How to choose a dash cam

How to choose a good driving recorder, can reliably record every detail in the process of running, and not wasting money buy a bunch of useless features? The following tips you have to understand.

1, HDR and WDR

What is HDR? In simple terms, it is to fill flash. In the poor environment, if without HDR, the dash cam can ‘t shoot anything. Built-in HDR dash cam can improve the visibility to protect driving at night.

What is WDR? In simple terms, it can see clearly the brightness and darkness of the image. That is a specific value between the signal value of the brightness and the signal value of the darkness.

Most of the machines have WDR, but does it have HDR? At present, expect Ambarella A7 and OV 4689, others are fake HDR. What role does it play during driving? it should be compared. At present, the dash cam with HDR on the market is AZDOME on ivooe.

2, circulate video

Because of the limit of the memory card, and the file of the video is large. At present, 64G only supported by AZDOME with 1080p can achieve 10hours parking monitoring. It deletes the previous video to give the space for the latest video. This circulate video is the basic function to distinguish the original DV and phone recording.

3, track deviation warning and front car movement warming

Both them is a similar principle. It also uses the image to process the image and makes sound cues when it is found that the lane deviates from the lane. These two functions can play a significant role in answering the phone, lighting cigarettes, chatting and getting sleepy.

The moving warning function of the front car is that the vehicle recorder calculates the relative speed of the vehicle through the real-time processing of the ingested video image, so as to get the time when the driver does not take measures. Sound alerts are issued when they are less than 1 seconds.

4, GPS

This list of GPS in 4th is not meant to make more people notice that it is a useless feature that must be used five times a year when you buy the best dash cam with GPS.There is little chance of working. At present, the top product integrated navigation function after the highest definition of the only 720P, product performance does not increase but decline.

Here, I am only collecting the most important and the most basic dash cam selection guide. However, it should be made clear that the functions of the dash cam are not as much as possible. Because many users prefer an integrated machine. In fact, the more function will decline the performance. The dash cam stability will also be reduced, at that time, you should consider its quality.
