some of the big box stores have DIY security systems. they require that you do most of the monitoring but have lights & sounds that go off if someone broke in, even cameras to catch pics of the intruders. most now will alert you through a cell phone. it may be a deterrent that could help.if you do get one with a camera make sure you have a sticker on one of the doors that states the house is video monitored since most states people need to be 'informed' of this when they are doing something illegal to you/your property.
have you checked to see if there are other home security monitoring company options in your area? Brinks i know used to advertise home security systems but i think they've changed their name recently.
