Move speed |
The current maximum pan and tilt speed. |
1-100 |
Pan move time per degree |
Panning 1 degree takes this amount of time (unit = 1s/10000). Changing "Move speed" requires this parameter to be recalibrated. Calibriation is done by requesting a 360 deg pan (i.e. "rpan=360") at current "Move speed" and then adjusting this parameter until the request pans exactly 360 degrees. If pan speed(deg/sec) is known, this is calculated by 10000/(pan speed). |
1-15000 |
Tilt move time per degree |
Tilting 1 degree takes this amount of time (unit = 1s/10000). Changing "Move speed" requires this parameter to be recalibrated. Calibriation is done by requesting a 90 deg tilt (i.e."rtilt=90") at current "Move speed" and then adjusting this parameter until the request pans exactly 90 degrees. If tilt speed(deg/sec) is known, this is calculated by 10000/(tilt speed). |
1-15000 |
Trunc tilt speed |
As it must be possible for the tilt function to be correctly calibrated for all available device types, the "speed curve" that describes the full range of tilt speeds will, for some devices, have no effect at the higher end of the scale. This means that the maximum speed (i.e. "Move speed"=100%) needs to be "remapped" to the highest value on the speed curve that still results in increased movement. This value might be e.g. 75% for one particular device, but 90% for another device.
To set this parameter, first set it to 100%. Then progressively raise the maximum tilt speed until there is no further detectable increase in the speed. This value (e.g. 80%) should then be used for the Trunc tilt speed.
Changing this parameter also requires a recalibration of the "Tilt move time per degree."

Zoom time |
The 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 (i.e. "rzoom=9999") at one extreme (i.g. zoom wide) takes you to the other. |
1-30000 |
Focus time |
The 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 (i.e. "rfocus=9999") at one extreme (e.g. focus near) takes you to the other. |
1-30000 |
Current field angle |
The calibration constant for click-in-picture (center). Higher values give greater 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 |
The 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 |
The 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 |
Goto preset delay |
Time (in seconds) it takes for the image to stabilize it self, after the camera has performed the longest "goto preset action". Used for disabling/enabling image analysis (e.g. motion detection). |
