Exposure is very important aspect in your dashcam as this decides the colors are captured accurately leaving no details out with proper lighting in short, we can say exposure refers the amount of light captured in a shot.

As the car moves along forward there would be different lighting conditions it has to come by, thereby the dashcam you are carrying in your car should be efficient enough to adjust itself to the varying lighting conditions.

The dashcam’s exposure setting has to be set accordingly as exposure affects the video quality, as in when the exposure goes to high the image or footages gets overexposed whereas when exposure is too low the footage or the images gets underexposed and you lose out on the details that might be great requirement.

So, exposure has direct influence on the video quality.

What is the exposure setting on a dashcam?

Exposure values is what measures dynamic ranges in your dashcams.

So, when the exposure value increases the amount of light entering the dashcam also doubles and when the exposure values decrease the amount of light entering the dashcam gets halved as well.

Usually, the dashcam comes with option such auto, daylight, night, and manual modes these modes are there to adjust the camera to brightness, saturation, and contrast.

It is recommended to use the manual mode at the time of varying lighting condition as this can improve the overall video quality with no details that can get missed out due to overexposure or the footage getting underexposed.

By using the appropriate setting on the dashcam in respect to the exposure can get you footages that are crisp and clear that function as concrete evidence for collision or accident claims.

What is EV setting on dash cam?

These are EV settings in your dash cam, they are important in giving you good quality footage as the EV decides the amount of light entering the camera sensor, these are the settings:

Automatic Exposure-In this setting the dashcam does the adjustments of exposure automatically based on lighting condition the dashcam get exposed during the driving time, here the adjustments are done with no assistance from the driver.

This is not usually recommended as much as manual mode setting due to the fact which with this mode there is less control over the settings and this mode does not always have to provide you with high quality footages on its exposure to varied lighting scenarios.

Manual Exposure -In this setting the adjustments are done by the driver based on what lighting condition the driver encounters, here there is chance of adjusting the settings manually in the case of low light, the exposure value must set in a way your dashcam captures footages with no details missed out.

What is the best setting for a dashcam?

The dashcam video quality is based on pixel count higher the count greater would be the video resolution you can go for 1080P which gives excellent video quality which matches to phone and laptop resolution as well so when the footages are transferred to these the resolution would gel well.

The 1080P video resolution with 30fps will give you footages of great quality from day light as well as night time, and going for higher frame is not recommended as it can lead to loosing of details in low light conditions.

What is the best aperture for a dashcam?

Aperture refers to an in a camera’s lens sensor that allows the amount of light entering the sensor and how it works is that the more wider the aperture is more the light enters the sensor whereas narrower aperture could less the amount of light entering and the aperture is represented by f.

A lower f is recommended as it improves the clarity as the light entering will be more and at low light conditions wider aperture is better.
