]That's easy. Disguise your NID by relocating it or burrying it in a ]dry spot. Now setup a dummy NID with a very obvious phone line wire ]going to it. Wire that dummy phone line to a zone on your alarm.
As has been said often, in many places phone lines are above ground and run to telephone or hydro poles. Ie, a dummy is very very easy to see-- it does not run up the telephone pole. And the line is outside and possible to get at. The run down the house is hideable-- eg inside the walls (although the telco is going to be loath to do that-- the line is continuous from the pole to inside the house usually. And if an attacker really wants to they could use a tree trimmer with a long pole to just cut the line, even if it is 15 ft above ground.
]Burglar cuts what he thinks is a phone line and the alarm goes off. ]Cheaper than radio or cellphone backup.
Burglar follows line from telephone pole to house and knows which it the right line.
](An alternative is to wire the dummy phone line to 220V so the burglar ]gets dead if he cuts it. Just make sure it's not a lineman for the ]phone company.)
And you get charged with premeditatied murder.
