When power to the control outlet drops, the Smart Strip cuts power instead. For example, when a printer plugged into a basic smart strip goes into standby mode, its power consumption drops. And since each remote can work on several frequencies, you can decide whether to control multiple Conserve strips with a single remote or with a different one for each strip. In a black-and-white TV, this signal can consume about 3.5 megahertz (MHz) of bandwidth, while in a color set the limit is about 3.0 MHz.



The composite TV signal described in the previous sections can be broadcast to your house on any available channel. By using the two-way audio system, police can communicate with anyone from suspects to hostages.
