Autofocus
|
Autofocus is implemented using a one-push-autofocus command, which is executed after any pan, tilt or zoom change.
A focus request disables autofocus.
|
| |
|
Autoiris and preset positions.
|
An iris request disables autoiris.
The state of the autoiris is not saved in a preset position. The driver will, after sending a goto preset command, send an autoiris command (manual or auto depending on the current state of autoiris) to the PTZ-unit.
|
| |
|
Digital zoom
|
| In order to enter the digital zoom range, a zoom request must be sent when at full optical zoom.
|
| |
|
Initialization
|
| If the PTZ unit is not physically connected during camera mapping (including driver installation) or is reset during operation, the unit may need to be reinitialized. This is most easily accomplished by remapping the camera (uncheck and re-check the corresponding "Use with source" checkbox under "Video Source Configuration").
|
| |
|
Preset positions and digital zoom
|
| Digital zoom is temporarily disabled when saving a preset position, as it is not possible to save a preset position in the digital zoom range.

| Parameter |
Description |
Range |
| Move speed |
The current maximum pan and tilt speed. |
1-100 |
| Move pan per degree |
The calibration constant for panning. Higher values give greater movements. Calibrate at the most commonly used speed, by adjusting the value until a 360 degree pan request (i.e. "rpan=360") pans 360 degrees exactly. |
1-3000 |
| Move tilt per degree |
The calibration constant for tilting. Higher values give greater movements. Calibrate at the most commonly used speed, by adjusting the value until a 90 degree tilt request (i.e. "rpan=90") tilts 90 degrees exactly. |
1-3000 |
| Zoom speed |
The current zoom speed. NOTE: The set value is mapped to 4 discrete speeds. |
1-100 |
| Zoom per unit |
The calibration constant for zooming. Higher values give greater zoom changes. Calibrate at the most commonly used zoom speed, by confirming that a maximum zoom request performs a maximum zoom. |
1-600 |
| Focus speed |
The current focus speed. NOTE: The set value is mapped to 4 discrete speeds. |
1-100 |
| Focus per unit |
The calibration constant for focus. Higher values give greater focus changes. Calibrate at the most commonly used focus speed, by confirming that a maximum focus request performs a maximum focus change. |
1-600 |
| Iris time |
The calibration constant for iris changes (time in ms for maximum iris change). Higher values give greater iris changes. Calibrate by confirming that a maximum iris request (i.e. "riris=9999") at one extreme (e.g. full iris close) 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. |
1-1800 |
| 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 |
| Digital zoom max |
The maximum digital zoom. |
1x (off), 2x, 4x, 6x, 8x, 10x |
| 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). |
