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: 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.

Command: 80 4A 07 CS FF

Response: C0 4A 07 0p 0q 0r 0s 0t 0u

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.
