preface

The main reason why human beings are different from animals is that they can use tools. Cars have been used as transportation tools for more than a century. In the days of driving this technological monster, a new problem arises in Song Xiaobao's "Touch Porcelain". Who will protect drivers while ensuring the safety of others!

The DASH CAM, as a sharp tool to crack the driver's freedom from being framed, has also been widely accepted by drivers. The DASH CAM has clear eyes, which can neither be short-sighted nor presbyopia. It can clearly look at the world and firmly record it in the brain.

Today, we welcomed the trial product provided by Ganji.com to stare at the mini2 DASH CAM. They all said that the advertising of the DASH CAM was very wet, so they came to tear his face.

test

The key to the DASH CAM is the image quality. This is the beginning of the opening chapter! The test and comparison are the products with similar prices last year. In order to avoid mutual advertising suspicion, the brand and model are not mentioned here, but the same six optical glass lenses are guaranteed to be used to promote 156 ° ultra wide angle.

The field of vision of the DASH CAM is very important. Is there a legendary 156 degree super wide angle? Most of the camera lenses of the DASH CAM will be exaggerated. Let's check it. It's just a simple algorithm, and there may be some errors! The results tell us that the two right angled sides X=14, Z=10 calculate Y=17.2, sin ∠=0.813, so the angle is about 55 °, 110 ° on both sides, it seems that there is still a 46 ° gap.

And what about today's protagonist? In the same way, use staring at the length of the mini2 shooting ruler, check the visual angle, and the angle is 50.7 °, and the bilateral angle is about 101.4 °, which is also quite different from the publicity. However, according to the diagonal calculation of the screen, there is little difference with the promotion, so most advertisements are calculated diagonally.

The wide-angle lens will have a certain picture distortion. Are there any distortions in these two recorders? The answer must be yes. A good camera will reduce deformation through software. Compared with the above images of the two types of tachographs, staring at the mini2 will bring less distortion!

Both models of DASH CAM have the function of taking pictures, but in different ways. The button mode of Bluetooth connection is used for staring and shooting! With 2K image quality, the image quality of the photos taken is clearer. Although the contrast DASH CAM is 1080P, which has a better image quality, it will also lower its head six months later today.

Working conditions

Test environment: daytime+rainy days. In the daily driving process, there is a picture of small raindrops on the front screen in the video. The light conditions are not the best. The car can not only go out in sunny days. Of course, the recorder can not only be used when the light is the best. Now the performance in cloudy days is also very representative! Gradually approach the car in front, return the picture, check the two videos, you can see that the two tachographs with the same optical glass lens are not very different in image quality performance. Due to the reflection of the front windshield, the video recorded by staring at the camera has suffered a lot, and the comparison video is not clear! However, it can be seen that the brightness of the video is much higher than the contrast!

Test environment: tunnel. When the vehicle enters the tunnel, it can be seen in the two videos that there is no good control over the glare generated by the lamps. In the absence of the best control, it is better than who can control it. For this, the glare control is equivalent, while the contrast adjustment of the staring mini2 is relatively low, making the picture more white.

Test environment: dark night. When driving, there must be road conditions at night. The light at night is very poor. Without good imaging technology, it will be dark and unable to monitor! The night scene of a city is often complicated in light and changeable in light source, which is more challenging for the driving recorder. On the one hand, it is necessary to control the noise, on the other hand, it is necessary to achieve clear picture quality and sufficient light. Take a screenshot in the video to compare the excellence of the two tachographs.

In the video, we can see that more information is recorded in the staring and shooting mini2 pictures, the pictures are brighter, and the details are recorded! In terms of noise control, the two models are similar. In order to get more information, the image quality is sacrificed, which is also the disadvantage of most of the DASH CAM at the same price.

APP

In fact, the style of the two APPs is similar, and the plate functions are similar. What's interesting is that there is a function of uploading and sharing, and interesting and beautiful videos can be shared together!

In addition, everyone can be a law enforcement officer in case of internal reports of violations, and has constantly learned traffic regulations in the process of law enforcement, and always reminds himself to drive according to traffic regulations!

The overall APP has a simple picture, complete classification and classification, and simple operation.

appearance

Some people here may want to have a look at staring, staring and patting. The following focuses on the appearance of staring, staring and patting.

After the box is opened, the layout of accessories is compact, and each accessory has its own protective sleeve, effectively reducing the damage during transportation!

The standard configuration of the staring and shooting mini2 DASH CAM is: staring and shooting mini2 host, remote control, car charger, power cord, installation accessories, etc.

Staring at the mini2 mainframe, the resolution has reached the 2K level, and the sports camera has reached the 4K level, while most of the DASH CAM products still remain in the 1080P capacity. High resolution is the highlight of staring at the mini2, and the resolution beat 90% of other products in the market; Body size 87mm × 35mm × 43.5mm; CPU model: Huawei Hi3516D.

The staring camera adopts a 270 ° rotatable camera. The cylindrical body is designed with a speaker at one end. In actual use, the sound is clear and recognizable when the vehicle is running normally.

The other end is designed with a hidden TF card slot, and the protective cover makes the integrated style of staring, staring and shooting mini2 more thorough!

summary

As an online tachograph, it has the ability to socialize. Through six optical lenses, the mini2 can effectively record the driving information and protect the driver's driving safety! Moreover, as an Internet, it can also share the beautiful scenery during the journey and the strange news during the journey.

advantage:

1. Clear picture quality and good noise control.

2. The 270 ° rotatable camera can take photos inside and outside the car.

3. APP shares in a timely manner, bringing happiness to more people.

Disadvantages:

1. There is no base bracket, which is stuck on the front windshield for a long time, and the glue is dry and unglued.

2. The glare control should be strengthened. The glare is large under the tunnel and night light, and the recorded picture will be blurred.

3. When the light is dark, the noise control is strengthened to make the picture more delicate.
