what dash cam should i buy

Today, let us talk about how to select the dash cam. We all know that the dash cam is like a “black box” on the car. A camera placed on the car can record every thing during driving. In the event of accident, easily judge responsibility. Sometimes encounter a racketeer, these photos taken can be used as evidence. some videos taken by some dash cam in bad environment can help police to obtain evidence. Besides, it also can record the scenery along your way as memory.

The dash cam, a electrical product, has a great progress in this technology time. The dash cam with only 480p or 720p before has developed to 1080p, 1296p or 4k, single function dash cam has developed to the dash cam with WiFi or APP connection and other function. And the price is different from two hundred to one thousand. Facing the various function dash cam on the market, how do we select?

Size: select a dash cam for your car. The best installation of the dash cam is between interior mirror and front windshield. Because the angle not only has clear image, but also don’t affect the driving vision. In practical, due to the different size interior mirror and different position, especial some car with limit space, it is very uncomfortable that install a big dash cam for your car.

Lens: according to the number of the lens, the dash cam is divided into single lens, dual lens and multi-lens. Single lens is common to record the information front of the car. Dual lens is to add a camera on the rear of the car to record the rear information. Multi-camera is for some careful drivers to know the information around their car. According to different type of display, one has a screen, this product generally is big, so when you select this type, you also pay attention to the solution of the screen. In addition, anther is rear-view image. you can change or install on the interior mirror, not only dose it has the function of interior mirror, but also display the recording image, which have an effect on the rear-view function.

Although the dash cam also can be installed on the front windshield, it will affect the driving vision and the shooting angle is bad. So i recommended that, without other factors, you can select the small dash cam, which is convenient to install and ensure the driving safety. In general, the private car needs only a single front camera is enough. Adding rear or side of the camera, on the one hand, will increase the cost of wiring, the other hands will have a lot of information. If the picture is displayed in real time through car navigator, it is more likely to cause the driver’s attention to be distracted.

Second, quality of the image
A “black box” is to restore the scene of the accident, so its value is due to the clear image. About the lens, some dash cam is low than 1 million pixel, and some is more than 10 million pixel. In practical use, users don’t require high pixel and resolution, after all a dash cam is not like a SLR, in general more than 2 million can meet the requirement for shooting clear licence plate number.

Some products have a good effect in daytime, but at night, in low light, the image will be blurred and noise. some workmen in city always drive the car on rainy day or at night, so you should focus on the night vision effect in selecting the dash cam.

In addition, some dash cam although have good effec a in the good light environment, when there are no streetlights or in and our of the tunnel, the light is too weak to get a clear pictture and there places are dangerous areas. Night shooting should taken into account not only that there will be no glare overflow, but also that the shooting can be clear under the condition of weak light. In the case of serious hardware homogeneity, this will test the ability of the R&D team to adjust to the software.

The camera with high pixel can obtain high quality image. In selecting, users can use other digital device, such as digital camera, mobile phone, etc, to compare the dash cam and digital device image. About the night vision, the number of the LED doesn’t represent the ability of the night vision. You can use it to record the same image in daytime and night, and compare. If the licence plate is not clear, the ability of night vision of this product is limited.
