VAPIX PTZ Controller
====================

VAPIX is the Axis camera API:

http://www.axis.com/techsup/cam_servers/dev/cam_http_api_index.php

The communication with the camera is based around HTTP response and
requests. The returning value for success is

-  HTTP\_NO\_CONTENT (204): Command has been sent
-  HTTP\_OK (200): Command sent

and response in text format. The returning text format is structured as
[propertyName]=[propertyValue]

The username should have Administrator privileges to be able to manage
camera presets.

Inverted camera
---------------

If the camera is mounted inverted, set these 3 properties:

::

    cv.lecturesight.vapix.camera.inverted=true
    cv.lecturesight.vapix.camera.tilt.min=-9000
    cv.lecturesight.vapix.camera.tilt.max=2000
