The break-in was reported about 6:30 p.m., prompting a response from the Los Angeles Police Department's Hollywood division.
The caller reported observing four suspects who were recorded by a surveillance camera entering the home through a window at the rear of the hillside residence, an LAPD spokesperson said.
Whether any property was stolen was unclear.
No one was in custody in connection with the burglary, and descriptions of the suspects were not immediately available.
