  • We had SEi in every house until we moved to our current home 5 years ago.  At that time, we went with a referral from a friend.  The other company's service was adequate, but we couldn't be happier to be back with SEi and we won't make that mistake again.

  • 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.
