What Is WDR On Dash Cam? | Why You Should Choose?

Wide Dynamic Range, otherwise known as WDR, is a camera technology available on some high-end dash cameras that enhances the quality of images in low-light, backlit situations.

This article will explain what WDR is, what it does for you, and whether you should use it.

What Is WDR On Dash Cam?

Wide Dynamic Range (WDR) technology improves picture clarity and color accuracy in scenes with extreme brightness and darkness.
It adjusts to different lighting conditions and balances the exposure, enabling deeper and richer colors to be captured.

A dash cam with Wide Dynamic Range (WDR) can reduce noise and improve clarity for clearer images in low light settings.

With Wide Dynamic Range (WDR), you get clearer pictures when the lighting is extreme. It can reduce noise and improve clarity for clearer images in lower light settings.

A dash cam without WDR, for example, may not be able to capture street lights and shadows simultaneously when driving at night, resulting in either very bright or very dark images.

In addition to capturing details in both areas, the dash cam can adjust the brightness and exposure for a better picture.

Using it, cameras adjust their exposure to different lighting conditions. Taking clear, vibrant pictures in extreme lightings, such as in a tunnel or shadow, requires WDR technology.

In extreme lighting differences, such as driving into a tunnel or a shadow, WDR technology is essential for capturing clear, vibrant images.

How Does WDR On Dashcam Work?

Dashcams with Wide Dynamic Range (WDR) can capture a diverse range of light and dark areas by combining images taken at different levels of exposure.

During a dashcam exposure, two images are captured: a short exposure, which is brighter and captures more details in the highlights, and a longer exposure, which captures more details in the shadows.

As a result of combining the two images, an image is created with a greater dynamic range than would normally be possible with a single image alone.

By doing so, the dashcam will be able to capture details in both the light and dark areas of the image, resulting in a clearer and more balanced image.

WDR, for example, can help dashcams capture details in shadows that are usually difficult to see when driving in low-light situations like at night.

Dashcams would capture images with long exposures, which would reveal more details in shadows, and short exposures, which would reveal more details in highlights.

A dashcam can generate a more balanced and clear image by combining two images, resulting in an image with a more dynamic range than what can usually be captured in a single image.

In summary, A dashcam with WDR captures a wider range of light and dark areas in a single image by combining two images taken at different exposure levels.

The dash cam can capture more detail in both lighter and darker parts of the image as a result, resulting in a more balanced and clear picture.

Tips To Maximize The Use Of Your WDR Cameras

The Video Isn’t Everything

Maximizing the use of your WDR camera can be daunting, but it doesn’t have to be. With the right tips, you can ensure that your video footage will be of the highest quality.

Remember that the video isn’t everything; think about the lighting, angles, and other elements that will bring your vision to life.

A blurry movement:

When using WDR cameras, you should know the potential for blurry movements. This is especially true in low light, or when the camera is capturing fast-moving objects.

To minimize this issue, ensure that the camera is set to a suitable shutter speed and that the lighting conditions are adequate.

Additionally, you can use a higher ISO setting to capture more light, decreasing the need for a faster shutter speed.

Lastly, check the image afterward to ensure that the subject is focused and that no blurriness has been introduced.

Keep your camera’s firmware up-to-date for optimum performance.

Updating your camera’s firmware is an essential part of maximizing its use. Firmware updates can often provide improved performance, bug fixes, and enhanced features.

Keeping your firmware up-to-date ensures that your camera runs efficiently and can help you capture the best images possible.

Many vendors also offer features, such as motion detection and audio recording, that can be enabled through firmware updates.

Which is the Best Dashcam With WDR

In addition to excellent WDR (Wide Dynamic Range), the Viofo A119 V3 dashcam features a Sony STARVIS sensor. With this dashcam, you will be able to capture quality footage under a variety of lighting conditions. A built-in G-sensor activates the recording when an impact occurs, which lets you record in low-light settings.
The dashcam also has a night vision mode to record footage in low-light settings without sacrificing image quality.

As a result of all of these features, the Viofo A119 V3 with Sony STARVIS sensor is one of the best dashcams on the market for drivers who wish to record in the highest quality with the convenience of WDR.

How To Use WDR While Driving?

As a driving tool, Wide Dynamic Range, or WDR, helps improve visibility and safety.

Multiple images of a scene are taken at different exposure levels and combined to create a balanced, high-contrast image.

A WDR lens can improve visibility in bright or low-light conditions.
Depending on the camera and the settings, WDR can also add detail to highlights and shadows. When appropriately used, WDR can significantly improve visibility and safety.

Why Do You Need To Know About WDR On Dashcam?

A dash cam with a Wide Dynamic Range (WDR) is essential when recording your everyday drives. WDR allows the camera to adjust the exposure settings, adding more dynamic range to the image.

As a result, the dashcam picks up details such as license plates and road signs that would otherwise be lost in the shadows. WDR is especially useful when driving in dark or brightly lit areas.

It can also be helpful in situations where the foreground and background are different in brightness, such as in the case of an accident or a problem involving a sudden change in brightness.

Reasons Why You Should Choose WDR Camera:

  1. It improves contrast and clarity in dark and bright areas of a scene due to its enhanced dynamic range.
  2. It can capture more detail in highlights and shadows, more accurately representing what’s in a scene.
  3. When a scene contains both bright and dark elements, WDR cameras provide better visibility.
  4. It is possible to capture scenes with various brightness levels, ranging from low light to bright sunlight, using WDR cameras.
  5. Their reliability and longevity are greater than those of standard cameras.


Should I turn on WDR?

Yes, it would be best if you turned on WDR (Wide Dynamic Range) to get the most effective results from your camera. WDR helps to balance the light and dark areas in your photos, resulting in better contrast and detail.

What is the best setting for a dash cam?

The best setting for a dash cam depends on your specific needs and preferences. Generally, it’s best to mount your dash cam at the top of your windshield, facing forward, and ensure the lens is clean and unobstructed. Additionally, adjust the recording resolution and frame rate to ensure you are capturing the footage you need.

Will my dash cam drain my battery?

The dash cam’s battery can be drained if connected to a 12V adapter for an extended period. When your dash cam is not in use, it is essential to unplug it from the adapter to avoid this issue. This is due to the adapter allowing the dash cam to remain on continuously, draining the battery until it has no power left.

What is the best viewing angle for a dash cam?

The best lens for safety is usually a 150° lens since this angle will provide clear, effective footage for police or insurance agencies. However, a lens with a higher angle would be better if additional protection is desired.
