Function Descriptions
[12] Stabilizer
By changing the image clipping position, corrects the
blurring images due to the shake at the camera.
Frequency that can be stabilized
This function corrects vibrations between 5Hz – 15Hz.
However, depending on the strength of the vibration
or the stabilizer level, some vibrations within this
frequency range may not be stabilized.
To minimize the blurring of the object when using
the stabilizer
In case there is blur of the object, especially the
object that is on the near side of the screen, set the
shutter speed to around 1/250. It could be effective to
minimize the blurring of the objects.
[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 16, total of 256 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:
・ 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.
detection area
・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 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.
In case of sending the request command to obtain the
pan-tilt distance of auto-pursuit while camera is in pan
or tilt movement, the camera will detect the movement
as a "motion" (false detection).
To avoid this false detection,process either 2 methods
below in the pan/tilt control microcomputer.
- Send the Pan/Tilt Degree command to the module
in every 75 msec.
- Abolish the result of the above request command
during pan/tilt movement and a result immediately
after stopping pan/tilt movement.
