Yup we're just looking into something for our bus, we got broken into a bout 2 months ago. They pryed one of the driver windows out, climbed in unbolted the 2 flatscreens, took the dvd, vcr, dvds, and cds they wanted, and 3 pillowcases for you know what!! Left the cd player, CB and speakers??? I think we want to go with a motion detector with a siren inside and out, and if they have the balls to steal from it when its a howling, then have at it!!
