AXIS M11 SeriesThe device interfaceIf your device doesn’t have built-in illumination, these controls are only available when you have connected a supporting Axisaccessory.Allow illumination: Turn on to let the camera use the built-in light in night mode.Synchronize illumination: Turn on to automatically synchronize the illumination with the surrounding light. The synchronizationbetween day and night only works if the IR-cut filter is set to Auto or Off.Automatic illumination angle : Turn on to use the automatic illumination angle.Illumination angle : Use the slider to manually set the illumination angle, for example if the angle needs to be differentfrom the camera’s angle of view. If the camera has a wide angle of view, you can set the illumination angle to a narrower angle,which equals a greater tele position. This will result in dark corners in the image.IR wavelength : Select the desired wavelength for the IR light.White lightAllow illumination : Turn on to let the camera use white light in night mode.Synchronize illumination : Turn on to automatically synchronize the white light with the surrounding light.ExposureExposure mode: Select an exposure mode to reduce rapidly changing irregular effects in the image, for example flicker producedby different types of light sources. We recommend you to use the automatic exposure mode, or the same frequency as yourpower network.• Automatic: The camera adjusts the aperture, gain and shutter automatically.• Automatic aperture : The camera adjusts the aperture and gain automatically. The shutter is fixed.• Automatic shutter : The camera adjusts the shutter and gain automatically. The aperture is fixed.• Hold current: Locks the current exposure settings.• Flicker-free : The camera adjusts the aperture and gain automatically, and uses only the following shutterspeeds: 1/50 s (50 Hz) and 1/60 s (60 Hz).• Flicker-free 50 Hz : The camera adjusts the aperture and gain automatically, and uses the shutter speed 1/50 s.• Flicker-free 60 Hz : The camera adjusts the aperture and gain automatically, and uses the shutter speed 1/60 s.• Flicker-reduced : This is the same as flicker-free, but the camera might use shutter speeds faster than1/100 s (50 Hz) and 1/120 s (60 Hz) for brighter scenes.• Flicker-reduced 50 Hz : This is the same as flicker-free, but the camera might use shutter speeds fasterthan 1/100 s for brighter scenes.• Flicker-reduced 60 Hz : This is the same as flicker-free, but the camera might use shutter speeds fasterthan 1/120 s for brighter scenes.• Manual : The aperture, gain and shutter are fixed.18
