Monitor display (camera images)
Problem
Cause & Solution
Page
Even though there are
people, they cannot be
viewed at all or can only
be partially viewed.
R
You may not be able to correctly view people with the camera in the
following cases.
– When people are moving near the edge of the sensor range.
– When people move slowly or quickly across the front of the camera.
– When people move closely across the front of the camera (approx.
1 m).
-
Images are dirty or
unclear (out of focus).
R
There is dirt on the surface of the camera’s lens cover.
→ Wipe the lens cover with a soft, dry cloth.
-
Images are not displayed
with the correct
brightness.
R
The brightness in the area where the camera is installed is changing
rapidly.
→ Wait about 1 second. The brightness will be automatically
adjusted.
-
Images are blurry and
people’s faces or other
objects are hard to
distinguish.
R
When images of dark areas are viewed, due to the characteristics of
the image sensor of the camera, people’s faces can be hard to
distinguish. (This is not a malfunction.)
→ We recommend installing extra lights in the area around the
camera. (The camera’s LED lights cannot produce enough light to
illuminate the area in this situation.)
-
Objects in images are
blurred.
R
Images may blur when the subject moves. (This is a characteristic of
the image sensor of the camera and is not a malfunction.)
R
Images of objects can easily blur when images of dark areas are
viewed or if the object is dark.
→ We recommend installing extra lights in the area around the
camera. (The camera’s LED lights cannot produce enough light to
illuminate the area in this situation.)
-
White points or coloured
light points are displayed
in images.
R
White points or coloured light points may appear in images when
images of dark areas are viewed or if the object is dark. (This is a
characteristic of the image sensor of the camera and is not a
malfunction.)
→ We recommend installing extra lights in the area around the
camera. (The camera’s LED lights cannot produce enough light to
illuminate the area in this situation.)
-
Images have uneven
colour.
R
AC (alternating current) lights such as fluorescent lights may cause
uneven colouring or flickering.
→ Setting [Uneven colour prevention] to [On] may reduce the uneven
colour and flickering. (However, this may reduce the image quality
of images with dark areas.)
