In order to let more members of drivers know the dash cam, use it correctly, reduce some trouble, according to my experience, I would like to talk about the seven points of the dash cam, hope it can help you.
The bad clarity of the dash cam
Many drivers will ask the following question in their use:
1, I can’t see clearly the license plate more than ten meters.
2, it is difficult to see the license plate in fast driving.
3, I can’t see clearly the license plate next to it at night.
Why do we have this doubt? Actually, in order to promote sales, many businesses will exaggerate their product functions, such as their product resolution reach 1080P, or their master chip cannot meet the requirements, will seriously affect the quality of the picture. Therefore, in the purchase of dash cam must be optimistic about its master chip is what. Now the best effect should be the Ambarella chip, but its price will be relatively high.
Does the dash cam can see clearly license plate more than ten meters? Hardly any! The dash cam price is around 1 thousand or several hundred. Unlike professional video DV, the dash cam is required to see clearly license plate 6 to 7 meters, it can provide the evidence for traffic. Those who claim to be able to see more than ten 20 meters away license plate, which is exaggerated propaganda, but clear 10 meters away from the signpost instructions or can!
the poor effect of the night vision
A lot of users thought that the light determines everything.
Before HDR become popular, shooting in the dark was not ideal and the resolution of the dash cam had to be taken into account. The chip of the dash cam night vision is like to CPU of the computer, the better CPU has a better running function. At present, Ambarella chip has been out to the A12 is the highest configuration on the market, and the effect is indeed more ideal.
The limited power of the dash cam battery.
Most of the dash cam on the market have built-in batteries. We have a mistake on the battery, though that the battery is the main power supply. The built-in battery is like a fire emergency light, which only provides emergency lighting during power outages, and it will not take long to run out of electricity that is normally stored. So the internal power of the dash cam cannot be like a mobile phone, camera which can be standby. Because it is designed to take the car as the main power supply, there is no need to store a large capacity of electricity.
How to wire buried cable
because of the wider visual and no effect on the driving vision, Installing near the interior mirror and front windshield as follow:
It needs longer charger cable to convenient wiring. If the cable is not long enough, you only place the charger cable on central, which has a big effect on the beauty of the car and also bring some trouble for driving.
Wiring to the right door, users can wire the charger cable from the lowest to the top of the car charger, also connect the car charger through the right glove box, both methods can bring the beauty for cars. The cable clips and long charger cable can ensure the best shooting angle, at some time, bring the beauty of the car interior environment.
How to set the loop recording
The recording time of the dash cam directly depends on the capacity of the TF card, image clarity, and the video format. 1080p image occupies 200MB every minute. The different machine has the different parameter, special format. There is three formats of the video can be chosen, such as 1080p, 720p, 360p. in general, a 32G memory card can record about 3 hours.
At present, most of the dash cams have loop recording, it means that don’t be set, automatically cover. When your memory card is full, the dash cam will start to record the most previous video. But the dash cam with motion detection will lock the video.
Is the all-in-one machine good?
there is a lot of dash cam with all kind of function. Because if you want to install an E-dog, navigator, dash cam, it not only affects the beauty but also the wiring appears a lot of problems. After all, the car space is limited.
We all know that each function has the signal interference, up to now, this problem can be solved.
The dash cam can be bought at what price?
The dash cam price has an obvious difference, because of the functions, material, package. But the image quality is the only standard of the dash cam.
In general, the dash cam is about 5 hundred. Two hundred product might use the oldest technology, and the effect is poor. And the one thousand yuan dash cam is sold by the brand
value, which means that the all kind service and quality is reliable.
