In recent years, the dash cam has become a must-have item for buying a car. The function of the dash cam is mainly to obtain evidence when an accident occurs, to prevent malicious touches, and so on. When you are ready to choose online, you will be confused by the professional terms of 4K panoramic ultra-clear, 2K, and 1080p.

What do these seemingly incomprehensible numbers mean? With so many dashcams on the market, how do you choose? Jimi IoT will answer for you~

Is the Dashcam pixel resolution bigger the better?

First of all, let’s take a look at what pixels and resolution are.

A pixel is a basic unit that constitutes a digital unit, and its full name is an image pixel. The screen of any digital image is composed of pixels. The resolution is simply the number of pixels displayed.

We usually say that the dash cam has a resolution of 1080p, which means a resolution of 1920×1080, which means that the number of pixels in the horizontal direction is 1920, and the number of pixels in the vertical direction is 1080.

Currently, the mainstream dash cams on the market have a resolution of 1080P. This resolution is enough for shooting road conditions.

A higher resolution means that the recordable time of the memory card will be shortened and the service life of the memory card will be reduced. At the same time, it also means higher prices. If you are looking for cost performance, the 1080p dash cam is the best choice.

Is the wide angle of the Dashcam bigger the better?

In order to record more information, the dash cam uses a wide-angle camera. However, due to the characteristics of wide-angle cameras, distortion will inevitably occur. The wider the wide angle, the greater the distortion.

Usually for private cars, the wide angle of 120°-140° is the best balance between clarity and visibility.

Which one should I choose for a dash cam with or without a screen?

At present, many dash cams are equipped with WIFI functions, which can be connected to mobile phone apps to view video playback at any time. Whether such a dash cam has a screen is not so important. In addition, the screen resolution of the mobile phone is much higher than that of the dash cam, and it is clearer to view the video on the mobile phone.

A dash cam with a screen has the potential to distract drivers. And because the volume is relatively large, it has a certain impact on the driver’s field of vision.

These purchase points of dash cam

In fact, compared to the parameters advertised by the merchants, you may have overlooked these key points of the dash cam.

1.What chip and processor does the dash cam use?

The brain of the dash cam is the main control chip. The stability and durability of the dash cam depend largely on the way the chip is packaged and the nominal temperature. If the dash cam is unstable, it may fail within a year. The key evidence was not recorded due to a fault, and the dash cam lost its meaning of existence.

2. How to install the dash cam

Most dash cams get power through the cigarette lighter (as shown in Figure C below). The disadvantage is that the parking monitoring function cannot be realized. The other is to take power from the fuse box (as shown in Figure B below). The disadvantage is that the wiring operation is complicated and requires professional installation.

3. Is the dash cam resistant to extreme heat and low temperature?

This is a point that is easily overlooked when purchasing a dash cam. After being exposed to the sun in summer, the temperature inside the car can reach as high as 70 degrees, and in extremely cold regions, it can reach minus 30 degrees in winter. In high temperatures and extremely cold environments, ordinary dash cams are likely to malfunction.

Jimi dash cam can keep working stably in the temperature range of -20℃-65℃, which is enough to deal with extreme temperature conditions.

The above are the questions that you may encounter when buying a dash cam. I hope reading this article will help you avoid detours when choosing a dash cam.
