Description

The AXIS On-screen controls API makes it possible for the user to receive information about various features of the camera. This information is available via a CGI, with the various methods described in the table below:

The On-screen Controls CGI methods

MethodUsage
languagesGet a list of supported languages and locales.
featuresGet descriptions of available features in one of the supported languages.
addFeaturesAdd information about a manually installed feature.
listAddedFeaturesGet a list of manually added features.
removeFeaturesRemove information about a manually installed feature.
getAllFeaturesGet a collection of feature descriptions in all available languages.
getSupportedVersionsGet a list of supported API versions.
enableFeatureShow the option to enable/disable a feature.
disableFeatureRemove the option to enable/disable a feature.

Model

The Api consists of a CGI which should be called using the HTTP/HTTPS Post method, and with JSON formatted data as input. The CGI includes a number of methods which gives the user the ability to:

  • Get a list of supported languages and locales.
  • Get information about available features in a given (supported) locale.
  • Add information about a manually installed feature.
  • List manually added features.
  • Remove information about a manually installed feature.
  • Get information about available features in all supported languages.
  • Get a list of supported API versions.

An API call includes the requested method along with any required input parameters.

Prerequisites

  • Property: Properties.PackageManager.PackageManager=yes
  • Property: Properties.AddOnFramework.Version=1.0 or higher
  • Firmware: 7.10 and later
  • Product category: Axis Cameras with application-support

Application Identification

The status method in the axis/addon.cgi lists axis-onscreencontrols as active.

Common examples

Languages

Use this example to check if feature descriptions can be displayed in a certain language.

1. Query for supported languages.

http://myserver/local/axis-onscreencontrols/onscreencontrols.cgi

JSON input parameters

{
"apiVersion": "1.0",
"context": "",
"method": "languages",
"params": {
}
}

2. Parse the JSON response.

Successful response

{
"apiVersion": "1.0",
"context": "",
"method": "languages",
"data": {
"languages": [
{
"language": "English",
"locale": "en-us"
},
{
"language": "Svenska",
"locale": "sv-se"
},
{
"language": "Deutsch",
"locale": "de-de"
}
]
}
}

API reference

See Languages for further instructions.

Features

Get a list of features that support the English language

Use this example to access and list the camera’s unique features, all of which supports the English language.
