Fluorescent and high-frequency lighting doesn't produce light in a steady manner compared to natural sunlight. Instead, these lighting sources pulse. For the human eye, this is not discernible as it appears as a steady light.
Cameras, however, utilize a rolling shutter, which means parts of the image are refreshed at different times. This causes the camera to show the variations in light caused by the pulsing characteristic of fluorescent and high-frequency lighting.
What is black banding?
The net effect appears as what's called black banding across the camera's feed. The power frequency from the mains power has a direct impact on the pulsing nature of these lights. Power frequency varies by location, which means that not all locations show black banding. For example, US utilizes 60Hz compared to Europe, which utilizes 50Hz.
What to do
If you see black banding on your camera, try to enable Wide Dynamic Range (WDR).
If that doesn't work, contact Verkada Support. A Verkada Technical Support Engineer can assist you in removing the visibility of this banding on the camera's feed by making the necessary changes to the camera's configuration.
