1. A camera for use with a power supply, the camera comprising:

  • a voltage detecting circuit adapted to detect a voltage level at the power supply and to generate a voltage level signal;

    an image capture system for performing a set of power-consuming image capture operations; and

    a controller that prevents the image capture system from performing the set of image capture operations when the voltage level signal indicates there is power available in the power supply which is less than sufficient to perform all of the operations in the set of image capture operations, whereby the camera is rendered inactive before the power supply has practically run out of power.
