We all know the main function of the dash cam is to record the video along the way. When we encounter a traffic accident, it can use as powerful evidence. But many drivers also pay attention the recording sounds function. Some people think this function is necessary, but some think it will privacy infringement so they needn’t this function. Today, let us know whether the dash cam has recording sounds function.

In fact, the dual camera dash cam can be simply understood as a camera, the recording sounds are the necessary basic function for every dash cam. some drivers consulted me, does the dash cam only record the outside sounds rather than inside of the car? I am sure it can’t. he was very disappointed and reply that privacy was not protected.

But I have a good news, this function can be turned off on every dash cam. If you don’t want to record your conversation, it can be turn off. Although audio is often hard to prove, some of the important privacy is more troublesome if it is accidentally leaked.

In my opinion, it is not essential to have recording sounds on the dash cam. the most important things are the clear image, suitable wide angle and saving the important evidence. Of course, many dual lens dash cam GPS on the market is complete and various, according to your need, choose a best one. 

Nowadays after buying a car, friends will basically buy a dash cam, but many people don’t install correctly. Quickly see whether you install a dash cam correctly.

where is the location of the dash cam?

After buying the dash cam, a lot of people find a location in the car to install, but the best place to install it in the front windscreen against the center of the position, in other words, it near the interior mirror in the car, which doesn’t affect the driver's vision, so it is best to install the dash cam behind the interior mirror of the car.

In addition, when installing a rear view dash cam, you also pay attention to and ensure the lens is within the scope of the car wiper. otherwise, when in rain or snow, the dash cam can get anything. You just move the dash cam a little sideways at this time.

The right angle of view taken by the dash cam is that the front scenery appears at less than one third below the screen and the A-pillar is below the two sides of the screen.

You should pay attention to avoid the front windshield on the black particle area for sucker dash cam, so it is easy, not firm, in addition, sucker dash cam will be aging, you can just buy a 3M mount and stick it on.

In order to help you solve this problem, AZDOME launches a hidden dash cam -- AZDOME A305 that don’t occupy the space because of the small size. 

A dash cam is a machine for recording the image and sounds during driving. After installing, it has the ability to record videos and sounds of the whole driving, can provide the evidence for the traffic accident. If you like self-driving, you can use it to record the process of conquering difficulties and obstacles.

It is recording as you are driving, recording the time, speed, position on video, quite “black box”. it can also be used at home to shot the life fun or as a home monitoring, also be a parking monitoring. 

With the improvement of the people’s living standards, we gradually choose the car to go outside, and the dual lens dash cam becomes more and more popular because it can play a lot of roles and rich function, which is an indispensable part of the car. So what determines the performance of the dash cam. 

Firs, the most important hardware is the main control chip that is the program of the dash cam. The chip is mainly done by several large companies, using in 4k dash cam. 

The Second is the PCB board that is a board without components on it and divided into 10 / 8 / 6 / 4 / 2  laminates.the more layers the PCB board is better, of course, the more layers are more expensive, if it is more than six layers of motherboard and the components can be broken, it can be re-welded. But the four or two layers of the plate broken, it is basic not to use. 

The third is the small element on the master leaf that is about four hundred. It includes capacitance, resistance, inductance and so on, which are produced from the different manufacturer, so the quality and the price is different. But the low-end or the false dash cam, it is easy to jerry-cut, resulting in the performance of the dash cam unstable, even crash. 

Of course, the above points are very difficult to distinguish in our actual purchase. So we quickly press the button to detect whether the performance of the hidden dash cam is stable, whether the machine’s response is sensitive, whether there will be a crash. 

Today I briefly introduce the disadvantage and advantage of the three top program in current dash cam industry.  

1 American Ambarella: it should be the earliest and most professional dash cam chip company. 

Advantage: it is stability and ahead of the definition. 

Disadvantage: it is expensive so only use in the single lens 

Taiwan Allwinner chip: it was originally made be tablet chips and solutions. Later, a new division was set up to do the hidden dash cam program. 

Advantage:  dual lens and equipped with Android navigation.  

Disadvantage: poor clarity, and almost on night vision.

Taiwan Nevatek chip: it is a relatively old chip program company focusing on the field of the dash cam. Because of its focus, it has a considerable share of the entire mild-to-high-end market for a dash cam. 

Advantage: the Nevatek 96650 as the representative of the chip, clarity is more objective. Reached the height of 1080P, 30frames. It is very cost-effective. 

Disadvantage: representative 96650 only single lens, the clarity is poor than Ambarella.  

For dual dash cam, Nevatek found that the shortcoming of the Ambarella and Allwinner is a dual lens, so it is in the leading position on the market.

But unexpected Nevatek 96655 was born this time is mainly to attempt to seize the all-smart dual-lens market. At the same time, night vision and clarity will not lose to the Ambarella A7.  

Generally, the hidden dash cam has picture resolution and frame rate FPS, and in general, it is best to set to the maximum of the resolution and frame rate. If you often drive at high speed and the average speed is very fast, you can choose a higher frame rate, but the resolution can be lost.

The dash cam is not a continuous recording, but a piecewise recording, and you can copy a video for retention if you need it, and the 4k dash cam is circulated, it will automatically cover the earliest recordings to record a new video. So you need to buy a too large, 8G or16G is enough.

Some dash cam has G-Sensor, which can sense acceleration and intensity in all directions of the car. Turn on the emergency recording to continue recording the crash brakes or car accident.

If you need to choose to the record that has been saved, you will need to use the emergency recording to protect the video from overwriting. 

If your sensitivity is too high, chances are that it will automatically save it when you go through the speed reducer or jolt, and there are too many protected videos, so it can’t continue to record the video. Therefore, we need to regularly clean up protected video or format storage cards.
