USING THE MENU SCREEN MOTION/SIZE
B SIZE setting
The SIZE setting will split the screen area in 64 (8 x 8) squares and
the detection is made by measuring movement and changes in each
of the squares. To set the size of the subjects to detect, it is
necessary to set the number of squares where detection should
happen simultaneously.
The MOTION SIZE setting lets you decide the size of subjects to
detect by setting the number of contiguous squares in both
directions (horizontal and vertical) where movement should be
sensed simultaneously before an alarm trigger is output.
Example: The illustrated four types of moving subjects (A, B, C, D) will be sensed and an alarm
trigger will be output or not, as shown in Fig.1, depending on the SIZE setting.
❍: An alarm is output
✕: No alarm is output
