Wireless connectivity

Though wireless technologies (WiFi, Bluetooth) have been around for a while, companies continue to expand the use of wireless beyond computer  and headset communications. I've just seen a WiFi connected stereo which allows remote control by other devices such as iPhone or Android devices. New home control systems including lighting, alarm, and video monitoring are also now available, with more coming.

 Increased connectivity can  increase convenience, efficiency, and energy savings.  But security of the system is important to prevent compromising the control or information provided by the system.
