I have been using Post Alarm for years and referred them to several of my friends. One nice thing is this alarm company is locally located, not like others , which is located out of state. Their workers at their office are polite and helpful. They don't charge you if you had three or more false alarms, like some others do. And when an alarm goes on, they will call you right away, and let you know which area in house did intrigue the alarm, they will ask you to go and take a look, while they wait for you on the other side, just to make sure you are safe. And if you don't reponsed after they tried all your contact numbers, they will call the local police for you to check on your house, to make sure your safety. Very professional service.
