Camera Controller
The next menu, Camera Controller, takes advantage of the Digital Signal Processor (DSP) in the camera to
adjust functions traditionally relegated to screw terminals or DIP switches.
The options in the Camera Controller menu are:
The S2800e uses fully- and semi-automatic iris control. When autoiris is
on, the Close Iris and Open Iris buttons on a keyboard select the
optimum video level the operator wishes the camera to maintain; in
Nextiva Review, these buttons do not work on some cameras. This is
called the Average Iris Level; it adjusts the iris based on the average
intensity of the entire picture. When autoiris is turned off on the
keyboard, the Close Iris and Open Iris buttons directly regulate the lens
aperture.
Selecting the Iris Levels menu displays a sub-menu allowing the user
to choose settings for Average Iris Level, Peak Iris Level or Keypad
Autoiris Adjust. Average Iris Level is described above and performs the
same setting that the Iris Open and Iris Close buttons do when the
dome is in autoiris mode. Peak Iris Level allows the autoiris to regulate
the iris opening based on the video level (or intensity) of the brightest
objects in the picture. The settings may be combined to optimize each
camera’s ability to react to its location. The Keypad Autoiris Adjust
feature prevents an operator from adjusting the Autoiris level from the
keypad, when disabled, which is the default setting.
Note: The S2800e allows the iris to be switched between auto and
manual in simplex. A temporary message (two seconds)
displays indicating auto or manual iris whenever the iris mode
is switched.
For the 23X or 35X models, the Night Mode Control menu will appear.
This menu allows configuration of the IR (infrared) lens. The IR lens is a
mechanically driven lens that is used to optimize the image at low light
levels or during night hours. When Mode “DISABLED” is chosen, the IR
capability is completely disabled. When one of the “AUTO” options is
selected, the lens senses when the IR filter is needed and will operate
at a low, medium, or high relative light level. When the “AUX6-Manual”
option is selected, the lens is only manually operated using the Auxiliary
6 function. Night Color options allow the image to be black-and-white or
color in low light conditions. When “DISABLED,” it will be in black-and-
white. There is also an option for tuning the IR Frequency Response
for specific IR lighting by choosing a setting of default (normal light),
850 nm or 950 nm. This is used to optimize the video intensity when IR
lighting is used.
