Guardian Solutions has the security industry's most advanced and largest product line of intelligent video surveillance systems. They convert outdoor cameras into an automated intrusion detection system eliminating the need for guards to continuously monitor camera displays. Guardian's products work where video motion detection fails by generating too many false alarm. Guardian's technology learns the natural outdoor environment such as trees swaying and clouds casting shadows. Abnormal activity is then discriminated from the natural environmental activity. The abnormal is tracked as a possible intruders. When its movement or location violates security rules, video and audio alarms are generated.Guardian's products are used by Fortune 500 companies, US military and transportation facilities.
