Just switched our alarm monitoring service in order to have local oversight. Kyle was professional, informative and answered all of our questions pre install. The install was seamless and both Kyle and James were efficient and personable. Will be sure to recommend SSI to our friends.

I am a Superintendent of a 10-floor building and have been using SSI for many years. Their service has been beyond phenomenal. They have installed cabling throughout the entire building with great care and without damaging the building’s aesthetics.

When our intercom system went down from water damage, Kevin and his guys were there immediately to troubleshoot. We opted for a new system and they had us up and running right away! Great, reliable group of guys. Very knowledgeable, I highly recommend them.
