Working with Elwin was easy and stress free! From getting a quote all the way to installation, Jordan and his team communicated well and executed the project with no issues. Could ask for nothing more than great communication and customer service.

Client feedback
What clients say about working with Elwin.
Elwin Security is awesome! Any job you have, they can get it done. Super timely responses, polite staff, and beautiful work. Anytime I have a project that requires some low-voltage work, wiring, etc. Elwin are the first people I call.
I had an outstanding experience with Elwin Security from start to finish. Jordan, our sales representative, was incredibly professional, knowledgeable, and responsive throughout the entire process. He took the time to answer all of our questions, made sure we understood every step, and provided exceptional customer service. The installation team was equally impressive. They arrived on time, worked efficiently to replace our old outdated system with our Swiftlane system (which the residents love), and completed the installation quickly without sacrificing quality. Their professionalism, attention to detail, and respect for our property truly stood out. The response time from everyone involved was excellent, and the entire process—from the initial consultation to the final installation—was smooth, organized, and hassle-free. It's refreshing to work with a company that values customer satisfaction and delivers exactly what they promise. I highly recommend Elwin Security to anyone looking for reliable security solutions backed by exceptional customer service, fast response times, and outstanding workmanship. Thank you, Jordan and the entire installation team, especially Mike for such a great experience! We appreciate you at Terraces
I can’t recommend Elwin Security enough! We were having a major access control issue with our ButterflyMX system at my apartment complex. Before finding Elwin, I had three different security vendors come out. Each one charged us for service, and none of them could identify or fix the problem. After speaking directly with our ButterflyMX representative, they highly recommended Elwin Security, and now I understand why. I spoke with Jordan, who had a technician scheduled to come out the very same week. Mike, the technician, diagnosed and fixed the issue in just a couple of hours. It was honestly impressive to watch him resolve something that three other companies couldn’t figure out. What really stood out was Mike’s communication and professionalism. As I continued making my rounds around the property, he kept me updated every step of the way. He took the time to explain exactly what the issue was, showed me what he was doing to fix it, and made sure I understood the solution before he left. Mike was quick, knowledgeable, professional, and reliable. The entire experience with Elwin Security was outstanding from start to finish. 10/10: I highly recommend Elwin Security for any access control or security system needs. They definitely earned a lifelong customer.
Our HOA recently partnered with Elwin Security to replace our aging, 20-year-old access control system with ButterflyMX, and I can't say enough good things about the experience. This was a large and complex project involving nearly 40 access points across our community, including pedestrian gates, building entrances, garage doors, elevators, amenity spaces, and common area doors. Migrating from a legacy system that's been in place for two decades is never straightforward, but Elwin Security made what could have been a very stressful process feel manageable. The team replaced outdated controllers and power supplies, installed new hardware including latch retraction kits where needed, integrated the new ButterflyMX platform, configured the system, tested every access point, and worked through countless compatibility issues that naturally arise when modernizing an older property. They stayed with the project until every door and gate was functioning exactly as intended. What truly sets Elwin Security apart is their commitment to their clients. Jordan and his team were incredibly responsive throughout the entire project. They answered calls at all hours, made themselves available whenever issues came up, and even came out on weekends to make sure our residents experienced as little disruption as possible. At no point did we feel like we were facing problems alone—they treated every issue with urgency and took ownership until it was resolved. As President of our HOA, I've worked with many contractors over the years, and Elwin Security is one of the best vendors we've partnered with. Their communication, technical expertise, professionalism, and dedication to customer service are second to none. They didn't just install a new system—they became a trusted partner throughout the entire migration. If you're an HOA, apartment community, commercial property, or business considering an access control upgrade, I highly recommend Elwin Security. They stand behind their work, genuinely care about their customers, and deliver exactly what they promise.
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!
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.
