SightLine Applications Command and Control

on.

Bit 4 High noise compensation

0 = off (default)

1 = on – improves tracking in very high noise

situations

Bits 5..7 Reserved = 0

6 Size of object of interest, in pixels. (Used for clustering in motion

assist and motion detection systems.) 0 = no change.

7 Maximum number of frames to keep looking for a non-found

object before stopping a track. (Default is 45 frames or 1.5

seconds.) Controls how long a track can be off screen or

obscured (eg. behind a tree) before the track will give up. 0 = no

change

Tracking Modes

Stationary Mode Used to track non-moving object (e.g. door, window, building, etc.).

Vehicle Mode

Used to track moving objects. Works best with relatively constant velocity

objects such as a car.

Scene Mode

Uses frame-to-frame registration to determine position of target. May work

better than Stationary Mode for low-contrast non moving targets.

Set Registration Parameters (0x0E)

Set parameters used by registration module.

Byte offset Description

2 Packet length = 10

3 Packet type = 0x0E

4 Maximum translation in pixels, LSB – default of 0 is equivalent

to 120 for a 480 high image (¼ of the image height)

5 Maximum translation in pixels, MSB

6 Maximum rotation range in degrees per frame: 0..10 (values

larger than 10 clipped to 10). 5 is default.

7 Maximum zoom range in percent zoom per frame: 0..10. 0 is

default.

8 Left image edge pixel band to ignore. 0..255. Used for overlays

or foreground objects that appear near the edge of the image. 0 is

default. At least ¼ of the smaller dimension of the image must be

remaining. For NTSC, remaining non-ignored image must be at
