If you really want to go deep into the AXIS cameras and know more information about the camera and its settings you can use AXIS VAPIX.
The prerequisite for public URL camera is any active Survilla cloud licence (Remote Access, Recordings, Timelapse)
A camera connected to the cloud receives a unique URL that allows remote access to the camera. The URL always consists of the camera's serial number and the first- and second-order domains device-connect.net.
https://SerialNumber.device-connect.net/
Such access is particularly suitable for programmatic control of the camera via the VAPIX interface.
VAPIX is an application interface that allows you to control the camera and change its parameters.
VAPIX provides functionality for requesting images, controlling Pan Tilt Zoom, controlling input/output ports, retrieving and controlling internal settings, managing events, recording and retrieving video to/from the SD card, and much more.
With remote access, you can also control the API of installed ACAP applications.
To authorize access to the camera and its VAPIX API, an API token with the Configuration permission (DEVICE_ACCESS_TOKEN) must be generated. The exact procedure for generating the TOKEN can be found in this article.
Example of a request to the camera API
From the URL and DEVICE_ACCESS_TOKEN you can make a request for the VAPIX interface of the camera:
https://serialnumber.device-connect.net/axis-cgi/param.cgi?action=update&ImageSource.I0.Sensor.Brightness=89&root.ImageSource.I0.Sensor.ColorLevel=91&DEVICE_ACCESS_TOKEN=NvA7fxxxxxtYVQ
where:
serialnumber is the serial number of the camera
/axis-cgi/param.cgi is the standard URL on the VAPIX interface
?action=update&ImageSource.I0.Sensor.Brightness=89&root.ImageSource.I0.Sensor.ColorLevel=91 is a VAPIX request. In this case, we change the brightness and saturation of the image
&DEVICE_ACCESS_TOKEN=NvA7fxxxxxtYVQ is a one-time access token listed as the last parameter of the query
