Since the end of 2011, the dash cam has been recognized gradually. In fact, the dash cam has long been a necessary product in Russia, South Korea, and other countries. In Taiwan, it has also become the standard for vehicles. The domestic dash cam has just started. Users know too little about the products and don’t know how to select at different prices. Here, I give you some advances for reference.

Image quality

Don’t listen to the businessmen and the fake parameter. Like 1280*860 is interpolated by the 640*480. so that it is useless. 720p, called HD, can shoot clear the license plate within 3 meters. 1080p can shoot clear within 10 meters. In my opinion, 720p is enough, similar with DVD. There is a simple method to distinguish the image quality, comparing the size of the two 5 minutes files.

Wide angle

Usually, in the purchase of the dash cam, we will focus on the wide angle. Many people think that the bigger is better and most of the people firm this view.

In order to promote the sales, many businesses continue to exaggerate the publicity, even having 270-degree wide angle. Here I would like to say that the larger wide angle isn’t better. The main function of the dual dash camera is to record clear videos. So it not only requires the high-quality image, but also the entire horizon, but this is limited by the technology.

The deformation of the dash cam is a big problem. As the wide-angle increase, the deformation will more and more serious. In general, more than 90 degrees will begin to deform. At present, the best product in the world only can reach 160 degrees.

Therefore, if the 160 degrees promoted don’t have deformation, it may only about 120 degrees. But some dash cam actually reaches 160 degrees and don’t affect to obtain the evidence. but usually, these dash cam is expensive.

If you want the clear image, you must abandon some vision. The suitable wide angle is about 120 degree to 140 degrees.

Driving on the road, there are some unexpected things occurring. In that time, the dash cam plays an important role. How to choose a high cost-effective dash cam?

Q: Does The larger wide angle of the dash cam have a bigger deformation

A: The common accident happened on both sides of the car, which is difficult to judge the response. So the wide angle is necessary. The reason for the large wide angle is that the fish-eye expands the scope of the vision through the convex mirror, at the same time, it brings some deformation.

At present, the mature technology product adopts full glass lens with 170-degree wide angle, it not only have s strong ability to correct the video but also increase the clarity and minimize blind area and information.

Of course, it is noticed to the fake parameters. Some 90-degree wide angle was promoted in more than 140 degrees.

Q: does the dash cam only need 1080p?

A: At present, the mainstream resolution of the dash cam 1080p on the market. If in 100km/h, it is still impossible to guarantee the shooting effect for license plate and the general situation, more than 1296p would be the first choice.

Q: does the dash cam need a screen?

A: the videos taken by the dash cam without screen need to be played on the computer. If without wifi, once the accident happened, it is troublesome to playback on the computer to obtain the evidence. Therefore, the screen is a standard for the dash cam. If it also can connect to the mobile phone, it is more convenient.

Q: Does the dash cam need 24-hour parking monitoring?

A: A lot of dash cam will automatically power off while the car shuts down. It might happen some unexpected things when parking. So it is important to have a dash cam that can work when some objects or people move within the monitoring range.

Q: Which is better? Dual-lens or single lens?

A: because of the cost, the pixel and wide angle of the dual-lens are low. If the front camera is 1080p, 140 degree, the rear camera must be 720p, 100 degrees. The dual-lens dash cam has a high requirement for the chip. Therefore, the cheap product can’t ensure the stable working. Besides, the front windshield of many cars with a dark film also result in the unclear image.

Q: Is the dash cam with LED night vision good?

A: the accident often happened in the nighttime. Don’t listen to the manufacturer’s promotion. If you don’t know about the parameters, look at the videos taken in the nighttime. People who have used LED lights will know that there is a blind area driving at night, if the LED lights are on in the car, it will probably make more blind area.

Sound Record

Sound Record can record more information on accident, but in daily life, it will record some intimate things, so this function has two sides,

A lot of dash cam can be turned off the sound record, of course, according to your needs, set to protect our privacy.

High resolution

Now, a lot of dash cams are beginning to popularize HD image. At present, entry-level models also are equipped with 1280*720, but the mainstream models are equipped with 1080p.

However, we should distinguish the image quality and the high resolution. Sometimes the 1080p machine is poor than 720p. because these machines expend the resolution by some algorithm, isn’t a true resolution.

Night vision

In order to record clear video, most of the dash cam with night vision. the night vision effect not only is increased by the hardware but also the after- process can improve the clarity through the exposure or adjusting brightness.

Of course, driving in daytime must need the night vision, because the light will change in or out the tunnel, the night vision effect bring more outstanding effect.

Lens

At present, many manufacturers are boasting that the lenses of their home products have a high-definition coating or special processing technology to improve the overall picture quality of the recorder. the lens of the current dash cam will not cause a bottleneck to the overall performance of the dash cam. When we look at lens parameters, we need to focus on whether these parameters can meet our needs, as long as this is enough.

Aperture

Most people know that the aperture of the lens controls the lighting, improving the image quality in low light. At present, the main aperture is F2.8, some are F2.0 or more, combining with night vision, it can apply to all kind of low light,

However, the large aperture is more blurred. In order words, only the focus is clear, anther is blurred. So when in the purchase of the dash cam, don’t choose the small aperture.
