It will keep the dummies out. All the new systems are wireless and use Lithium 123 batteries. Have ADT give you a discount on a case otherwise they will set you back $15 every 4-6 months per sensor.

Being wireless the pro's use jammers but unless your nest is housing some high price goodies your will be ok. 17 minutes is a LONG LONG time you need a dog to supplement your point and click defence.

Glass break detectors are great it's a specific frequency that glass makes when broken. It's what saved my office during the recent burglary attempt. Were on cell phone backup but that can be overkill for your average home.

Don't overlook physical security. You want to be a hard target <img src="/forums/images/graemlins/cheers.gif" alt="" />
