Not all home alarm companies are the same; there are some important questions to ask. It is important to find out who is doing your monitoring and where the central monitoring station is located. Many companies use third party sub-contracted home monitoring facilities that also monitor thousands of accounts for other security companies around the country. This may lead to poor customer service due to their limited knowledge of your home security system, emergencies that may be occurring in your area, and a breakdown in communication to the company servicing your system if your system should have a problem.
