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 detection area
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:
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.
Command: 80 4A 07 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 (%)
Up: 100%
Left: 100% |
| Right: 100% |
| Center | |
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.
