Get pan/tilt position for Q3628 cameras

[BetterZhouXu]

I am using the the API http://192.168.86.1/axis-cgi/viewareasetup/center.cgi?mode=overview&pan=10&tilt=10 to change the camera's viewarea
Then I call another API to make it effective http://192.168.86.1/axis-cgi/viewareasetup/roll.cgi?move=auto&speed=25
I don't know if the camera moves to the right place. So I want to get camera's current pan/tilt position, I used this API:
http://192.168.86.1/axis-cgi/com/ptz.cgi?query=position
But it returned info "pan=0 tilt=0 zoom=1". Does anyone know how to get the pan/tilt information? And how to know if the camera moves to the right place?
BTW, lots of API document is missing from the VAPIX...

Answers to your questions will most often come from the community, from developers like yourself. You will, from time to time, find that Axis employees answers some of the questions, but this is not a guarantee. Think of the discussion forum as a complement to other support channels, not a replacement to any of them.

If your question remains unanswered for a period of time, please revisit it to see whether it can be improved by following the guidelines listed in Axis support guidelines.

@BetterZhouXu Why you change the view area and not the ptz position?

https://developer.axis.com/vapix/network-video/pantiltzoom-api/#ptz-control

Like http://myserver/axis-cgi/com/ptz.cgi?rpan=10&camera=3

The position is 0 because looks like you does not change the PTZ position instead you change the view area. (Digital PTZ)

And what are you missing ? :)

[BetterZhouXu]

Hi @Cacsjep , thanks for your reply.
I also tried to call http://myserver/axis-cgi/com/ptz.cgi?rpan=10&camera=3 then I called http://myserver/axis-cgi/com/ptz.cgi?query=position I got same result pan=0.00 tilt=0.00 zoom=1 Looks like the pan position is not changed.
I have two questions:

1. how can I change view area and validate it (view area is changed or not)?
2. how can I change pan position and validate it (pan position is changed or not)?

The missing part in VAPIX is: those calls for center.cgi and roll.cgi are not listed in VAPIX document, I was told by someone else. I don't know how to use center.cgi and roll.cgi before someone tole me, and I am not sure how to use it correctly.
BTW, opticssetup.cgi is also not in the document.

@BetterZhouXu Things that are not documented are unofficial and not supported by AXIS. You should use only official VAPIX commands and not unofficial ones obtained from Chrome Developer Tools or similar.

Why you are using camera 3 as argument, a PTZ camera would almoast have one sensor.
so testing it on a P5654-E PTZ /axis-cgi/com/ptz.cgi?rpan=10&camera=1 moving correctly the device.
and query with /axis-cgi/com/ptz.cgi?query=position also reflect these changes:

pan=22.73
tilt=-54.66
zoom=1
focus=1152
brightness=5000
autofocus=on
autoiris=on

I think you mix up, view areas and ptz in general, a view area is just a subview of the orignal. So when talking about PTZ moving whole camera the two cgi works correct:

move: /axis-cgi/com/ptz.cgi?rpan=10&camera=1
query: /axis-cgi/com/ptz.cgi?query=position

configure a view area is a diffrent kind of topic:

It's a typo, I just copied the command from you. But I am using camera=1 actually

@BetterZhouXu sorry my bad :)

[Cacsjep]

@BetterZhouXu is see now that Q3628 is not a PTZ camera. So therefore you can use PTZ commands. May describe your goal so then we can find the correct stuff for you :) when you just want to create an view area use the above Vapix commands from docs to create and list afterwards.

Hi @Cacsjep I want to implement a function: I detect cameras' pan/tilt/viewarea every 1 hour, compare current pan/tilt/viewarea with default values. I will reset those parameters to default values if deviation is found.

@Cacsjep I tried to change camera's view area through web interface. I found those two commands during the process:
http://192.168.86.1/axis-cgi/viewareasetup/roll.cgi?move=auto&speed=25
http://192.168.86.1/axis-cgi/viewareasetup/center.cgi?mode=overview&pan=10&tilt=10

Then I tried to use those commands to change view area for Q3628 camera, but nothing changed.

@BetterZhouXu
You should not use internal commands, use offical stuff, may your camera firmware is very old so please tell me which firmware version your camera has ?

Tested on my AXIS P3265-V Dome Camera with firmware 12.4.59

1. Using /axis-cgi/viewarea/info.cgi to get a list of all viewareas, and inspect the view area you are intersted
2. Using /axis-cgi/viewarea/configure.cgi to update/set a viewarea

1. 
2.
