Autofocus / Autoiris
Autofocus is automatic set on when moving pan/tilt directions and when zooming.

Basic Parameters

Parameter Description Range
Device ID This is the address of the connected device. This value corresponds to the value of the address switches in the connected device. 1-256

Advanced Parameters

Parameter Description Range
Move speed Current maximum pan and tilt speed 1-100
Pan move time per degree Panning 1 degree takes this long time (unit is 1second/10000). Changing "Move speed" requires a re-calibration of this parameter. Calibriation is done by requesting a 360 deg pan (e.g. "rpan=360") at current "Move speed" and adjusting this parameter until the request pans exactly 360 degrees. If pan speed(deg/sec) is known, calculate by 10000/(pan speed). 1-15000
Tilt move time per degree Tilting 1 degree takes this long time (unit is 1second/10000). Changing "Move speed" requires a re-calibration of this parameter. Calibriation is done by requesting a 90 deg tilt (e.g. "rtilt=90") at current "Move speed" and adjusting this parameter until the request pans exactly 90 degrees. If tilt speed(deg/sec) is known, calculate by 10000/(tilt speed). 1-15000
Trunc tilt speed The tilt speed curve is truncated. This is the maximum speed in the linear area. This is the percentage of the real maximum tilt speed that "Move speed"=100% will be mapped to. To set this parameter you must measure the tilt speed curve while having this parameter set at 100. Changing this parameter requires a recalibration of the "Tilt move time per degree". 1-100
Zoom time Calibration constant for zoom (time in ms for maximum zoom change). Higher values give greater zoom changes. Calibrate by confirming that a maximum zoom request (e.g. "rzoom=9999") at one extreme (e.g. zoom wide) takes you to the other. 1-30000
Focus time Calibration constant for focus (time in ms for maximum focus change). Higher values give greater focus changes. Calibrate by confirming that a maximum focus request (e.g. "rfocus=9999") at one extreme (e.g. focus near) takes you to the other. 1-30000
Current field angle Calibration constant for click-in-picture (center.) Higher values give larger movements. Calibrate at minimum zoom (i.e. zoom wide) and at the most commonly used speed, by making sure that clicking on an object brings the object to the center of the image. 1-900
Pan bar range Range (in degrees) to use with "panbar" requests. Clicking at the very end of a bar will pan half this value in the corresponding direction. 1-720
Tilt bar range Range (in degrees) to use with "tiltbar" requests. Clicking at the very end of a bar will tilt half this value in the corresponding direction. 1-720
