When I worked nights I also installed a light timer that would turn lightson and off at certain intervals. But let me stress that if you can afford it, and it makes you feel secure, ADT is a worldwide company that will deliver peace of mind to you and yours. On the good side the window stickers and the lawn sign are worth their weight in gold! The signs and stickers that advertise that your property is monitored and protected by ADT, are often stolen and sold. The advertisement is worth more than the monitoring fee. I diplay mine from the inside. I don't have the monitoring, but I feel secure knowing my dog is safe!
