The Day/Night function improves the camera's sensitivity by automatically switching the camera to the color mode
in bright conditions and to the black-and-white mode in dark situations.
Using this function enables 24-hour surveillance with clear video images even during nighttime or in dark locations.
You may also fix the camera to the color or black-and-white video mode without using the Day/Night function.
Automatically switching camera between color and black-and-white video modes using Day/Night
function
Switching camera between color and black-and-white video modes when an external control signal is
received
Fixing camera to color or black-and-white video mode
This function is supported only by VDC-HD3300P/VDC-HD3300.
The configured settings will be applied to “CAM1” or “CAM2”, whichever you selected under [VIEW].
In AUTO mode, turning off the camera in the black-and-white mode and then turning it back on again
switches it to the color mode.
The focused position may differ between the color and black-and-white modes.
When using infrared lighting in the black-and-white mode, the camera may switch to the color mode
due to strong reflection from objects in the subject. In this case, adjust the infrared lighting to prevent
the switching of video to the color mode.
