author often uses is Gaud Map. Through 3G network, he can lock the current position, then tell his destination, and automatically provide several destination answers. After the destination is confirmed, the planned route will be automatically generated.

Let's also talk about the navigation map. Although the central controller of the author also has a navigation column, it is seldom used. Because it has no connection to the network, it has to go to the 4S store to complete each upgrade, and there is also a charge. So the Gaud map on my mobile phone has become my main navigation tool; Now, with this smart rearview mirror recorder, I don't use my mobile phone anymore.

In the experience, the author found that the signal is not very stable in some remote places, so the positioning is not so accurate. However, in the case of no network, the route can be synchronized through mobile phone intercommunication, which is much better than other recorders.

The biggest highlight of this recorder is that it can be controlled by voice. Just say "Hello, Ant", and it will automatically turn on the voice control function. Then say the APP you want to open, and it will automatically jump. You can directly say "I want to go to the railway station", and it will automatically open the map, search the location of the railway station, and wait for confirmation. In addition, it can voice query the weather, take photos, lock videos, close/open the screen, play music, volume, and so on. This kind of intelligent play is like Apple's Siri.

I talked about a lot of intelligence. To be exact, practicality is the king's way. The author opened the driving video camera and took a look at the full screen. The speed is not too fast and the screen definition is acceptable. Next, let's look at some records transferred out by ourselves:

When driving on the street, pedestrians and electric vehicles are everywhere. In addition, if there is traffic jam, you must be careful when driving, and also avoid scratching. In this respect, the pilot version of Xiaoyi intelligent rear-view mirror performs well, and the 140 degree solution can clearly record the form in front. The recording through glass is not bad, and its color is also quite real.

Speaking of clarity, the performance of the ants is regular. There was a slight noise when recording the front license plate, but the license plate can still be seen clearly. Of course, it may also be due to the weather here. Another is after 6 p.m.

The video recorded at night is smooth, but noisy. Good people can see clearly. The most important thing is to see the objects in front. It's better to record the front license plate.

Another highlight of Xiaoyi Smart Rear View Mirror Pilot is its APP management. The ordinary tachograph pulls out the memory card when retrieving the video, and then operates it on the computer. The Xiaoyi Smart Rear View Mirror Pilot has made great changes in this regard. It can be directly transmitted to the mobile phone via the network hotspot, and its speed can reach more than 3M/s.

In addition, AAP has some data for us to check, such as mileage, speed, current parking position and driving safety, which can be checked on the mobile phone.

summary

After more than a week's experience, Xiaoyi's intelligent rearview mirror pilot version generally performs well, which is much better than my previous recorder. It can not only record every trip normally, but also realize various intelligent operations through voice. Especially, when planning the route during driving, you can use it to locate where you want to go. The system provides convenience for users, and all operations are very simple, especially the realization of language manipulation; In terms of recording, the speed is good, and the frames are not jammed, but the clarity at night needs to be improved;

The author also puts forward several points for improvement: this recorder has no rear view record at present, and those who pay attention to the rear view may have to wait for the future upgrade; Although 3G traffic can meet the normal navigation use, it will consume a lot every time the video is downloaded to the mobile phone. It would be better if the mobile phone can be transmitted via Bluetooth.
