The electronic watchdog. Never sleeps. Always on duty.Who's guarding your front door when you are out and about, or after you went to bed? What about a well-trained guard dog with a hightened sense of hearing who keeps an ear out and starts barking as soon as anyone approaches your frontdoor? That's what the CC-2200 watchdog does.
