1、Video Solution

Video resolution has been a selling point for manufacturers, from the HD720p, full HD 1080p to Ultra HD 2K, 4K dash cam, the driver is familiar. The general dash cam resolution offers divided into 1080FHD, 720P, WVGA, and VGA.


1080FHD is a full HD resolution, the resolution of the picture is 1920*1080, in H.264 compression format, so recording 1 minute is about 100MB, recording one hour takes up about 6G.

720p is HD resolution, the resolution of the picture is 1280*720. recording 1 minute is about 50MB, recording one hour takes up about 2.5G.

VGA generally refers to 640*480 resolution, while WVGA, 848*480, is the widescreen mode of VGA. Using these two resolutions, the video size of one hour is about 1 to 1.5G, because the low-end product on the market can reach 720p, so the practical significance of these two resolutions is not very great.


How do we choose the video resolution? You should be considered both the size of the memory card and the time of single driving. We recommend that owners choose larger memory cards so that choose a higher resolution format.

Generally, the card below 8G is with 720p, If it is more than 16G, you can choose the 1080FHD. In daily use in urban areas, the resolution can be set to 1080p to get more detailed images, if on a long trip, you can choose a 720p to get a longer recording, which can avoid that your image on the way have been overwritten and you were not arriving at your destination. 


2、Circulate video

The different product will have a different choice. Taking F310 as an example, its provide four choices, off, 2 minutes, 3 minutes and 5 minutes. if the circulating video is turn off, when the memory card is full, the dash cam will automatically stop recording. And if you set 2 or 3 or 5 minutes, the video is cut up pieces of different length for saving.


So how do we choose? If you choose the shorter time, the video will be separated many pieces, which will increase the probability of losing frames. And the longer time set up, it is troublesome when we need to query. So it is recommended that it is suitable to set 3 minutes. Of course, if it is a long journey, it is recommended to choose the longest time to save the preservation of the scenery along the way and other videos.


3、WDR

WDR, Wide Dynamic Range, meaning the range of the wide dynamic, is wide dynamic technology. It can have greater exposure, in high contrast environment, it can shoot more details and more clear. You can set this function if your dash cam has.


4、Motion detection

The popular understanding is that the picture will be automatically recorded in the case of moving, some dash cam will record a few minutes after no moving. There is usually a delay of 2 to 5 seconds from the lens giving instructions to the dash cam.


It is not recommended to open during driving, because of the sensitivity and algorithm, it will lose the frame. This can be turned on for long parking, it can reduce the power consumption to extend the life of the battery or mitigating the impact on the car battery.


5、Sounds Recording

In the case of the sounds recording on, the dash cam record the image, at the same time, it will record the sounds. So i suggest the driver who needs privacy to close this function to avoid some trouble for privacy disclosure. Most of the best front and rear dash cam also provides a one-click shutoff function, which driver can choose according to different circumstances.


6、G-sensor

G-sensor is also known as impact storage. When the recorder's CPU reads that the gravity sensor's value exceeds the set value, the crash is thought to have occurred and the current segment is protected against deletion. In this way, the function of automatic storage is realized when a collision occurs.

General the dash cam gives three options for high, middle and low levels, often accelerating and decelerating and driving bumpy, as long as the recorder is set to a high or medium state, the video is basically saved as read-only. It's all saved and not covered. It is recommended that this feature is turned off to save the video manually when a collision occurs. Most dash cam devices are also equipped with a one-click emergency storage function. 

If you like to turn it on, it's best to set it to a low level, and then format it regularly (depending on the size of the card and the drive you drive each day) so that the memory card doesn't hold too many videos that can't be overwritten. Causes less memory to loop through the video. When a memory card is unable to record a video continuously, or a video is missing from the memory card, check that this feature is turned on.


7、Delay shutdown

Delay shutdown generally provides "shut down, 10 seconds, 20 seconds, 30 seconds" four options, the realization of the function is to stop the power supply (usually the vehicle shutdown) after the dash cam still maintain a period of time video. Generally set to "close" or "10 seconds".


8、Delay starting

Delay starting generally provides "shut down, 10 seconds, 20 seconds, 30 seconds" four options, the function is that after the power supply dash cam does not start immediately, but will delay a period of time to boot.

9、Exposure setting dashcam

Exposure compensation is an exposure control mode, the common exposure range is about: about 2~3EV, if the ambient light is dark, the exposure value can be increased, such as +1EV, +2EV, the clarity of the picture will be compensated. If the ambient light is bright, it can be adjusted to: -1EV, -2EV, it is specific to see the actual picture when adjusting. The situation is determined.


Because most models (especially Japanese and Korean) now supply power to the whole car after the key is turned on, but when the fire is ignited, the whole car is turned off and reconnected. The dash cam is generally powered on will automatically turn on, which will cause the dash cam to turn on twice. By setting the boot delay to avoid this situation, car owners can be based on their driving habits, choose the corresponding options.


When you get on the bus, you usually turn on the switch first, let the vehicle automatically check you, and then fasten your seat belt. When the vehicle self-examination is over, light the fire again. Generally, it is around 15 seconds, so choose "20 seconds" on this option. You don't have to set this option if the entire car remains powered when the car is on fire.
