Secondary lighting effects and background motion can pixelate unintended parts of the image. This behavior depends on the scene and the level of illumination.

Fire and smoke

Fire and heavy smoke are pixelated.

Colorized pixelation can obscure fire and smoke. To ensure physical safety, it is strongly recommended to turn off Privacy Protector™ in emergency situations, such as a fire alarm.


Due to necessary illumination, foreground objects might cast shadows that darken or sometimes alter the color of parts of the image. These foreground shadows are pixelated.

Static shadows cast by background objects are incorporated into the background model and are not pixelated.


Privacy Protector™ treats the reflection of a foreground object as a deviation from the background model. These reflected objects are pixelated, which can help ensure privacy when the reflection contains identifying characteristics, such as a face in a mirror.

Moving background objects

Moving objects in the image background, such as trees or clouds, are partially or totally pixelated.

Sudden lighting changes

If image brightness changes significantly, because one or more light sources fail, or are switched off, the areas of the image affected by the change are pixelated until the new conditions are incorporated into the background model.
