Wireless Security Alarm

I am also looking for an alarm system for my business

I am interested in installing a wireless home security alarm as they are easier to install than wired. Are they any good? Which are the best makes? Any negatives to be aware of?

This is a system that’s much cheaper in price than some do it yourself sytems. Looks like a lot of them have sold on Ebay. Does anyone know if the system actually works? How well with dogs running around the house?
