Great customer service. So far so good. Is a home security business with great customer service. Their real test will come in the coming months when I need support and after using the monitoring service.

Awesomeness! From initial presentation to the after sales service, I have been very impressed with the fabulous service and attention from the team. They did an awesome job of making me feel secure in my new home. The pricing was the most competitive as well. I am so excited by having a smart house tailored to my needs at a reasonable cost. It also is great to support a leader in the field but also a local MD business.

These guys are a breath of fresh air I talked to many, too many companies when we got our security system companies several years ago. These guys were the best hands down. Super friendly, super knowledgeable (they can actually make your home safe vs just giving you a key pad a motion and a door sensor) and they have been great over the years we have been using them. I now have them as my provider for our company office and I have referred them out to friends and family. I own a business, and It's tough to find a company in the service industry that actually does what they say they will. Larry and Jeremy at 1st Security USA not only do what they say, they go the extra mile to make sure your happy and informed about how to use your security system. That's why I came back to them when I needed another system, and why I will remain a customer for life.

Great products, great warranty, great company. Jeremy with 1st Security USA was our sales contact and he made switching from our old security system to a new and better one a breeze! We can't recommend their level of customer service enough. Great products, great warranty, great company.

Have worked with Jeremy and Larry at … Have worked with Jeremy and Larry at 1st Security for a few months now and they're great. They're far more responsive than any other alarm company I've worked with and they're focused on meeting your needs, versus endlessly trying to get you to buy more services and sensors that you might not need. In the house I just bought some other alarm company had installed a window open/close sensor on a window that doesn't open - probably fooling the prior senior citizen owners to pay more for more equipment they didn't need. I rest assured that 1st Security would never do something so foolish and greedy. They're good, honest people, and this is something that's unfortunately hard to find in the alarm business. I recommend them.
