Testimonials

Great service, installation, and pricing. So glad we called Dempsey rather than a big alarm company, as it felt like small business service and care with big business options and even an app to use for all our security needs. Highly recommend calling Dempsey Alarms when considering new service or changing providers.

Very professional company. The technician arrived on time for the install. The security system was installed in a timely manner and the technician instructed the staff on operating both the wall unit and the application for the alarm system. I would definitely recommend them for your business.

Another review that has been a long time coming - and this company definitely deserves high praise!

I have been a customer of Dempsey Alarms for over 3 years now, and as long as I live in San Diego, they will continue to have my business. I initially had Eric come out to evaluate our home and determine the best security setup for our needs; the system that was installed has been exactly what I was looking for - convenient, user-friendly (both the app and in-home panel), low-visibility, and most importantly, it provided that extra security for my family and home!

Every interaction I have had with the company - from Eric, to his technicians, and even the alarm response call center personnel - have all reaffirmed to me that this company prioritizes customer service above and beyond any other security company I have worked with!

If you are looking for a security company in San Diego, and you don't give Dempsey Alarms a call, you are doing yourself a disservice. None of the bigger, nation-wide companies can compete with what Eric and his company offer - a personalized experience, and customer service second-to-none.

Thank you for all the help - and the comfort of knowing my family and home are secure!

This company updated the 20-year old security system in our house when we replaced our windows. The fees were lower than some others we were quoted and the work they did for us was great. The owner of the company responds to us if we have questions or concerns. They arrived exactly as scheduled, worked neatly, and were respectful our our needs. We love that we can now monitor, arm, or disarm our system over the internet. When we reported having occasional problems connecting over the web, Dustin came out and replaced the cellular unit and it has performed flawlessly since. We got a feeling of personal pride and integrity from all the staff. We are glad we switched!

Thank you to Dempsey Alarms. I have an alarm system that was installed by All Secure that needed the batteries to be replaced.

After 3 calls in 3 days to All Secure and no call backs, I found Dempsey Alarms on Yelp and not only did I get someone that answered the phone but she had Eric call me back immediately to set up an appointment. The came out on the scheduled day and were able to replace all batteries in the system and on the sensors in no time at all.

I really appreciate that, even though they didn't originally install my system, they still treated me like one of their own customers. I would definitely do business with them.

THANK YOU!

You can never have too many 5 star reviews and we are adding another for Dempsey Alarms! Eric, the owner, returned our call on the first inquiry and took his time to explain the options avaiable to us. We had many questions as this is the first alam system we have ever had installed. Eric set up an appointment convenient for us within a week of our first call. Dustin was the technician and he arrived on time and immediately helped establish the best placement for door sensors, window sensors, motion sensors and glass break detectors. Dustin was extremely knowledgeable in all phases of the alarm system and guided us to the best choices for us. He was personable, courteous, honest, competent and professional. We are completely satisfied with our new home security system, the reasonable cost, and with the service and peace of mind provided by Dempsey Alarms.

Eric and Matt just completed our install. We needed to update our 9 year old ADT system to add cameras, phone controlled apps, etc. Eric designed the best alternative for us to both maximize coverage and stay within our planned budget. Install was clean and professional. These guys are great! Will be recommending them to friends and family...

Excellent!

Punctual, professional, courteous and knowledgeable. Our tech, Matt, did a super job upgrading our home alarm system.

He also did a great job explaining all the features, and making a few helpful changes in the system. The system is high tech, at a fair price.

I'm certainly very happy with Dempsey Alarm, and would recommend them highly.....

The prior Yelp reviews are right, Dempsey is a 5-Star business.

Laura's service is simply amazing!! Thank you so much for your help!!

I contacted Eric when our 8 year old ADT wireless alarm was having issues with the sensors and fault codes. He sent out Dustin promptly. Dustin arrived 10 minutes early and was very professional and cordial. He examined our problems and gave us a few options from minor repair to full system upgrade. We chose the minor repair and he told us we had a few window sensors that were placed upside down. He could've easily told us they were bad and sold us brand new sensors. He was honest and he fixed all our problems without any new parts. Our ADT system is just like new and working flawlessly.
