Flawless install. I would hire them again in a heartbeat!! Thanks for keeping us safe.

Dempsey is the best when it comes to Customer service, integrity and technology know-how. Eric and crew installed the original alarm in my home in 2013 and recently added a system for an ADU. They are very thorough, knowledgeable and fair. With Dempsey Alarms, you get an honest professional who follows up, takes care of all your concerns and makes sure everything works. I've recommended Dempsey Alarms to numerous friends and family and will continue to do so. read more

We hired Dempsey Alarm and have used them for the last six years. Excellent customer service... Great company.

Dempsey Alarm did a great job today in trouble shooting my problem and getting me back up and running. Kenneth was professional, friendly and knew what he was doing, and he didn't try to upsell something I didn't need like some other companies do. I highly recommend this company! This is the third time I have used them and I'm very satisfied with their overall service. read more

We had a new security alarm system installed today by Blake and Gage. Both were polite and efficient, plus considerate of our home. Blake spent extra time to patiently show us how to use the electronic monitoring aspects of the system. Good customer service is rare nowadays, so we appreciate the professionalism they displayed. Feeling secure at home is important to us and we feel Dempsey Alarms is providing us with peace of mind. read more

I write very few yelp reviews, but felt that based on the service and experience I had with Dempsey Alarms, it would be unjust not to write this review. I contacted Eric and he came out for a quote on upgrading my current non-working system. He was extremely polite and knowable. All the current (old) keypads were not working and several door and window contacts had to be replaced. Two techs came out (Kenneth and Gage) and installed new keypads and repaired all the non-working contacts. I cant say enough about their work and attitude. Very informative and professional. Kenneth went out of his way to make a few modification to our system that we requested. Not easy, but he didn't give up until he was able to make the system work exactly as we wanted. I highly recommend them, you will not be disappointed. Greg M read more

I would recommend Dempsey Alarms for their superb reliability. There is someone in office to take your call, who is empathetic and knowledgeable. Eric, the owner, is so incredibly professional and kind. Great team overall. Exactly all the qualities and qualifications needed in a security company you can trust. read more

Wonderful communication! Top quality installation. Sold me what I wanted not what they thought I "should" have. After looking at other options, I am VERY glad I went with Dempsey. read more

We recently moved to Oceanside and we had Dempsey Alarms install our security system. The 2 technicians (Kenneth and Q) who came to install were pleasant and friendly and they cleaned up the place before they left. Even after my system was installed and I needed more info about the system, Eric was very responsive to my questions. So pleased we chose Dempsey Alarms where their customer service is top notch. read more

Super knowledgeable, friendly, and responsive. By far the best deal and speed of service when I was shopping around. Eric knows his stuff and was very friendly and easy to deal with. They monitoring service has always been responsive with alarm trips. No issues, and a very affordable service Great value read more

Dempsey gave us an estimate for a four-camera Ring security system that was half the price of ADT and works great. They also upgraded our wifi by adding a mesh router that is extremely fast and reliable. read more

Eric is great! We had him install a Ring system around our property back in 2018 and just had him back to replace two of the cameras that had started to show wear and tear. read more

We had another company before and they were more expensive, and less responsive. Dempsey gets to know their customers and are locally owned. They take care of their customers and the prices are great read more

Eric and Kim are the Best!!! Eric helped me trouble shoot my alarm system via the phone and got it back working again without coming to my house. I would not hesitate to call Eric or Kim for any of your security alarm needs! Professionalism at its Best!!! I owe you Eric. Thank you and have a Prosperous 2024. God bless and keep up the Great Work! Eric's company has the best customer service. read more

Great company! We used them to put in our system during Covid in 2020. I had some issues with it this week, and the owner came out the next day and fixed it within 15 minutes. Also showed me how I could easily fix it myself next time. So nice and responsive. Super impressed. Highly recommend. read more

Really happy with the service Dempsey Alarms provided. We got 4-5 quotes for the type of home security system we wanted, and the best offer came from Dempsey. The price is reasonable/competitive and the service is excellent. Eric was communicative and answered all our questions. The install was smooth, Daniel was great at getting everything done efficiently and professionally. They guided us through the operation -- the alarm.com system is simple and easy to use. What we really appreciated was the professionalism displayed by both Eric and Daniel. Much better than other, bigger, more popular companies that approached us. We found Dempsey on Yelp and we'd recommend them to anyone for their home security needs. read more

Spectacular service from Eric and Kenneth! After having a bad experience with another company, I called Dempsey Alarms and they provided the most outstanding service! Eric called me back within only a few minutes, scheduled a technician to come out, and installed a fantastic system that I am very happy with. Kenneth, the Installer was extremely professional and hard-working. Can't say enough good things about this company. read more

Great company. Personalized Service. Much better than the large company that i had previously. I would highly recommend Dempsey Alarm for cameras, security system and monitoring read more

car key duplication excellence service and quality product with a reasonable price!! read more

I had Dempsey Alarms install the security cameras on my house and have been very pleased with the quality of the cameras and the quality of their work. At various times, three different technicians came to work at my home, and all three of them were very professional, courteous and efficient. Daniel, the last tech to come by, went out of his way to help me with my dog, even though I'm sure that wasn't in his job description. I would recommend this company without reservation. read more

I can't sing their praises enough. They installed an alarm system and exterior/interior home surveillance. The entire crew was diligent, thorough, competent, punctual, professional, considerate, patient, and sincere. read more

Great experience here at Dempsey. The owner is amazing and he will make sure you are satisfied with the service! Will definitely use them again read more

After a year of having a Dempsey Alarm system in place, I wanted to finally provide an update. After reviewing 4 alarm companies, and having a full interviews with 3, I chose Dempsey Alarm. Over the past year, I've had an alarm go off while I was away and police respond (extremely quickly i might add), I have had many multiple oops situation with kids and hitting the wrong button & only a positive experience with the dispatchers, had a billing error that was immediately fixed with a single communication, and a battery go out in one sensor that was repaired for free within a couple days. I've never had a alarm system but required one with our new home insurance - between the ring cameras and the alarm system they installed, I've never felt concerned about the safety of my family once. read more

Laura's service is simply amazing!! Thank you so much for your help!! Angela of Servpro La Jolla read more

I was more than satisfied with the work done by Eric Dempsey, professional, courteous and high quality work. He gives all the options to provide the security system we would need and installed it in a timely manner. The best part of Eric and his team including his secretary Kim is the response time when there is an issue. They call back immediately and take special care to address the issue in a timely manner. I had an issue with one of the sensor in a window not working properly, he guided me to purchase the sensor and helped me in programming the alarm system over the phone, all for no charge. So glad to have Eric and team install my alarm system! read more

Eric and his crew at Dempsey Alarms are fantastic. I needed my alarm system upgraded and taken over. Eric provided the most competitive quote out of other 'alarm.com' vendors. He was honest, punctual, his suggestions saved me money; furthermore he was very patient and explained pros and cons of various panels and answered all my technical questions (being an engineer it was very important for me). Eric and his crew never tried to upsell me on anything, or aggressively pressure me to sign the contract with them, and were very respectful of my home. Since installation I called Dempsey Alarms with a couple small requests. Eric is always there and does his utmost best to ensure his customers are always taken care of. The system has worked without any issues and everything that was promised was delivered. Lastly I'd like to add that Dempsey Alarms NEVER requested for me to write this review. There are other security companies in San Diego which I cannot name here who have a suspiciously high amount of 5 star reviews. I recommend thoroughly reading through them to understand why that's the case. It's against Yelp's policy for businesses to solicit reviews, apparently that policy is not very well enforced for certain companies. And if you do decide to get a security system (or upgrade the old one) meet with a few alarm companies before committing. read more

I called Dempsey Alarms after I called out another company, they wanted to set cameras their way and told me I didn't need a monitor. When I called Eric out he understood exactly what I wanted and said no problem. Set a time and date which they showed up right on time (wearing mask) Daniel Ortiz & Matt Lostritto and went right to work. When they finished they cleaned up spotless. I called them back the same evening because I am a dinosaur and I could not get my well needed Netflex, Daniel showed up fixed the TV no problem. I told Daniel I needed a control for my monitor to lazy to get up lol. Three days later they showed up with my remote and a bigger monitor. I can't say enough good things about this company Highly recommend. read more

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. I highly recommend this company for their honest, professional and timely work ethic. read more

Eric Dempsey and team have been absolutely fabulous. They are very responsive, I am able to communicate via text message with the owner versus waiting on hold for hours with the big alarm companies. They did a seamless install and were quick to respond when we had a small hiccup in the setup of the system. Seriously, you would have to be a glutton for punishment to go with the big national companies. I am so incredibly pleased with Dempsey Alarms and would recommend them to anyone. read more

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! read more

I have a very old alarm system that was here when we moved in 17 years ago. We called ADT and they proposed replacing it for a few thousand dollars. I then spoke to Eric at Dempsey who sent out his tech, Matt. Matt replaced our 4 non-functioning sensors in an hour. Total charge $195 ($120 of that for parts). The one problem that Matt couldn't fix was that the system has always been difficult to program when windows needed to be bypassed. Because it was so old it did not respond to the usual commands to simplify this. The next day Eric called, researched the problem, and solved it over the phone without an additional charge. Dempsey is great.......Very reasonable, responsive, and went out of their way to help. read more

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. Highly Recommend read more

I'm experiencing a learning curve with respect to the alarm system, but feel much more secure in my home. The Dempsey representative who installed my system did an excellent job installing my system and training me on it. read more

This business installed our alarm system years ago after a flood in our home. Since then, the system has worked perfectly. When it came time to change the battery system, they responded in a very timely manner. Q showed up on time and was extremely professional and efficient. The repair took no time at all and the fee was extremely reasonable. I cannot recommend this business highly enough. read more

Thank you for being honest and knowledgeable. I have an older un-monitored system and Matt came out and replaced both of my motion sensors in under an hour. Great service. read more

I requested quotes to replace my dead 25 year old system. Dempsey crushed the others, both on install and recurring monitoring pricing. Their installer was great, worked hard, got it all in and working. He showed us how to use it. We are very happy. read more
