  • After dealing with two other local companies, we contacted SEi and couldn't be happier.  They are far advanced with their technology and worked nonstop (it seemed) to get us up and operating.  5 stars all around for the complete staff.

  • To anyone looking to put a security system in your home.  SEi is bar far the best system and we recommend them to anyone looking for a security system.  Yes, we looked at all the ones out there and got pricing from them all.  SEi is not the cheapest system out there, but that should not be the driving force when protecting your family and property.  I have been in sales for over 20 years and can tell you, that SEi takes quality, customer satisfaction and service to a top level.  The sales consultant that came out to our house called ahead, was on time and very thorough and his attention to our needs and what we were looking for in a security system was nice to see.  This to me is what makes or breaks the first impression a customer has.  When we received our proposal, it was very professional and had everything on it that we talked about and the exact price we would pay for install and our monthly cost.  When it came to install, the installer was very professional and took all the time needed to make sure we were happy with the install of each component and knew how to run and that we understood the system.  SEi's customer service was very nice to work with also and we even got to talk to a live person, YEAH!!! If you are looking for a great local company that pays attention to quality, service and attention to detail, give SEi a look.  I promise you will not be disappointed.
