    Really great experience (from start to finish) working with this family-owned company! When I say…read morefamily-owned, I mean that Mary, her husband, and their son will come to your house to install your new system. That level of family-owned. First and foremost, Mary has fantastic communication. When I initially sent my quote request, she responded quickly and thoroughly. Throughout the process, I had multiple questions (new to this), and she took the time to carefully reply to each question via email. This level of responsiveness is super important to me especially when it's a field I'm not knowledgeable in. There are a lot of moving parts when alarming a house and it was important that I understood exactly what we were getting. Her team did a great job installing our new security system. Everyone was very nice and professional. They took the time to explain everything and asked our input (regarding placement, etc.) whenever necessary. Mary carefully went through everything in the app to get me set up and familiar with the interface. They were also very respectful of our home -- offering to either remove shoes or put on their own shoe covers (we're a shoe-free household with small children so this is important to us). I also really appreciated how customizable everything was. There are so many different options that are offered with the security system (including a lot of automation like locking doors and controlling lights, etc. that we weren't actually interested in). If you're a newbie like me, I'll break down the basic security options. It helps to have some understanding of what's available before you get started. I was a little overwhelmed but Mary was helpful in answering my questions. Anyway, you've got a keypad that controls your alarm system (arm/disarm). You can do that via app (even if not home) or key fob. Then you've got your various sensors. Obviously, the door open sensors are a must. They'll trigger the alarm if someone opens the door (when armed) and is unable to enter the proper disarm code. Then you've got the option of installing window open sensors. There are also glass break sensors (generally, one per small room or two for large rooms) that will notify you if a glass break is detected (or if house is armed, set off the alarm). Finally, you've got motion sensors (these are automatically turned off when you arm your system in stay mode versus away). Assuming you'll wire the doors, you need to decide if you want glass breaks and if so, whether they will cover full home or just most vulnerable areas; if you want window sensors and if so, on all or some windows (might depend on your window type and vulnerability to window being manually opened and whether glass breaks might be sufficient); and whether you want motion sensors and which areas you want them to cover. I'd recommend doing some preliminary research/planning on how these tools might fit your home and what coverage is necessary versus overkill. It depends on your layout, etc. Next, you've got cameras. They offer WiFi-based cameras (operated through alarm.com) and standard wired cameras. Video doorbells too. We replaced our Ring with their doorbell cam to centralize our camera controls. You can have everything controlled through the alarm.com app for convenience. The app is great -- very user-friendly. Anyway, there are a lot of other options available as well that I didn't even delve into. Thought I'd share the basics to get you started. Don't hesitate to use this company! They offer free in-person consultations and fantastic service -- professional, friendly, knowledgeable, and responsive. Oh and their rates seem reasonable and competitive. Very pleased with this experience as well as our new alarm system! BIG THANK YOU!

    We contacted Security Consultant Pros about purchasing cameras for our property as well as several…read moreother companies. We chose Security Consultant Pros because we felt really comfortable dealing with a smaller family owned company. They were extremely knowledgeable, professional and a very quick install. They walked us through how to operate and use the system and made sure we were comfortable with everything before they finished. We contacted them later about an issue we had with the system and they immediately helped us over the phone on what we needed to do to correct the problem. All in all, it was a very pleasant experience and we know that they are only a phone call away for any help that we may need. Thank you Security Consultant Pros for a job well done.

    We had a great experience with Securimax and are very happy we chose them. After a few incidents…read morenear our home, we decided it was time to invest in a full security system with cameras. We spoke with several companies, both big national providers and smaller local ones, and ultimately went with Securimax. What stood out was their local presence and the hands-on approach, especially from Jack, the CEO. The installation itself was fairly involved and took most of the day, but everything was handled smoothly and professionally. Since then, their service has continued to impress. They're very responsive whenever we have questions and have been flexible in helping us adjust or expand the system as our needs evolve. Overall, it's been a really positive experience.

    Absolutely the worst company I've ever dealt with!…read more I hired this security company thinking I was protecting my home, but instead I got stress, wasted money, and zero accountability. The installer showed up late, seemed completely unprepared, and didn't even know how the system was supposed to work. Sensors were crooked and one camera works only sometimes. When I asked about it, I was told "that's how I was told to do it" and "most people think it's ok". The system went offline multiple times, including once while we were out of town. What's the point of paying for the services if it doesn't work when you need it most? Customer service is a joke. Calls go unanswered and when someone finally responds, they act like you are the problem. Every issue was blamed on my internet, my phone, or "user error," even though the system wasn't working rights from day one. How is it my fault when the app says that a camera is offline? What am I supposed to do but contact them. I pay them monthly for the service, so if something says it is not working then I think it's reasonable to say I can call them. What is not reasonable is for there to be no customer service when the system is malfunctioning. To make matters worse, I was locked into a contract and threatened with cancellation fees instead of offered real support or a fix. If you care about your safety, your money, or your sanity, stay far away from this company. I regret ever signing up. I thought I was doing good by going with a small company, but I should have called ADT, Vivint, or someone bigger.

I waited a…read morewhile to write this review, because I wanted to makes sure the customer service was just as great if I ever had an issue. I found Central Security on Yelp. Patrick answered when I called for service. It was down to Central Security and another home security company. Patrick explained everything to me and answered all of my questions. I was very appreciative of this because this was my first time owning a home security alarm system. I really love that since this would be my first time, there's no contact. I love that they believe in earning your business instead of being nice upfront and then not having to work to keep your business, because you're trapped in a contract. I signed up with Central Security and paid for my equipment upfront and my cameras. I just pay monthly for the active monitoring. One time after I was approached by another company a few momths after I been with Central Security, I called Patrick and let him know and he let me know he value my business and gave me a fair renegotiation on my monthly fee. The next month I bought another camera and has then install it. I'm also happy to report that the alarm does work I had a false alarm when I was away in away on a windy night and the wind push a an unlocked door open. The police ended showing up and the security center did call. Unfortunately I was sleeping at the time, but it was reassuring to know that the system really does work! I highly recommend Central Security. I've had excellent service, when they came to install the system they were punctual professional and fairly quick. This is the best deal in town with the fairest prices!

I like doing business with straightforward companies and people, recommended!

I now have rock solid WiFi both inside and outside my house ~600Mbps for an extended distance and constant speeds over Ethernet even faster than that. I highly recommend Eric to bring an old home up to modern technological standards.
