Our Customers Say

Rated 5 Stars!“Was connected to Brian to assist in an older client’s need. Instead of upselling and trying to go after the money, he recognized the age of my client, the need and provided options. Brian also offered to assist in the future if we had the need. Because of this encounter with him, I feel comfortable in making future business referrals in the future.”

ADT Security vs. Alarm Engineering – Security Comparison

You know all the benefits of a monitored home security system, including (but not limited to) 24/7 monitoring, wireless technology (no phone line needed), real-time notifications, smart home technology, and homeowner insurance savings. Now you’ve started the process of researching the best home security alarm company for you.

Most locals know Alarm Engineering, but if you haven’t heard about us yet here’s a a little about our team and what we stand for. We are locally (and family) owned and have been around since 1985.

Big Enough…and Small Enough

You may wonder whether local is the best choice when it comes to security. Rest assured, with Alarm Engineering you get the best of both worlds. We are the largest locally owned and operated alarm company on the Shore – so we are large enough to serve your needs 24/7, but still small enough to care about you. Check out our Google Reviews to hear it directly from our customers.

Perhaps you’re considering ADT Security, too. You see lots of ADT ads – they are the national name everyone knows. Without any experience with either company, how can you make the choice that’s best for your family, business, church or community?

We believe in education, so you can make the decision that’s best for you. We don’t believe in high pressure nonsense. When our customers switched to us from ADT Security, we asked why they made the decision to switch and have compiled the most frequent answers.

Do You Already Have Hardware Installed?

Even if you already are with ADT Security or anther company, we can probably monitor your currently installed system. We’ll send a technician out at no charge to test and reprogram your system for free!


Here’s a quick checklist of the important differences between Alarm Engineering and ADT 

Security FAQ

Alarm Engineering

ADT Security

Does this company offer 24/7 professional monitoring and a system I can control and monitor with my smartphone?



Is this company licensed, bonded and insured?


There are both ADT Corporate and ADT Authorized Dealers. Check with the entity you’re getting the quote from to be sure.

Does this company have a same day service guarantee anywhere on Delmarva?


Many customers who came to us from ADT Security had a hard time getting service (after the sale) here on Delmarva.

Does this company start with a ‘teaser’ monitoring rate, then raise prices frequently once you sign up?

Never. In our 30+ year history, Alarm Engineering has raised our monitoring nominal amount, for a TOTAL of $2.50.

Many customers who leave ADT Security called us because their rate just keeps going up and up – just about every year in fact. If you’ve been with ADT for more than a couple of years, we can likely save you money.
