No it's not. If you live in a detached house your phone line, power, water, cable, etc, is readily accessible from outdoors. I've never robbed a house, but it seems pretty prudent to cut those things with an axe before you enter. Maybe thieves aren't doing that because security systems are commonly battery backed? They would have to be cellular as well. I'm not sure, but your original concern does not seem far fetched.
