The U.S. government has invested $500,000 so that La Reforma prison workers can see what is happening in the facility.
The new monitoring center contains video screens fed by 86 video cameras.
Cecilia Sánchez, the minister of Justicia y Paz and S. Fitzgerald Haney, the U.S. ambassador, were at the Alajuela prison Thursday for a ceremony involving the monitoring center.
Both officials said that the system would support the human rights of the inmates.
A failed jail break at the prison May 11, 2011, resulted in the death of two inmates and a prison guard. Just days later inmate ringleader Jovel Guillermo Araya Ramírez was found dead in his cell. Medical reports showed he had been beaten multiple times and also immediately before his death.
