•
AF/AI when PTZ - Auto focus/iris will activate when PTZ is used, can be switched off. Default is on.
•
Fast Shutter - Select fast shutter is using the Predator-DV camera on a ANPR system. Default is off.
(See page 58 for table of options).
• Near Focal Limit - Can be used to set the near focal limit. This will help in scenes where the camera
is focusing on objects near to the camera, causing the camera to be out of focus on distant objects.
Default is 4m.
• Steady Shot - Can be used to reduce camera shake from the picture.
Steady Shot – The viewed picture is made from a window which shows part of the full picture from the camera
sensor. This means that part of the picture is wasted. The viewed part of the picture is moved automatically
to use some of the wasted part so that the observed picture is stable and has compensated for the vibrations
and minor movements of the Predator-DV. The maximum amount of picture stability is achieved for all zoom
settings. The part of the picture that is wasted reduces the resolution of the viewed picture when the camera is
set to 1080P and steady shot is selected. When the camera is set to 720P it is usual for no resolution to be lost
when steady shot is selected.
Stable Zoom – In this mode, when the picture is zoomed fully out (wide angle) the steady shot feature has no
effect. As the picture is zoomed out the effect of the vibrations is naturally minimized. As the picture zooms
in, the part of the picture that is viewed is a window within the whole (unzoomed) picture. The unused part of
the picture is used to allow the viewed part of the picture to be moved automatically to compensate for the
vibrations. In this mode, the viewed picture has full resolution for all of the zoom range, but the camera does not
compensate for the vibrations when the picture zoom is at or near to the fully zoomed out setting.
Extended Zoom – This option doesn’t produce a steady picture, instead of which, a window within the whole
picture is viewed i.e. the scaling of the picture is altered slightly which gives the advantage that the normal 30x
zoom has been extended to 36x zoom. This is effectively a digital zoom and as such, when 1080P is used, the
resolution of the picture has been slightly reduced. When the camera is set to 720P it is usual for full resolution
to be achieved for the full range of zoom settings.
White Lights
• White Lamps - Set if white lights are to be used.
• White Timer - Set white light timer.
• White Exclusion - Option to be used if a white light exclusion area is to be used, set area using
presets 151 (left) & 152 (right).
• Auto Dimming - When selected the camera will reduce the lamp power, when looking in scenes
where there is to much light.
Night Settings
• Night Changeover - Night Changeover settings can be changed to suit the site requirements. Options
are dark, medium, light and custom. Default is dark.
This sets when the camera goes into ‘dark
mode’.
• Custom On Level - Range is 7 to 25. A lower value will set the level on when the scene is brighter, a
higher value will set the level on when the scene is darker. Default is 7.
•
Custom Off Level - Range is 1 to 20. A lower value will set the level off when the scene is brighter, a
higher value will set the level off when the scene is darker. Default is 1.
•
Night Brightness - This controls the exposure compensation, by artificially brightening the image.
Options are normal and auto. Default is normal.
• Night Illumination - Choose which type of light source is required for when the camera is in dark
mode. Options are IR or white light if supported by the camera.
• Night Intensity - Set what power the lamps will run at. Default is 100%.
• Night Sensor - Can be set to colour or mono. Default is mono.
• Night Focus Range - Sets how the camera will focus (when in mono) to suit the light source in the
scene. If this is set incorrectly the image may not be in focus.
• Night Focus Sensitivity - This can be set to normal or low. When it is set to low the method used to
focus the camera is suited to low light conditions. Default is low.
• Night Aperture - Can be used to increase the picture detail. Default is 3.
• Night Noise Reduction - Used to reduce noise with scenes of low illumination. NR must be set to suit
the environment. Default is 1.
•
Night Presets - This can be used to set the presets to different settings if required. Default is on.
