NIGHT→DAY (0-255) Select to set the threshold for identifying the Day status from the
Night status. Lower (Higher) value makes the camera switched from Night to Day at
lower (higher) illumination. If the camera stays in B/W mode during day time, decrease
NIGHT→DAY threshold value until it switches to Day.
EXT1 In this mode way of D&N change is controlled by external synchronization
(photovaristor). EXT1 mean D&N will exchange at high level voltage,
EXT2 In this mode way of D&N change is controlled by external synchronization
(photovaristor). EXT2 mean D&N will exchange at low level voltage,
3.1.8. BACKLIGHT submenu
These compensation functions allow for enhancing visibility of the objects located in the
foreground, surrounded by strongly illuminated background (BLC) or for enhancing visibility of the
objects located near the strong light source (HLC). If a strong, point light source appears on the screen,
function will mask it allowing for effective observation of the scene itself (for example this function is
used to, observe licence-plates of the cars).
3.1.9. ATR (Adaptive Tone Reproduction) submenu (WDR)
The ATR feature improves the dynamic range and the visibility of the image by providing the
optimal gradation compensation of the image in one field. This is achieved by two steps image
processing: luminance compression and contrast enhancement, so that the tone can be enhanced at
highlighted and dark areas.
LUMINANCE (LOW, MID, HIGH) Compresses the highlighted area and enhances the dark area so
that the entire image can converge toward the medium level. LOW will compensate
minimally and HIGH will average out the image. With setting HIGH, the image may
look less contrastive and noise may increase in the dark area.
CONTRAST (LOW, MIDLOW, MID, MIDHIGH, HIGH). Adjusts the strength of the image
contrast.
3.1.10. PRIVACY submenu
This menu allows for enabling four privacy zones. If this option is turned on, desired part of the
screen is masked using rectangular zones. Pressing SET displays submenu which allows for adjusting
privacy settings.
AREA SEL (1,2,3,4/4) Sets the mask frame to be adjusted.
TOP (0-288) defines the upper border of the selected zone;
BOTTOM (0-288) defines the lower border of the selected zone;
LEFT (0-468) defines the left border of the selected zone;
RIGHT (0-468) defines the right border of the selected zone;
COLOR (1-8) Sets the colors of the masking frames.: red, green, blue, yellow, cyan, magneta,
white, black;
