Wireless Security Alarm

Wireless security alarm system that uses wireless cellular technology to signal a 24 hour central monitoring station if a burglar breaks into your home or business. A burglar cannot defeat this cellular security system by cutting the phone lines outside the premise. No installation is required. Nationwide coverage anywhere in the USA where there is cellular service available through AT&T or their cellular roaming partners. Visit our website: www.Guardcom.net
