5-6-1-1 Line Frequency
Line Frequency is the function that adjusts the shutter speed options to match with
the frequence of artificial light source of given country. For example, in Europe the light
frequency (due to power supply frequency of lights) is 50Hz, that is 50 flashes per
second. By setting line frequency to 50Hz in such case, the shutter speed options will
be proportional with light source frequency, such as 1/25s, 1/50s, 1/100s, etc.
It is necessary to have the camera
’
s Line Frequency adjusted according to the
power frequency of the light source to avoid flickering effect.
The natural light source (sun light) is a seamless flow of light

setting does not matter for the cameras that are only exposed to natural light.
5-6-1-2 High Frame Mode
High Frame Mode (available in non-Hemispheric cameras only) allows users to select
the resolution with 60fps frame rate, where some video settings such as Exposure and
White Balance, etc. will be automatically configured. This configuration will be set as
the video stream 1 and the original configuration of stream 1 will now be video stream
2 and so on.
When any of the settings on this page have been modified, click the Apply button and
reboot to make the changes effective.
Note:
High Frame Mode is enabled only if Rotation is disabled.
5-6-1-3 Rotation
Rotation (available in non-Hemispheric cameras only) allows the camera view to rotate
90
°
or 270
°
. Also known as the
“
Corridor
”
view, rotation provides longer vertical viewing
angle where farther objects can be seen with more details, while the horizontal viewing
angle becomes narrower. This function is useful when installing the camera along
corridors or pathways. Examples are shown below:
Rotation: Disabled
Rotation: 90
