2.2. FUNCTIONS
Day/Night Function
The cameras features an in-built, automatic Infra Red cut-out filter that switches the output from colour to monochrome in
low light conditions. This enhances the clarity of the image in low-light situations and provides clear video images in
illumination levels as low as 0.01 Lux. This feature can also be activated or deactivated using dedicated commands.
Save/Call Preset
Preset Positions are ‘Memory’ positions that are stored within the camera. There are 256 memory positions available to
the user. The user simply drives the cameras pan, tilt and zoom position and then stores the position in a dedicated
‘Preset’ position, which can be recalled at the touch of a button when required.
Zoom control
The camera features fully controllable optical and digital zoom controls, to a magnification level determined by the
particular model (x18, x28 or x36).
Focus control
System defaults to Auto Focus mode, that is, the lens and camera will automatically adjust the focus to get the best
image depending on the current field of view. This is an extremely powerful feature and rarely (if ever) requires manual
intervention.
Focus can also be controlled manually from the controller if required. Press Focus Near or Focus Far key to manually
focus. Focus can be manual via keyboard or other controller, please refer to control keyboard or other controller
operation manual for detailed operation.
The camera will NOT auto focus in the following situations:
Target is not in the center of image
Targets extend through the near and far depth of field
Target is a strong light source (such as spotlight)
Target is behind glass or there is a build up of water drop or dust.
Target is moving too quickly
The target occupies too much of the image (such as a wall)
Target is too dark of vague.
IRIS control
System defaults to Auto IRIS.
The Camera adjusts immediately according to the alteration of back ground illumination so that a steady image contrast
can be achieved.
You may adjust the IRIS via the controller to get required image brightness if necessary, depending on your controller,
and call back Auto IRIS when required.
Auto White Balance
Camera defaults to automatically adjust the white balance (WB) according to the alteration of background contrast to
give a true color image.
Back Light Compensation (BLC)
If a bright backlight is presents, the subjects in the picture may appear dark or as a silhouette. Backlight compensation
enhances objects in the center of the picture. The camera uses the center of the picture to adjust the IRIS. If there is a
bright light source outside this area, it will ordinarily wash out to white so the camera will adjust the IRIS so that the
object in the sensitive area is properly exposed.
Auto Cruise
Preset positions are programmed to be recalled in sequence. This feature is called auto cruise.
