Outstanding experience with Elwin Security! We originally worked with them on an intercom installation and later discovered they could help with another intercom issue that multiple technicians had been unable to solve for months. Elwin diagnosed and fixed the problem within hours. Jordan, Glen, Ben, Dino, Mike, and the entire Elwin team were professional, responsive, and kept us informed every step of the way. Their technicians worked so efficiently we barely realized they were on-site before the job was complete. We were so impressed with their service that we've onboarded Elwin as one of our preferred vendors and have already started recommending them to our clients for security and access control projects. Highly recommend!

Client feedback
What clients say about working with Elwin.
I read 5-star reviews all the time and am sometimes skeptical. Well let me tell you, I'm a multi-unit property manager, and this company came through for us in a massive way. Our electronic entry/intercom failed us on a weekend. As you can imagine, this is not only an inconvenience, but a huge security risk as well. There was no weekend service from our current provider, and it was like pulling teeth to get them out to even assess the problem. Then, once they figured it out, they projected like 10 days before they could get the parts and repair the system. We can't wait that long! With Elwin, as soon as we picked the new (upgraded) system we wanted, they told us how to prepare for the installation, and as soon as we had that done, they installed it the next morning. They were polite, efficient and communicative -- answering every question I had. Further, they have followed up to see that we are satisfied and have all the information we need to program and use our new system. Very impressive! I would highly recommend that you consider them for your security needs.
I originally brought in Elwin Security to install a ButterflyMX fob access system for our HOA clubhouse, and they absolutely knocked it out of the park. The installation was seamless, the system works flawlessly, and the entire process was handled with professionalism from start to finish. Jordan, Dino, and Mike were outstanding to work with — they were communicative, punctual, and clearly know their craft inside and out. They took the time to explain the system, answered all of our board's questions, and made sure everything was configured and tested before wrapping up. They did such a great job on the clubhouse project that I hired them again to install a smart lock at my home. Same excellent experience — clean work, no hassles, and everything functioning perfectly. If you need access control, security installations, or smart lock work done right, look no further than Elwin Security. These guys are the real deal.
"This HOA Board highly recommends Elwin. We initially hired them to handle our transition from DoorKing to ButterflyMX, and the entire process was seamless. Elwin provided an accurate quote and completed the project both on time and on budget. What truly set them apart was their exceptional post-installation support; they jumped in to resolve normal transition hiccups immediately, even assisting us on a Saturday. Because of their professionalism and reliability, we have already hired them for additional projects. Elwin is a vendor of excellent character, and they have earned our highest recommendation."
Jordan and his crew have been fantastic to work with. They’re quick to respond, easy to coordinate with, and always get the job done right. It’s clear they care about their work and take pride in helping their customers. I’ve used them at multiple properties and have always had a positive experience.
Great company and staff. Highly knowledgeable and helped us install Butterfly system for our property with 211 homes including Swimming pool, clubhouse, and the main gate. Jordan and his team are an absolute pleasure to work with. Highly recommend their services!
We’ve worked with Elwin Security across multiple office buildings for both access control and building security improvements. They helped us install and manage systems like Kisi, ButterflyMX, and Brivo, while also assessing the security of our buildings and installing maglocks and other hardware upgrades. They’re responsive, knowledgeable, and always great to work with. Highly recommend.
Elwin Security is great to work with. They are responsive, provide quality service, and offer reasonable prices. I highly recommend them!
Elwin Security just completed a ButterflyMX installation at our HOA ... flawless execution, and excellent customer service before, during, and after. I highly recommend them.
Dino and Mike from Elwin Security were fantastic to work with on our commercial building. They were professional, thorough, and clearly know their craft. From the initial assessment to the final install, communication was clear and they made sure everything was done right. The quality of their work gives us real peace of mind for the property. Highly recommend Elwin Security for any commercial security needs. Ask for Dino and Mike if you can!
Good efficient and responsive service
I am the president of the HOA of a 7 unit condo building in San Francisco. We recently replaced our old analog intercom entry system with ButterflyMX. Elwin Security is their integration and installation partner. The entire process, from the initial planning and coordination through today’s successful installation, was seamless and professional. The Elwin Security team was knowledgeable, responsive, and a pleasure to work with. Their expertise in security systems integration, along with their familiarity with ButterflyMX, made the entire process smooth and efficient. A member of their team’s previous experience with ButterflyMX was especially helpful in ensuring that everything was installed and working properly. We couldn’t be happier with the results. Elwin Security did an excellent job, and we highly recommend them to anyone looking for a professional, reliable security systems partner.
Elwin Security was the right choice for our new ButterflyMX security system installation. They had a 3-5 man team dispatched to our building for nearly a week getting us totally changed over from an old and outdated Syntex system that was installed a long time ago. The installation team was clean, polite and responsive to all of our needs and requests. There were a few change orders that were made on the spot and did not slow the best and pace of work or production. Their estimate of time and costs were accurate and no surprises came up during their work here. We have also added items after the work was completed and had software issues that Jordan at Elwin was ready and able to assist me. He was and is the perfect goto for us for this critical time of integration and startup. Always available and accessible. His knowledge of ButterflyMX on the software side as well as installation proved invaluable and helped enormously. In fact some of the videos I watched regarding ButterflyMX were produced and posted by Jordan. jordan was a wealth of knowledge and truly assisted and allowed for a smooth transition for us. I would hire Elwin in a heartbeat and their team is top notch. HIGHLY RECOMMENDED !!
Very efficient and smart people. They charged half of what a competitor asked for a complex wiring job. Elwin is great at finding affordable access control and security solutions.
Very professional, responsive, and knowledgeable! Great to work with.
Jordan and his team have been an incredible resource across my properties. They’ve handled every issue that’s come up with professionalism, patience, and a solutions-oriented approach. No matter the situation, they consistently find a way to resolve it efficiently and effectively. They’re also extremely responsive when it comes to scheduling, which makes coordinating projects seamless and stress-free. Their reliability and consistency set them apart, and because of that, they will always be my first choice for installing and servicing new camera equipment.
Why Elwin
We see the building before we choose the system.
Our site walk brings the hidden conditions into view—so your proposal is grounded in what the property actually needs.
One clear scope. One informed team. No guesswork on install day.
We identify weak points, incompatible hardware, blind spots, access conflicts, and wiring constraints before they become change orders.
Better decisions while changes are still easy to make.
Hardware we install
The right hardware. One connected system.
We select, install, and connect proven access control, video, intercom, door, and low-voltage equipment to fit how your property operates.

Compatibility judgment
Access, video, intercom, door hardware, and low-voltage wiring selected around what works together.
