6.5.2 CAMERA PROFILES
This section selects which set of camera settings to use for the default 'day' and 'night' mode. See the 'Camera Profiles'
section for more information on the use of profiles.
Day Night switching may be performed manually, e.g. via the web interface or by the use of 'special' preset selection, or
according to the camera metered light level.
There are two 'slider' controls for setting the metered light level for switching into night mode, and into day mode.
If these values are set too close together, the camera may toggle back and forth between modes. If set too far apart,
then the camera may become locked into one mode or the other if the threshold value is never reached.
The current metered light level value is reported on screen to assist in setting suitable values.
An additional slider control 'Switching Delay' sets the time for which the light level must be maintained over the
threshold before switching is carried out. This prevents the camera mode from being changed by passing car
headlights, or looking into a dark corridor during a tour.
Capture Framerate sets the video timebase selection for the camera imager. The selection choice is between 30fps
(60fps in high speed capture modes), or 25fps (50fps in high speed capture modes). Generally speaking, 25/50 mode
will be preferably in European installations to eliminate flicker from mains powered lighting, and 30/60 mode in US
installations (where the mains frequency is 60Hz).
6.5.2.1 RESTORE/HOME POSITION
The camera may be set to automatically return to a preset position or commence a predefined tour, if there has been no
manual control input for a period of time.
6.5.2.2 CONTROL CONFIGURATION
The Joystick Speed Scaling control adjusts the overall speed range for pan and tilt operations, both from the web
interface and via ONVIF control systems. This is most useful for onvif clients which don't offer speed adjsutment for
their PTZ controls.
If 'Datum Check' is selected, the camera will automatically check the calibration of the pan and tilt position, and exercise
the motor mechanisms, once per day at a pre-determined time.
This option is useful for cameras where external disturbance is occasionally a problem, or where the camera operates
largely on automatic tour over only a small movement range, to prevent uneven wear occurring in the long term.
PTZ Power Saving mode reduces the power supplied to the pan and tilt motors when the camera is not moving. This
reduces overall power consumption and helps to reduce the internal camera temperature to improve reliability.
In circumstances where external interference with the camera position is likely, then switching off the power saving
feature increases the camera resistance to movement when parked.
6.5.2.3 SHORTCUTS
Selecting a numbered preset as a shortcut activates the named function instead of moving to a defined position.
Shortcut preset settings are provided for the following functions:-
• Wash (Only available with the Alarm PSU option)
• Wiper (if fitted)
• Day / Night Mode Toggle
6.5.2.4 CAMERA PROFILE OVERRIDE
Preset memories can be selected to allow quick access to camera profiles 1-5. Each preset is a toggle action (selecting
once forces a profile switch, selecting a second time returns to normal operation mode).
In addition, a 'Cancel Profile' preset can be selected if required.
