Select INPUT SIGNAL and then, with the LEFT/RIGHT keys, select between signal types HI
and LOW:
HI = The camera switches from day to night mode if it receives a +5V signal at the
input. When this signal is no longer detected, the camera changes back to day mode.
LOW = The camera switches from day to night mode if it receives a 0V signal at the
input. As soon as the camera receives a +5V signal, the camera changes back to day
mode.
Note: These settings do not apply until you quit this program menu.
HI
9.5 Video picture setting (PICTURE)
This menu is used for the perfect setting of the video signal with the help of a video monitor or
oscilloscope. The settings have a strong impact on the video picture. The factory settings are
optimised for 80% of all applications. You are recommended to keep the factory settings. To
change the settings in the submenus, use the RIGHT/LEFT keys to navigate to the desired menu
item and then press ENTER. The following submenus are provided:
VIDEO: Here you can change the settings for the average chroma for improving the colour signal-
to-noise ratio, the colour depth (hue), the brightness, the pedestal (black level), the SPRS effect
and the SPRS gain.
PATTERN: Here you can define a pattern of colour scales to be supplied by the camera to the
monitor via a pattern generator.
APERTURE: Here you can fine-tune the vertical and horizontal lines, thus optimising the picture
clarity.
GAMMA: Here you can make a gamma correction to adjust the camera for different display types
(TFT monitor, tube monitor, etc.). This is made possible by an extended dynamic range with
knee circuit.
