Autoiris / Autofocus

The driver's autoiris/autofocus functionality requires the unit's password to be set to 0000 (or 9999) in order to work. The 0000 (or 9999) password implies that the unit's advanced commands can be accessed without having to supply a password. After setting autoiris/autofocus, the driver locks the advanced commands .

Auxiliary Commands

The auxiliary cgi-request accepts the following strings:

on_n[_t]
Activates auxiliary function n. Corresponds to the remote control's On button.
off_n[_t]
Deactivates auxiliary function n. Corresponds to the remote control's Off button.
toggle_n
Toggles auxiliary function n.
latch_on_n
latch_off_n
Activates auxiliary function n until explicitly deactivated using latch_cancel.
latch_cancel
Deactivates auxiliary function activated using latch_on/off.
set_n
Sets preset position n. Corresponds to the remote control's Set button.
show_n
Show preset position n. Corresponds to the remote control's Show button.

where n is the auxiliary function (or argument) and t is an optional argument stating how long (in ms) the command should be repeated for. If the time argument is absent, the command is sent to the unit only once.

Examples:
on_40
Resets the unit to the factory default settings. (Remote control: On-40-Enter)
on_60/off_60
Turns the on-screen display on/off. (Remote control: On/Off-60-Enter)
on_90/off_90
Locks/unlocks advanced commands. (Remote control: On/Off-90-Enter)
set_110
Re-calibrates the unit and returns it to the factory default home position. (Remote control: Set-110-Enter)

Some auxiliary commands bring up an on-screen-display menu.This menu can be navigated using the up/down/left/right buttons (or a joystick). An iris command usually returns from the menu. For a list of available auxiliary (remote control) commands, please see the manual for the Philips unit.

Zoom

The Philips Autodome G3A has a 3.6 second delay at full optical zoom before activating the digital zoom (see the advanced parameter ZoomPerUnit below).

On the Philips Autodome G3A and when using a low zoom speed, the continuous zoom often stops too soon after a zoom direction change.

Video Source Configuration

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. 1-16384

Driver Specific Settings

Parameter Description Range
Flip pan If set to true, relative pan operations will be inverted true, false
Flip tilt If set to true, relative tilt operations will be inverted true, false

Mechanical limits

There are no mechanical limits for this driver.

Light Control

Parameter Description Range
Back light compensation Set to true to use the back light compensation. true, false

Extended Driver Specific Settings
Default values have been optimized for the Philips Autodome G3A.

Parameter Description Range
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. 1-7
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.
NOTE: The Philips Autodome G3A has a 3.6 second delay at full optical zoom before activating the digital zoom. This constant should thus not be set too low (i.e. ensure a "rzoom=9999" at full optical zoom activates the digital zoom).		 1-600
Focus time The calibration constant for focus changes (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. full focus far) takes you to the other. 1-30000
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) movements. 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
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). 0-100
