3.2.4 Night Vision Setup
The camera can be opened automatically when camera check dark environment.
[Infrared LED control] When the environment is dark, the LED will be opened
automatically due to a photosensitive component. Users also can select open or close
the infrared LED manually.
When the environment is dark, the moving images will be [Black and white mode]
changed to Black and White automatically. Users also can select whether change the
images to black and white or color manually.
Boosts the available light by reducing the frame rate to 7.5 fps. [Moonlight mode]
It can be set to “On”, “Off ”, and “Automatic”. This uses the light sensor to turn on
moonlight mode only at night. When “Moonlight model” is “auto” or “On”, the
cameras produce gorgeous night vision, especially the outdoor serials
Can be “On”, “Off ” and “Automatic”. The cameras with IR Cut Filter [IR Cut Filter control]
have a feature that combines the excellent daytime color with the IR night vision.
During the day, an optical “IR Cut filter” removes all IR light. This makes the camera's
vision similar to a human eye which does not see IR light, and therefore all colors
appear vivid and natural to us. At night, the filter moves out of the optical path to
enable IR night vision. You can actually hear a muted click when this filter moves I
n or out. This happens both during power-up and when light levels change
between day & night.
Note: If you are using the cameras to look through a window, you should set the night
vision mode to turn off the IR LEDs and instead turn on the automatic moonlight mode.
Otherwise the IR LEDs would reflect off the window glass and the glare would make
everything almost invisible.
