subjects are in the same scene, overexposure in the high-brightness subjects or loss of
dark detail in the low-brightness subjects may occur. WDR combines the two images to
eliminate over exposure and loss of detail.
EHLC(Excessive High Light Compensation)
Brings excessively high-brightness subjects into focus.
Mask
Hides one or more areas that the user does not want to be displayed on screen. Masks
can be set with their own display area, color, darkness and mosaic processing.
Detection
Detects motion within the scene using one of the available methods. Some methods
trigger the Alarm output.
Sharpness
Reducing this parameter adjusts the noise level to smooth out the "noise" caused by the
compression.
Caution should be taken not to reduce it too much, which may result in a blurred
image.
Resolution
Controls the display fine details. The higher the resolution, the higher level of details can
be seen.
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 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.
