Step 1
Move the cursor to "BW MODE" and select the black-and-white control from the following:
AUTO: Automatically toggles between color and black-and-white images in accordance with the screen brightness (illuminance).
The simple black-and-white mode is selected for dark images, and the color mode is selected for bright images. The IR filter does
not change over.
A color image is changed to black-and-white image when the ambient brightness (illuminance) of the camera is approx. 0.1 lx or
less.
OFF(default): Displays color images.
Note:
• If a subject is always moving or the screen is occupied with a uniform color, brightness determination may be not performed suc-
cessfully because the brightness is merely determined by information from the CCD image sensor.
• To obtain color images, a sufficient level of illuminance (approx. 30 lx or more) is required.
• The switching illuminance level varies with subjects, light sources, and lenses.
• The switching illuminance level varies in accordance with AGC setting. (☞ Page 11)
• The switching illuminances described above are reference values. The switching illuminance shall be decided based on the actual
installation environment.
9. VMD setting [VMD]
The VMD function can detect a motion of an object and interference in camera operation. When the VMD function detects a motion
of an object and interference in camera operation, an alarm signal can be provided.
Refer to the following for important information about the settings regarding motion detection function and interference detection
function:
Important
• The detection function does not work properly in the following cases: In such a case, adjust the detection area or detection sensi-
tivity.
• The brightness (illuminance) level between the background and moving subject is similar, or the change in illuminance is sig-
nificant.
• The lens is dirty or has a water droplet on the surface.
• The luminance of an image is low, e.g. image in the night.
• A subject is moving straight toward the camera or vice versa.
• A subject moves too fast or too slow.
• A subject is too small or too big.
• Moving objects are too many.
• A subject is in a reflective environment such as subject behind a widow or subject in reflection of road surface.
• The camera is swaying.
• A subject is receiving external light such as sunlight and car headlight.
• A fluorescent light is flickering.
• The interference detection may not work in the following cases:
• Only a part of the lens is hidden, or the cover is transparent.
• Subjects are similar between before and after changing the camera direction.
• The detection function may not work properly for approx. 1 minute after turning on the power, after completing settings in the
SETUP menu, and after changing the camera view angle.
