Anyone have any "creative" alarms for an apartment or know where to get some type of cheap alarm system? I feel pretty secure where I live but I am a young single female living alone and sometimes at night I get a little scared. Not often though! lol Ive heard of putting bells by your door. I have a dog that will bark but will not necessarily protect me. But thats another issue. I tried searching online but some of the systems are $250 something I can not afford right now. Anything you know of?
