Thermometry

The VAPIX® Thermometry API provides the information that makes it possible to configure the temperature monitoring functions on a temperature calibrated thermal camera:

Isothermal palettes: Pixels colored differently depending on their temperature for an overview of the temperatures across the scene. You can choose between a number of palettes that can be either isothermal or non-isothermal. The chosen palette is stored in the parameter Image.I0.Appearance.Palette, which is used by the majority of thermal cameras, including those without thermometric capabilities. However, only thermometric cameras have isothermal palettes as an option, further detailed in getIsothermLevels and setIsothermLevels. Three temperature levels must be provided if an isothermal palette is chosen. These temperatures will be tied to three distinct colors in the palette. Temperatures between and outside of these levels will be linearly mapped to the colors of the palette. An image of the palette and the three levels can also be included in the video stream as an overlay.
Temperature detection areas: Defined numbers of polygon-shaped areas in which the temperature can be monitored. You are able to set a number of conditions that must be met before the alarm will trigger. For example, you are able to set a temperature limit that will trigger the alarm whenever the temperature goes above or below it. An alternative to the fixed threshold is setting a limit on how fast the temperature is allowed to increase or decrease. This means that you need to set a delay time (in seconds) before the alarm will trigger and if it will trigger on the highest, lowest or at an average temperature in the area. It is possible to include the areas as overlays in the video. The areas can also be tied to a preset on a mounted pan/tilt-device.
Spot temperature measurement: A single spot in the image chosen to measure the temperature. There can only be one spot temperature, which will then be included in the video stream as an overlay.

addArea

This method should be used when you want to add a new temperature detection area. The area is a polygon given as a set of coordinates in consecutive order where no edges may cross each other. Additionally, a number of conditions must be provided for when an alarm should be triggered. The maximum number of areas per preset is given by the method getConfigurationCapabilities.

This means that the upper right corner has the coordinates [1, 1], while the lower left corner has the coordinates [-1, -1].

Temperature information event

This event is uniquely assigned to an area. An update event is sent to each existing area every 30 seconds.

General error codes

The following table consist of errors that may occur for any method. Errors specific to a method are listed under their separate API description. The error codes exist in the following ranges.

1100–1199: Generic error codes common for many APIs and reserved for server errors such as “Maximum number of configurations reached”. The actual cause can be seen in the server log and can sometimes be solved by restarting the device.
1200–1999: API-specific server errors that may collide between different APIs.
2100–2199: Generic error codes common to many APIs and reserved for client errors such as “Invalid parameter”. These errors should be possible to solve by changing the input data to the API.
2200–2999: API-specific client errors that may collide between different APIs.

Note

The 4–digit error codes are returned in the JSON body when the service is executed, which means that the client must be prepared to handle transport-level errors codes with non-JSON responses. Specifically, HTTP error 401/403 will be emitted if either authentication or authorization fails.

JSON code	HTTP code	Description
`1100`	`500`	Internal error.⁽¹⁾
`2100`	`400`	API version not supported.
`2101`	`400`	Invalid JSON.
`2102`	`400`	Method not supported.
`2103`	`400`	Required parameter missing.
`2104`	`400`	Invalid parameter value specified.
`2105`	`403`	Authorization failed.
`2106`	`401`	Authentication failed.
`2107`	`4XX, 5XX`	Transport-level error.

Out-of-memory errors will also be reported as 1100 Internal error.
