Both an Elk M1: http://www.elkproducts.com/product-catalog/m1-gold-cross-pla... and a HAI Omni:http://www.homeauto.com/Products/HAISystems/OmniPro2/omnipro... can do this via email and can call your cell phone and speak the alarm to you and are UL listed fire/burglar system as well as fully programmable automation controllers.

They cost significantly more (about as much as a decent PC) but I would not trust my property or life to anything less honestly. My Omni has been running without reboot for years and does security/fire/hvac/irrigation/lighting/garage door control and has an iPhone app for control.
