When making any purchase decision you are faced with numerous other mini choices that ultimately lead to your final decision. This is no different for a security system. Today I’m going to talk about some of the barriers that face us in regards to a security system. We are going to examine those barriers and ask ourselves if they are true barriers, or if they are just excuses.

One of the most common objections to purchasing a security system is the cost, as it is with almost anything that is perceived as expensive. Security Systems are becoming more and more affordable, and cost is becoming less of an issue. If you were given the choice between being burglarized or purchasing a security system the answer is fairly apparent.

This is one of the most common questions that I hear when I talk about security. I’d like to rephrase the question though, because need, is a strong word, and most of us don’t need a lot of things in life, but we still get them. I think the better question is why should I have security. The first part of the question refers to living in a low crime area, so I’m going to address that first.

What Our Clients Are Saying

  • EJ Fabian

    My house alarm was going off earlier in the week, thankfully it wasn't a burglar, but I was having a difficult time turning it off. Your dispatcher had one of your on call technicians call me to teach me how to reset the alarm and within minutes I was back online. Both of the Main Security employees I spoke with me gave me excellent customer service.

  • Ryan G. Poulin

    Having been a client of Main Security for 20 years, I can tell you that they have made my life easier. Their personalized systems are very easy to use, and their competitive rates are always a plus. I’ve stuck with them because they are always responsive and they have excellent service.

  • Brent A. Burger

    We use Main Security Surveillance for our security systems, temperature monitoring, and as our computer network manager. They are reliable! Nothing is more disconcerting than wondering if my protection is working or not. That is why we use them as our total solution to security for our physical stores as well as our data. As a first time buyer the team at Main Security made everything easy to understand.

  • Gary Levesque

    Main Security Surveillance is very professional and always there when you need them. Once, while on vacation, my low temperature monitor alerted their central station. If it wasn’t for Main Security, I would have come home to burst pipes, a flooded home and a huge headache. This is one of the many reasons I trust them to monitor my home and business. I also work long hours, and with a child at home, I feel better knowing there is extra protection there for her.
