WDR wide dynamic is a special automatic light and light technology.it is able to read the dash cam video infortion and find the brightest and darkest part of the video, and then through the secondary analysis and processing, it can balance in all areas of exposure, reduce a bright screen and enhance the darker picture.

This technique mainly has filmed the video for internal processing, at the same time, the automatic exposure function of dash cam adjust the light and shade of before shooting.

Function of wide dynamic of dash cam

It can improve the brightness of the image automatically to bring the clear image in the low night environment.And in the strong light, it can reduce the overexposed pictures to make it more harmonious nature.

Besides, whether in the sunlight during the day, or a tunnel of the backlight, and the night light reflection, it is good to light reflection and interference suppression to make the image clearly.

Wide Dynamic Range(WDR)

What is WDR? Simply speaking, WDR is the very bright part and the particularly dark part of the scene, which can be seen clearly at the same time. The wide dynamic range is the ratio of the brightest brightness value of the image to the darkest light value that can be distinguished.

When the relative brightness of light or light is low, the image of the camera will appear especially bright or dark. The bright area is due to the overexposure and the dark picture is caused by the lack of exposure, and the visibility and quality of the visual frequency are seriously affected. This limitation is what we usually refer to as 'dynamic range'.

High-Dynamic Range(HDR)

What is HDR? Compared with the ordinary image, it can provide more dynamic range and image details. According to the LDR (Low-Dynamic Range) image of different exposure time, the final HDR image is synthesized by using the LDR image of each exposure time corresponding to the best details, which can better reflect the visual effect in the human real environment.

In general, we take pictures, taking the exposure of the high light area, the details of the dark part will be lost, if the details of the dark part are taken care of, the high light part will be overexposed. In order to solve this problem, we use HDR technology, the Chinese meaning is high dynamic light rendering. To put it simply, a photo contains both highlights and details.


WDR and HDR are two different processing technologies, one is hardware, the other is software processing. As for what kind of a good idea you decide, I am more greedy. If the two can use the same effect at the same time, will it be better? Maybe not. In fact, the purpose of WDR and HDR is the same, in order to make the details of the dark part and the details of the bright part clear in the high contrast. Only the methods of implementation are different. Although it is not very accurate, it can be understood that WDR is working hard on hardware, and HDR is working hard on software.

This can happen if the internal battery is heavily discharged. If the camera has not been used for some time and the internal battery is fully discharged, it may take a few minutes before there is sufficient energy from the power adapter to charge the battery and power the dash camera.

If you wish to check the speed of an SD card there are programs available such as HD Tune which can confirm the data transfer rate. The table below shows expected transfer rates for each class of SD card. Highlighted in red are speeds for the Class6 & Class10 cards recommended for use with common dash cameras.

● Make sure the SD card is compatible with camera.

● Make sure the SD card used is not UHS -Ultra High Speed type (indicated by a number inside a 'U'), as these may not be compatible with the current dash cameras.

● Check whether the fuse in the end of the adapter is not blown. Check the cable for damage, which may have caused the fuse to blow.

● Check 12V power socket on Stop/Start vehicles.

● If you have a stop/start vehicle, amke sure that the 12V power socket does not power down when the vehicle enters stop/start mode. If this happens the dash camera will switch off too.
