The much-delayed state-of-the-art building will house a command and control centre that will receive live feeds from CCTV cameras across the city.
The construction work of the new building began in 2011 and was completed last week.
The Mumbai Police has also established its presence online with Twitter handles for the city's police force and the Commissioner of Police at @MumbaiPolice and @CPMumbaiPolice.
Maharashtra Chief Minister Devendra Fadnavis inaugurated the building.

The Crime Intelligence Unit, Cyber Crime Cell, Missing Persons Bureau, Special Task Force, Property Cell, Economic Offences Wing among others will function from under one roof.
It will also have a citizen's facilitation centre at the ground floor that will serve citizens under a single window system.
Speaking to reporters after the inauguration, Mumbai Police Commissioner Ahmad Javed said, "We had planned it earlier but finally today the Police Housing Corporation handed it over to us. Also, due to increased employment in the police department the problem of space constraint has been solved due to this. This facility will increase our efficiency."
