Computer assisted for Speed and Accuracy

24 hour UL monitoringCommercial and Residential Alarms:  Our state-of-the-art computer and telecommunications equipment puts precise dispatch information at our security operators' fingertips. For residential alarms, we establish computerized profiles that include medical histories, sensor locations, and names and phone numbers of trusted friends or relatives you want notified in the event of an emergency. For commercial alarms, all pertinent information about the enterprise, zones, entrances, conditions, etc., is entered into your profile, including a call list of personnel to be notified for when emergencies are encountered. Central Station monitoring is the lifeline between the protected premise and the authorities. The authorities can be the police, fire or emergency services departments in your community.

24 Hour Monitoring? A must...

24 hour monitoring - essentialMonitoring service is critical to the success of your home or business security system, and for many different reasons. A siren and flashing lights may not scare away intruders. If your neighbors aren't home (or don't care) to respond to your alarm, the intruder(s) can burglarize your home or business very easily without monitoring. Likewise, if you are home and unable to call 911, you may not be able to receive emergency assistance in a potentially dangerous situation. And if you are not home or the business is closed up for the night, and a fire starts (assuming that you have fire detection equipment and monitoring) early detection by monitoring can mean the difference between "some" loss and a home or business that burns to the ground. Passersby, for a business or residence with an alarm sounding, often do just that:  pass by - they may feel that it is none of their business, or that it might be a false alarm. Monitoring, 24 hours a day, is your critical link to prevent losses of many different kinds.
