IR: Cameras that are equipped with infrared allow the control of
the camera’s function at night.
On: Activates the night vision mode. The IR cut filter is
removed when this option is enabled. The IR LEDs are
activated and the image turns black and white.
Off: The IR functionality is deactivated and the camera will
always send color images. At night, however, the camera will
not be able to capture proper video.
Auto: In this mode the camera automatically engages the
night vision mode when a certain level of light is reached. The
“Bright” value defines the threshold at which the camera
switches IR mode to color mode. The “Dark” value does the
opposite. It tells the camera at which light level to remove the
IR cut filter and activate the IR LEDs.
The image below illustrates the difference between the IR
mode being on and off.
Left: IR = “Off.” Right: IR = “On” or “Auto”
Note: Standard cameras do not display this parameter; they
display a parameter called night mode, which can be set to
“Auto” or “Off.” Auto means that the camera increases the
shutter time to ¼ second, creating a longer exposure time,
which allows the camera to capture images even in low light
conditions. When set to “Off,” the camera will not adjust the
shutter time and the resulting images are darker.
Overlay: Activate text overlay in
order to display the date
and time information on
the live image of the
camera, along with an
alias name for the camera.
When these options are
activated, the live video
shows the information in
the specified position, as
shown to the right.
