Security Protection Systems and Sanders Private Investigations (SPS-SPI) was founded by Bill Sanders in early 1990's. Responsibilities of SPS included installing and monitoring commercial and residential alarm systems, card access systems and camera installations. As part of SPI Bill conducted private investigations for companies and individuals including family cases, subpoena services and background checks.
In August 2010 MCIO purchased the name, customer base, equipment and telephone number of SPS. SPI became a separate entity of SPS at that time. MCIO has taken over the SPS billing, service, installations and customer support for its current and new customers.
