Mirror:
rotate the image horizontally.
Flip
: rotate the image vertically.
Note:
These operations are usually applied when camera must be installed in an exceptional position.
For the example of ceiling installation, camera must be installed upside-down.
Day/Night
Day/Night Mode:
Switch the video images for
Day
(plenty of light) or
Night
(Low light) scene. In default
“Auto” mode,
camera will switch to Day or Night vision according to the light intensity. The Day/Night modes contain
2 actions: switching IR Filter
On / Off
, and image hue
Color / Mono
.
In day mode, the IR filter is switched in to avoid the image sensor from receiving the infrared, thus the
true color image is provided. When camera enters night mode, IR filter is switched off to allow IR
illuminations going into the sensor, thus increasing the images light level. The image color is switched
to B/W (Mono mode).
Night Mode Enhancement
With this function enabled, the better night vision will be obtained. However, the number of FPS may
drop depends on the actual environmental illuminations.
Light Sensor Sensitivity
Adjust this value to change the light sensor sensitivity suitable for various light environments.
Night to Day Threshold
The value reflects the timing switching from night to day.
Day to Night Threshold
The value reflects the timing switching from day to night.
Switch Time
The value reflects the delay time for both ways of day and night switch.
Advanced Setting
AC Frequency:
Anti-flicker setting for environment with fluorescent light sources, image sensor
needs to fit the frequency of light (power) source. For instance, the power frequency is 50Hz for most
European countries, while 60Hz is typically for US. This setting is therefore regionally different.
TV OUT:
Option of NTSC or PAL.
White Balance:
The selections for different lightening condition, which is refereeing to color
temperature.
IRIS Mode:
Enable auto IRIS mode when DC-Iris lens is installed. System will enable auto exposure
and gain control. The default value is set to OFF.
Flickerless Mode:
Flickering can also present in various exposure level. Set
“Flickerless” Mode “On”
to fix the maximum shutter speed (auto exposure control). Thus, the flickers can be eliminated. The
default value is set to ON.
Exposure & Gain Mode:
Select auto / manual Exposure & Gain control mode. The selection defines
the controlling in a range of or fixed value, according to the following two items (
Shutter Speed
and
Gain Value
). The configurations will be limited at selected maximum rates when AUTO mode is on.
Max. Shutter Speed:
Also refer to refer to exposure time. Higher shutter speed is normally applied
under strong light circumstance, so the image won’t be overexposure. Lower shutter speed, on the
other hand, keeps image luminance in low light environment.
Max. Gain Value:
Also refer to the amplification factor for the incoming light. Increasing the gain value
provides a brighter image, but the noises may also be increased.
WDR:
Enable this function for image objects under backlight circumstances.
