With 24/7 alarm system monitoring, if an intruder attempts to break in, a very loud alarm will be set off and the police will be notified that there is a break-in taking place, allowing them to arrive within minutes. This will deter the thief, and he will discontinue his mission and take off running. Unfortunately, with the crime rate on a steady incline, the addition of an alarm system to your home is a really good idea, as it can drastically lower the chances that your house is targeted by a criminal.
For a small additional fee, smoke alarms and carbon monoxide detectors can be added to your alarm system, which will also be monitored 24/7 to ensure your family is safe from fire or a possible toxic leak. Also, adding an alarm system to your house can also positively affect your insurance premiums, which will go down through various additional insurance discounts you can receive for going that extra mile to protect your home and belongings.
