Jack Osbourne My New Mansion's Like the 'Big Brother' House

All Jack Osbourne needs is Julie Chen and he could shoot "Big Brother" right in his new mansion -- 'cause the place is loaded with more than a DOZEN high-res cameras ... TMZ has learned. 

We know ... Jack O just dropped $3.2 mil on a 5-bedroom, 6-bathroom home in Studio City, CA -- just a few miles from the REAL "Big Brother" house on the CBS lot. 

Sources tell us Jack was looking for a family-friendly neighborhood to raise his 2-year-old daughter Pearl -- and fell in love with the Cape Cod-style home in the Valley.

The bonus is all the high-tech surveillance located all-around the house ... which Jack could probably use considering he's had an issue with a violent unwanted intruder in the past -- his ex-GF who once keyed the living crap out of his Maserati. 

Don't worry -- he's got a Tesla now ... and you gotta be a real a-hole to key a Tesla.
