2 Installation
Before you start:
 Make sure that the device in the package is in good
condition and all the assembly parts are included.
 Make sure that all the related equipment is power-off
during the installation.
 Check the specification of the products for the
installation environment.
 Check whether the power supply is matched with your
power output to avoid the damage.
 Make sure the wall is strong enough to withstand three
times the weight of the camera and the mount.
 If the wall is cement, insert expansion bolts before
installing the camera. If the wall is wooden, use self-
tapping screws to secure the camera.
 If the product does not function properly, contact your
dealer or the nearest service center. Do NOT
disassemble the camera for repair or maintenance by

3.2 EXPOSURE
Exposure describes the brightness-related parameters,
which you can set the EXPOSURE MODE as GLOBAL, BLC,
or DWDR.
 GLOBAL
GLOBAL refers to the normal exposure mode which
performs exposure according to the whole image
brightness.
 BLC (Backlight Compensation)
BLC (Backlight Compensation) compensates light for the
front object to make it clear, but this may cause the over-
exposure of the background, where the light is strong.
 DWDR (Digital Wide Dynamic Range)
DWDR helps the camera provide clear images even under
backlight circumstances. When both very bright and very
dark areas simultaneously exist in the image, DWDR
balances the brightness level of the whole image to
provide clear images with details.
3.3 DAY/NIGHT
COLOR, BW (Black White), and AUTO are selectable for
DAY/NIGHT switch.
COLOR
The image is colored in day mode all the time.
B & W (Black and White)
The image is black and white all the time, and the IR
LIGHT turns on in the poor light conditions.
You can turn on/off the IR LIGHT and set the value of
SMART IR in this menu
Figure 3-3 B & W
 IR LIGHT
You can turn on/off the IR LIGHT to meet the
requirements of different circumstances.
 SMART IR
The SMART IR function is used to adjust the light to its
most suitable intensity, and prevent the image from over
exposure. The SMART IR value can be adjusted from 0 to
3. The higher the value is, the more obvious effects are.
AUTO
Automatically switch Color, or BW (Black and White)
according to actual scene brightness.
You can turn on/off the IR LIGHT, and set the value of
SMART IR in this menu.

3. The higher the value is, the more obvious effects are.
 D N Threshold (Day to Night Threshold)
Day to Night Threshold is used to control the sensitivity
of switching the day mode to the night mode. You can set
the value from 1 to 9. The larger the value is, the more
sensitive the camera is.
 N D Threshold (Night to Day Threshold)
Night to Day Threshold is used to control the sensitivity
of switching the night mode to the day mode. You can set
the value from 1 to 9. The larger the value is, the more
sensitive the camera is.
3.4 VIDEO SETTINGS
Move the cursor to VIDEO SETTINGS and click Iris+ to
enter the submenu. BRIGHTNESS, CONTRAST,
SHARPNESS, SATURATION, DNR, AGC and MIRROR are
adjustable.
Figure 3-5 VIDEO SETTINGS
BRIGHTNESS
Brightness refers to the brightness of the image.
You can set the brightness value from 1 to 9 to darken or
brighten the image. The higher the value is, the brighter
the image is.
CONTRAST
This feature enhances the difference in color and light
between parts of an image. You can set the CONTRAST
value from 1 to 9.

SHARPNESS
Sharpness determines the amount of detail an imaging
system can reproduce. You can set the SHARPNESS value
from 1 to 9.
SATURATION
Adjust this feature to change the saturation of the color.
The value ranges from 1 to 9.
DNR (Digital Noise Reduction)
The DNR function can decrease the noise effect,
especially when capturing moving images in poor light
conditions and delivering more accurate and sharp image.
You can set the DNR as HIGH, MEDIUM, or LOW.
AGC
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set as HIGH, MEDIUM,
or LOW. Select OFF to disable the AGC function.
Note:
The noise will be amplified when the AGC is on.
MIRROR
OFF, H, V, and HV are selectable for mirror.
OFF: The mirror function is disabled.
