Thermal Spotmeter

The thermal spotmeter can trigger events based on the measured temperature. The measurement area covers the four pixels at the center of the image.

Important Note

The temperature of objects in the image as determined by the thermal sensors is influenced mostly by the following factors:

This means that the sensor can deliver different temperature values depending on the distance to the object and the current scene. In order to define events that are based on temperature trigger values, you first need to determine the current temperature values measured in the scene. To do so, you can use the variables $(SEN.TSR.CELSIUS) and $(SEN.TSR.FAHRENHEIT) for the right sensor or $(SEN.TSL.CELSIUS) and $(SEN.TSL.FAHRENHEIT) for the left sensor. The determined values can then be used to set the trigger value defined below.

General Settings of the Thermal Spotmeter

Show Crosshairs

In order to exactly point the sensor to the object you want to measure, the camera can display crosshairs in the live image. The circle at the center of the crosshairs shows the four pixels that are used for measuring.

Temperature Unit

Show the temperatures either in degrees Centigrade (°C) or Fahrenheit (°F).

Trigger Values

Enter the temperature value that is used to trigger an event when it exceeds or when it drops below the value (depending on the setting of the Comparison parameter, see below).


Select between triggering the event when it exceeds or when it drops below the specified trigger value.

Action Type

Define how often the event is to be triggered:

Memorizzazione della configurazione

Fare clic sul pulsante Imposta per attivare le impostazioni e salvarle fino al prossimo riavvio della videocamera.

Fare clic sul pulsante Default per caricare i valori di default di questa finestra di dialogo (opzione non presente in tutte le finestre di dialogo).

Fare clic sul pulsante Ripristina per annullare le modifiche più recenti che non sono state memorizzate in modo permanente nella videocamera.

Fare clic sul pulsante Chiudi per chiudere la finestra di dialogo. Durante la chiusura della finestra di dialogo il sistema verifica eventuali modifiche nella configurazione. Se le rileva chiede di memorizzare in modo permanente l'intera configurazione.
