Yud came to our house, helping us identify the best positioning for the cameras and quickly generating a quote that beat the other companies. The system is very easy to use as it is all controlled by the Alarm.com app. I highly recommend Smart Shield to anyone looking into home security systems, they really take care of you.

Somehow they were able to restore all of them and added hard-wired cameras, glass break listeners, smoke detectors, remote front door lock, and tied into my existing garage door openers - all controlled by the easy-to-use Alarm.com software. Mateus did a great job configuring the alerts and teaching me how to use the mobile app. Yud brings an incredible amount of knowledge from his experience and military background into designing your system. I thought the price was very fair considering the piece of mind they have given me and my family.

This was a comprehensive build, a Dolby 9.1 system, and involved a great deal of craftsmanship, fitting speakers flush in the ceiling, routing wires, etc. It looks and runs great. I particularly liked the RTI device he set up, since its a master controller and is programmed to operate the many components in a coordinated way. My wife just presses one button and we're streaming, or we're playing 4k disks for movies. Spectacular. I'm particularly pleased that Gregg is always there when you need him. The rare time a component fails or when programming needs to be modified, Gregg is always prompt and capable, brining me a solution every time.

They ran into a concrete wall (literally) with one of the locations we wanted and they worked around it fine. I appreciate when contractors don't tell you how impossible something is going to be and just find a way to take care of it. Dane estimated it would maybe take 3 hours and it only took 2 (and they only charged me for 2 hours). It was only a little more expensive than hiring someone through Amazon for $99/hr (we were burned before so was happy to find HTSD). I typically like to get 3 quotes...one guy we asked for a quote took a week to get back to us (after the job was already done) and the other quote we got was $600 (roughly the value of one of the TVs).

Service Requested: Camera installation, upgrades, and system troubleshooting…read moreQuality: 3/5- their cameras do not offer the audible noise that they advertise Value of service: 3/5 - could be improved by offering multiple ranges of camera options instead of the most expensive one knowing customers will ask for other options to compare. We've used Halcyon Mobile Security Solutions for almost 5 years even through an ownership change for various upgrades, repairs, and new camera installations. Overall, the quality of their work has been solid once completed, and their technicians are knowledgeable and professional on-site. We did run into an issue with a camera that was sold to us by a previous rep (who is no longer with the company). The camera's speaker never worked as promised, and it took quite a bit of back and forth to troubleshoot. While the team eventually helped address the concern, communication delays made it harder to resolve quickly. Another recent project, getting a quote and installation for an additional camera -- took about two weeks from start to finish. While that's not terrible, shortening that turnaround could really improve the customer experience and help boost their sales, since responsiveness is key in this kind of service. Despite some bumps, we continue to use Halcyon because they do solid work once the ball gets rolling. With a few improvements to follow-up times and communication, they could easily earn that fifth star.
