The teens, both boys ages 15 and 16, were not identified because of their ages. They have been charged in six daytime burglaries in which cash, jewelry, electronics and credit cards were taken.
During a Wednesday news conference, Upper Darby police superintendent Michael Chitwood said one video showed the boys unwrapping Christmas gifts, saying 'Christmas came early this year for us.'
In another incident, Chitwood said the boys couldn't find money in the house. "You could hear them saying, 'Jeez, these people must be poor,'" he said.
The teens gained access to the homes by breaking in rear windows or back doors. They were arrested after they set off an alarm during a break-in and a neighor spotted them.
The teens were a juvenile detention center awaiting court dates.
Both teens have previous police records.
