[13] Auto Pursuit Function
Detects movement on the screen and calculates the
level of movement.
Subject pursued: Walking person
Area:1x Zoom, object = a person at 8m distance
Speed: 4km/hour - 6km/hour
Motion detection: Uses the motion detection function
Detection area: 16 x 12, total of 192 blocks
Detection conditions: Continuous movement

Auto Pursuit Sensitivity Setting
Sets the sensitivity to brightness variation when
detecting motion.
Higher sensitivity increases motion detection through
less brightness variation.

p: 1-F (High sensitivity – Low sensitivity)
Note:
・
When auto pursuit is set to ON, the ALARM
MOTION setting is forcibly set to OFF.
・
Pursues the largest moving subject when several
moving subjects are detected within one angle.
・
For Day/Night models, when the IR cut filter is in
operation the moving subject is not pursued.
・
When the zoom lens, focus lens are in operation, the
moving subject is not pursued.
。
・
When the PAN/TILT information is changed, the
moving subject is not pursued
・
When LONG SHUTTER, SENSE UP is set, auto
pursuit cannot be set to ON.
Moving Distance Query Command
Returns the distance to the distance derived from the
center of gravity of the moving subject. This value
represents the distance. Calculate the PAN/TILT
distance adequately using this value.

Parameter description:
p: Movement direction (Lateral) (1: Right, 2: Left)
q: Movement direction (Vertical) (1: Up
、
2: Down)
rs: Lateral movement distance (%)
tu: Vertical movement distance (%)
Up: 100%
Center
Right: 100%
Left: 100%
Down: 100%
Example: when p = 0x01, q = 0x01, rs = 0x64, tu =
0x64, the PAN/TILT moves right: 100%,
up: 100%. Control the PAN/TILT moving
distance so that the subject in the top right
corner is in the Center.
The minimum transmission interval of movement
distance query command is 150msec.
