Do we need a Wireless Alarm?

They have been having a rash of home break ins here in my city lately. It really makes me wonder if it's finally time for us to invest in a wireless alarm. I think the house would feel more secure. I have four cats, and I really don't want anything to happen to them. I love my babies. I really haven't checked to see what it costs yet, but does it really matter when it comes to my families safety? I think not. I'm going to call on Monday.
