“we save money every month by setting thermostats to turn on or off based on when we are actually at home, star review

“Our Team here at Bayshore has utilized Security Instrument for securing our warehouses, temperature and humidity controlled Fine Art Storage and many other storage services for over 25 years! SI (as we call them) has proven to be a true partner and then some! SI has continually invested in the needed technology and the PEOPLE – the TEAM at SI is responsive and on top of things – when you get the call at 2 am about a motion sensor going off and you’re 2/3 asleep it is nice to have a professional person on the other line with accurate data.”
