How to Configure Exposure and Backlight Settings

It's recommended to leave the two settings by default. If you feel the image is overexposed/underexposed, with image problems like too bright, too dark, smearing, or noisy pictures, you can try to adjust the two parameters to see if the image quality could be improved.

1. Settings of Exposure and Backlight

Settings of Exposure:

Exposure adjusts the amount of light captured by the camera, optimizing brightness and clarity in both dark and bright areas of the image.

Settings of Backlight:

Backlight​ will optimize brightness and contrast levels to compensate for differences between dark and bright objects.

1. Off: There will be no backlight compensation for the image.

2. Backlight​: The image will be lightened up if you slide the value higher. And the contrast between the bright parts and the darker parts will be optimized.

3. Dynamic Range: The backlight will be compensated dynamically according to the range you've set.

Take the interface of the Reolink Client as an example:
