Detection condition
Subject size: A moving subject needs to be equal to or larger than 1/48 of the screen at "STABI-
LIZER OFF".
Subject contrast: The contrast ratio between the background and moving subject needs to be
equal to or larger than 5 % (at maximum sensitivity).
Subject moving speed: The passing time for a subject to move from the end to the other end of
the screen needs to be equal to or larger than 0.8 seconds (at 5 % of contrast ratio). A sub-
ject moving faster than the description above is undetectable.
Note:
The larger the contrast ratio (difference between brightness and darkness) becomes, the
less the limitation on the size and moving speed of a subject becomes.
Demonstration mode
The brightness change in each of 48-split blocks is detected, and the mask is covered on the
block where the change in the average brightness exceeds the specified detection sensitivity
level.
The adjustment of the detection sensitivity level and the setting of the detection areas are
repeated to obtain an optimal state on the basis of the results in the demonstration mode.
Description about motion detector function (MODE2)
This function provides an alarm signal when a change in the state of a photographic subject
occurs by covering the camera with a cloth, a cap, or others, or by changing the camera direc-
tion largely.
Important:
• A change in the state of a photographic subject may not be detected in the following
cases:
• When only a part of the lens is hidden, or the cover is transparent,
• When the photographic subjects are similar between before and after changing the
camera direction.
• False detection may occur in the following cases:
• When a change in brightness is significant such as turning on and off a light,
• When the traffic volume including people and cars is high.
