We reached out to Elwin Security after our previous security camera vendor retired. From the start, they were willing to work with our existing equipment rather than push for unnecessary replacements, which is something we truly appreciate and have found to be a rarity.
Their team coordinated directly with our staff for an onsite visit, quickly diagnosed the issue, and successfully resolved the problem without any downtime or the need for additional parts.
As a nonprofit organization, we value working with businesses that understand the importance of cost-effective solutions, reliable service, and building lasting relationships. Elwin Security demonstrated all of these qualities, and we believe they will be a valuable business partner moving forward.
We appreciate their professionalism, honesty, and excellent service and would gladly recommend them!

Christina, thank you for the thoughtful review and recommendation. We're glad we could step in after your previous vendor retired and get your existing cameras working again, with no downtime and no unnecessary replacements. Working with what you already have is how we think it should be done, especially for nonprofits where every dollar matters. We appreciate the trust your team placed in us and look forward to being a long-term partner. If anything comes up, we're a call away.
As a general contractor specializing in hotel renovations across the country, we occasionally encounter warranty issues that require prompt attention. After contacting several other local door repair companies with no success, Elwin Security answered my call and was able to mobilize a technician the very same day.
Not only did they resolve the issue, but they also provided excellent documentation before the close of business, allowing me to promptly update the hotel's ownership team.
Their responsiveness, professionalism, and follow-through were outstanding. We sincerely appreciate their efforts and will certainly be using Elwin Security again for future projects throughout Northern California.
Highly recommended!

We appreciate your trust in Elwin Security and look forward to working with you on future projects in Northern California. Please reach out if there’s anything else we can help with!
Jordan at Elwin Security has been extremely helpful. We worked with him on the installation of a ButterflyMX intercom at one of the buildings we manage in Oakland, and he was very professional throughout the entire installation process.
Even after the installation was completed, Jordan and his team have continued to be very responsive and helpful. Every question or issue we’ve had has been addressed promptly, and they have always been available when we needed assistance.
Great service and great support. Highly recommended!

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.

Josh, thank you for the thoughtful review. We're glad the process from quote to installation was easy and stress free. Jordan and the team take pride in clear communication and clean execution, so it means a lot to hear that came through. We appreciate your trust in Elwin Security.
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.
Response from the owner · 2 months ago
Thank you, Makeila. We appreciate the kind words and the trust you put in us for the low-voltage and wiring work. Timely, polite, and done right is exactly the standard we aim for. Glad to be your first 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

Jada, thank you for the thoughtful review and for trusting Elwin Security with the Swiftlane upgrade at Terraces. We’re glad Jordan made the process clear and responsive, and that Mike and the installation team delivered a smooth, efficient installation with the care your property deserved. It’s especially great to hear that the residents are enjoying the new system. We truly appreciate your recommendation and look forward to continuing to support 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.

Cheyleen, thank you for sharing your experience and for giving Elwin Security the opportunity to help after several unsuccessful service visits. We’re glad Jordan scheduled your service quickly and that Mike was able to diagnose and resolve the ButterflyMX access control issue. His communication, technical expertise, and commitment to keeping you informed reflect the service we strive to provide. We truly appreciate your trust and recommendation, and we look forward to supporting your property for years to come.
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.

Rickie - thank you for this. We know migrating a 20-year legacy system across 40 access points is never as straightforward as the spec sheet suggests. Jordan and the team were glad to work through the latch retractions, controller swaps, and weekend calls to keep your residents moving without friction.
You noted something we think about often: our job isn't finished when the hardware is installed. Standing behind the work - especially on legacy modernizations - is what we aim for.
We appreciate your partnership and the trust the HOA placed in us. If anything comes up, we're a call away.
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!
