Function Descriptions

[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 ON/OFF Setting
Sets auto pursuit to ON/OFF.
Command: A0 34 00 0p CS FF
p: OFF: 0、ON: 1
Auto Pursuit Sensitivity Setting
Sets the sensitivity to brightness variation when
detecting motion.
Higher sensitivity increases motion detection through
less brightness variation.
Command: A0 34 01 0p CS FF
p: 1-F (High sensitivity – Low sensitivity)
Note:
・ W hen auto pursuit is set to ON, the ALARM
MOTION setting is forcibly set to OFF.
・ P ursues the largest moving subject when several
moving subjects are detected within one angle.
・ F or Day/Night models, when the IR cut filter is in
operation the moving subject is not pursued.
・ W hen the zoom lens, focus lens are in operation, the
moving subject is not pursued.。
・ W hen the PAN/TILT information is changed, the
moving subject is not pursued
・ W hen 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.
Command: 80 4A 07 CS FF
Response: C 0 4A 07 0p 0q 0r 0s 0t 0u
 CS FF
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 (%)
Left: 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.
