When someone attempts a break-in, it is essential to have prompt detection and alert the proper authorities.

Aside from detecting intruders, some of the most convincing reasons to invest in a monitored security system are other changing conditions in your property. Fires, water problems, and dangerous carbon monoxide levels are some of the threats we can detect when you are not present— as well as who is coming and going through your front door when you are away. In a security event, time is of the essence. It is the job of our trained monitoring staff to observe these indicators reported by your home alarm system and resolve potentially hazardous situations.



  • When the alarm triggers on a monitored security system, our trained Central Station operator can promptly contact you and emergency services in real-time.
  • An alarm siren going off doesn’t mean people will react. They are so accustomed to hearing sirens from false alarms. They often are ignored. Central Station personnel are notified of every alarm alert and keep a history of your account.
  • If there is a fire in an unoccupied home, and monitoring is non-existent, you leave the chance of timely detection to the neighbors. In many cases, there are no noticeable signs of a problem outside the home.
  • With live monitoring services, individuals on your emergency contact list receive a notification.
  • Most insurance companies will offer you significant savings on your homeowner policy if you have a monitored alarm system.
