S.C. prisons assessing anti-cellphone tech

Posted

COLUMBIA (AP) - South Carolina prison officials are assessing a system intended to block cellphones smuggled inside by inmates.

Corrections Department Director Bryan Stirling said officials will be at Lee Correctional Institution in Bishopville on Wednesday to review how a system known as managed access is working.

Managed access interferes with cell signals in a designated area. It doesn't jam all signals, a technology Stirling has said would make his prisons safer.

The state prison system bans inmates from possessing cellphones, saying they are a top security threat because they can help inmates commit crimes. That includes coordinating drug distribution or plotting violent uprisings like a deadly riot earlier this year at Lee.

Officials also use netting, cameras and even drones to try to snuff out cellphones and other contraband at the prisons.
