Wireless communication system

A method for controlling a wireless communication device, comprising:

• each one of a plurality of wireless communication devices remain in an inactive state while a passive motion detection device, comprising each one of the wireless communication devices, does not detect motion;
• a first one of the plurality of the wireless communication devices transitioning to an active state, and enabling an active motion detection device, comprising the first wireless communication device, when motion is detected by the passive motion detection device;
• enabling an audio communication function, comprising the first wireless communication device, when motion is detected by the active motion detection;
• the audio communication function comprising the first wireless communication device remaining in the active state while an active motion detection device detects motion;
• and
• the first wireless communication device transitioning to the inactive state and disabling the audio communication function and the active motion detection function when the active motion detection device no longer detects motion.
