  • We hired SEi to design and implement the security system for our law firm's new building. Everything went smoothly from the first presentation of SEi's capabilities to the contracting phase to installation and through final training. The system is easy to use, but as with any new system or building, we had lots of questions. Response times from the Remote Services department have been outstanding. SEi did what they said they were going to do, and for the fee they quoted. No surprises - and that's something we like.

  • SEi has been prompt, professional and just plain great to do business with. We wanted to secure our home and family and they answered all of our security questions. And they are local, great people.

  • Everything was seamless from scheduling to the install to completion. The techs were respectful of our house and took the time to make sure we knew how to use the system upgrades.
