The Staten Island district attorney's office says 52-year-old Mamura Nasirova pleaded guilty to two misdemeanor counts on Monday. The district attorney says Nasirova will be sentenced to 10 months in jail on June 14.
Nasirova's employers installed the camera after they grew suspicious that the nanny was mistreating the 5-month-old and her 17-month-old brother.
Nasirova was arrested on Feb. 3.
Prosecutors said additional nanny-cam footage that emerged during their investigation showed Nasirova beating both children.
The district attorney's office said Nasirova is not a U.S. citizen and faces possible deportation to her native Uzbekistan.
