Basic Functions
Motion Detection Function
This function instructs the camera to detect movement
within the monitoring area and then send an alarm
signal automatically.
The Detect signal goes out through the serial command
(VISCA) communication line.
Features
• You can set a frame for the detection range of 12
(horizontally)
×
8 (vertically) blocks.
• You can set up to four frames.
• When the motion is detected in the set frame, the
Alarm Replay VISCA command is sent.
• The threshold level for detection can be set (common
to four frames).
• The interval of alarm detection can be set up to 256
seconds in units of one second.
• You can set on/off for each frame.
• The frame number is also sent with Alarm Replay to
report in which frame the motion has been detected.
Frames
Setting frames
You can set the frame by assigning the starting point
and terminating point vertically and horizontally. You
can set up to four frames.
When motion is detected within the rage
where frames overlap
The alarms are sent for both frames.
14hex (20(10))
14hex (20(10))
At this position, the
alarm for frame 3 is
sent.
Within this overlapped
range, alarms are sent for
both frame 3 and frame 4.

Sets the center position “x” of the Mask on screen.
Sets the center position “y” of the Mask on screen.
rr
Sets the half value “w” of the Mask Width.
ss
Sets the half value “h” of the Mask Height.
See “pp: x, qq: y, rr: w, ss: h” in “Parameters” on page 19.

Commands:
Mask does not interlock with pan/tilt.
The limitations of parameters are as follows.
(hexadecimal representation)
x: ±50h
w: ±50h
y: ±3ch
h: ±3ch
Note
When the Set Mask command and the Non Interlock Mask
command are set to the same mask, the command set later
becomes effective.
Grid
Use the grid displayed on the screen to set mask
positions (see the figure below).
By executing the Center Line On command, only the x
and y axes of the center are displayed. Grids lines
disappear.
