STI (Safety Technology International) is the anti-vandal-protection and weatherproof-enclosure specialist whose Stopper polycarbonate covers, weather-rated enclosures, and tamper-protection cages prevent the field-damage and weather-exposure failure modes that take fire-alarm pull stations, thermostats, IP cameras, and access-control hardware offline. For schools, public buildings, gymnasiums, parking decks, and any deployment scenario where the protected device lives in a high-touch or weather-exposed environment, STI is the integrator-default protection layer that adds material lifecycle to the underlying hardware investment.
