STI’s story began over four decades ago in a home basement. We now operate from multiple buildings in Waterford, Michigan, have an office located in Worcestershire, England, and are recognized as a global leader in helping to prevent false fire alarms, theft and vandalism to important devices worldwide.

We care about the people we work with.

Family owned and operated, STI believes in treating their employees like family. Personal attention is paid to each team member and the company strives to make the work environment fun, collaborative and inspirational. We believe in what we do, and we believe in our colleagues to help us achieve our goals. STI offers a full benefits package and regularly participates in teambuilding events.
