Abstract

The present invention relates to an apparatus and a method for controlling a heating device (32) in a motorised camera directing arrangement (10) including a motor device (25, 27). The method comprising measuring a voltage over the motor device (25, 27), measuring a current conducted at least to the motor device (25, 27), measuring a temperature relating to the motorised camera directing arrangement (10), controlling power distributed to the heating device (32) based on the measured temperature and on the measured current, and feeding power to the heating device (32) independent of the measured temperature and the measured current in the event that the measuring of the voltage over the motor device indicates a voltage level higher than a predetermined threshold value.
