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 fram 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. Widen the intervals between the pixels in the
original signal according to the magnification, and then filing 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
In the line lock mode, the AC power supply and vertical sync signal of the cameras are
synchronized.
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.
