2D/3D_NR (Digital Noise Reduction)
Adjusts the illuminance noise level in low light situations by reducing image noise in order to improve
the image. 2D-NR is space-based and 3D-NR is time-based.
Frame Control
Specifies how many frames are generated/transmitted in a unit of time. The more frames there are,
the smoother the image will be. The television system (NTSC/PAL) has adopted 30/25 frames per
second (fps) to be regarded as completely smooth image. However, when recording video data,
video surveillance systems often use lower frame rates to reduce the size of the recording data.
Nega
Reverses the color signals for the
Chroma signal so the image looks like a “negative.”
d-PTZ (Digital Pan/Tilt/Zoom)
Adjusts the camera position and zooms in on a section of the overall full image. The pixels in this
area are then enlarged so the image is the same size as the original, giving the appearance of being
zoomed in. Widens the intervals between the pixels in the original signal according to the
magnification, and then fills these intervals with interpolation signals.
Communication
Allows for the connection to external devices, such as keyboards, through the menu interface.
Iris Control
Automatically adjusts the level of the iris according to changing light levels without having to manually
turn a ring on the lens to open or close the iris.
LLC (Line Lock Control)
In the line lock mode, the AC power supply and vertical sync signal of the cameras are synchronized
to prevent picture roll when switching between cameras in multiple camera installations.
White Pixel
Automatically detects and compensates for peak white levels to maintain the image quality. White
pixels, whose frequency of occurrence varies in proportion to the temperature, are sometimes
observed when the devices are used under the influence of external factors or especially high
temperatures.
Day/Night
Allows the camera to be effective, even in the lowest of light conditions, while still showing clear color
pictures during daylight hours. Day/Night cameras automatically change from color images to black
and white when the light levels drop below a certain level.
